People trapped under rubble after explosion at Pennsylvania steel plant, rescue operation underway: Officials

(NEW YORK) — A second suspect in the weekend shooting of an off-duty United States Border Patrol agent in a New York City park has been taken into custody, authorities said on Monday.

Homeland Security Secretary Kristi Noem said an accomplice of the suspect in the shooting and wounding of the off-duty Customs and Border Protection (CBP) officer was detained over night.

Noem did not initially identify the second person, but said he is also an undocumented migrant as she gave an update on the shooting at a press conference in New York.

The officer, who was shot in the face and arm just before midnight on Saturday, remained hospitalized and is expected to survive after exchanging gunfire with an undocumented migrant with a lengthy criminal record and outstanding arrest warrants. The suspected gunman, 21-year-old Miguel Francisco Mora Nunez, an undocumented migrant from the Dominican Republic, was also shot in the incident and detained after he went to an area hospital for medical treatment.

Both suspects are believed to have entered the U.S. during the Biden administration, according to authorities. Noem, border czar Tom Homan and CBP Commissioner Rodney Scott blamed former President Joe Biden and sanctuary city policies for permitting the men to remain in the country.

Mora Nunez entered the U.S. illegally in 2023 and was released, Noem said. He has an active warrant for armed robbery in Massachusetts, according to officials.

U.S. Attorney for the Southern District of New York Jay Clayton said federal charges are expected in the case.

The shooting unfolded at 11:51 p.m. Saturday in Fort Washington Park in the Washington Heights neighborhood of upper Manhattan, according to the New York Police Department.

The 42-year-old Border Patrol agent was taken to Harlem Hospital, where he is being treated and is expected to make a full recovery, authorities said.

The shooting occurred near the Little Red Lighthouse in Fort Washington Park, which is directly beneath the George Washington Bridge, police said. The attack was captured on security video, which helped police quickly catch the suspect, authorities said.

A witness told police that she and the off-duty agent were sitting together on the rocks near the edge of the Hudson River when the suspected gunman and his accomplice approached them on a scooter, according to a DHS statement released on Sunday.

The security video, posted on social media by the DHS, showed two men on a scooter stop near where the victim and the witness were sitting. In the footage, the passenger is seen getting off the scooter and approaching the victim while the driver stays with the vehicle.

New York City Police Commissioner Jessica Tisch said at a news conference Sunday afternoon that the video showed Mora Nunez allegedly drawing a firearm and the Border Patrol agent also pulling out a handgun to defend himself.

“The officer realized that he was being robbed and drew his service weapon in defense,” Tisch said.

Tisch alleged that Mora Nunez opened fire first and that there was an exchange of gunfire before the suspect appeared to limp back to his alleged accomplice and the two drove away on the scooter.

Tisch said Mora Nunez walked into a hospital in the Bronx at 12:18 a.m. with gunshot wounds to the groin and the leg that she said was “consistent with the injuries sustained” by the perpetrator in the security video.

The commissioner said it does not appear that the Border Patrol agent was targeted because of his job.

Mora Nunez underwent surgery and is in custody at Lincoln Hospital in the Bronx, Tisch said.

The initial police investigation has determined that the suspect, who DHS said is from the Dominican Republic, entered the country illegally in Arizona from Mexico in 2023, according to Tisch.

Tisch said Mora Nunez has two prior arrests for domestic violence in New York and has an active warrant for missing a court date on one of the cases.

Mora Nunez is also wanted by the NYPD for a robbery in December 2024 and a felony assault stabbing in January 2025. Both of those incidents occurred in the Bronx.

“In less than one year, he has inflicted violence in our city and once he’s charged for last night’s crimes, we will be able to add attempted murder to his rap sheet,” New York City Mayor Eric Adams said at Sunday’s news conference.

The Massachusetts warrant for Mora Nunez alleges he stole guns from a pawn shop in February 2025, Tisch said.

Adams said he visited the wounded Border Patrol agent in the hospital on Sunday.

The New York shooting comes roughly two weeks after a gunman opened fire at the entrance to the Border Patrol sector annex in McAllen, Texas.

The suspect in the July 7 shooting, identified as 27-year-old Ryan Louis Mosqueda, fired “many rounds” at the federal building that houses the U.S. Border Patrol office at the McAllen International Airport, according to McAllen Police Chief Victor Rodriguez.

The suspect was confronted and killed by Border Patrol agents and local police, according to McAllen police and the DHS.

Two police officers and a Border Patrol employee were injured in the attack, according to the DHS.

The motive for the McAllen shooting remains under investigation.

(UVALDE, Texas) — Two months before a gunman killed 19 children and two adults at Robb Elementary School in Uvalde, Texas, the school district’s then-police chief was required to attend a training about how to respond to an active shooter, which instructed in no uncertain terms that an “officer’s first priority is to move in and confront the attacker.”

When Pete Arredondo, the police chief of the Uvalde Consolidated Independent School District at the time of the May 2022 shooting, was confronted with precisely the situation his training should have prepared him for, he did the opposite of what the training instructed would have saved lives, according to a newly released trove of documents from the Uvalde school district.

“Time is the number one enemy during active shooter response,” a lesson plan for the training said. “The best hope that innocent victims have is that officers immediately move into action to isolate, distract, or neutralize the threat, even if that means one officer acting alone.”

More than three years after the shooting and the training designed to prevent it, Arredondo continues to fight a criminal case that alleges that he was responsible for putting students in danger by waiting 77 minutes to confront the gunman, who had holed up in adjoining fourth-grade classrooms.

Arredondo has pleaded not guilty to 10 counts of child endangerment and abandonment on behalf of the injured and surviving children. His trial date is set for October 2025.

“From the benefit of hindsight where I’m sitting now, of course, it wasn’t the right decision. It was the wrong decision, period,” then-Texas Department of Public Safety Director Steven McCraw told reporters days after the shooting.

The records of the active shooter training were included in a trove of documents released by the Uvalde School District on Monday, following a years-long effort to withhold the documents about the school district’s response, security, and police training. After years of requests from the families of victims, the public, and media organizations, including ABC News, the records were released on the eve of the new school year, as prosecutors prepare to bring two former school district police leaders, including Arredondo, to trial.

Paul Looney, an attorney for Arredondo, said in a statement to ABC News, “There is very little that will shed any constructive light on what to do next time or who did or didn’t do anything this last time. Much is being made of trying to keep information private and secret so that they can try to prosecute two officers. Those prosecutions are flawed. They are not going to be successful, but the hiding of information is hiding a gold mine that we need to be learning from so that we can handle it more constructively next time. I’ve seen all this stuff in discovery for quite a while now. The hiding of this is pointless and serves nobody any constructive purpose.”

“I’m not sure if my battle for transparency will ever truly be over,” said Gloria Cazares, the mother of 9-year-old Jackie Cazares, who was killed in the massacre. “I need to know everything that led up to my daughter’s death and what happened after. Every detail matters. If we can’t get justice, then the very least we deserve is every piece of evidence, every record, every truth that has been kept from us.”

Among the hundreds of pages released, the records suggest that the flawed response was not because of a lack of training, but in spite of it. The Texas state legislature passed a law in 2019 that required school resource officers and police to participate in an approved active shooting training within 180 days of their employment. One such training in Uvalde took place on March 21, 2022, two months before the deadly shooting.

“First responders to the active shooter scene will usually be required to place themselves in harm’s way and display uncommon acts of courage to save the innocent,” the training said. “A first responder unwilling to place the lives of the innocent above their own safety should consider another career field.”

The training also includes material about the flaws in the emergency response to the February 2018 deadly school shooting in Parkland, Florida, where officers faced criticism for staging outside the building while the shooting took place. According to the materials, the training in Texas was mandated to prevent a similar tragedy from taking place, where a delayed law enforcement response could potentially contribute to additional casualties.

The newly released documents also shed light on the academic and disciplinary history of the deceased gunman, Salvador Ramos. The 18-year-old student was disciplined for inappropriate behavior at least 18 times between 2015 and 2018, including bullying other classmates, using inappropriate and sexual language, and fighting his peers, the documents say.

Ramos’ incidents show a clear and documented pattern of low-grade but increasing and recurrent behavioral issues in school, according to the documents. His acting out was written up multiple times, but there was no clear follow-up documented to address his needs and help him. His parents were often absent from the process, the documents show.

His mother Adriana Reyes told law enforcement prior to the shooting that she was “scared” of her son. Speaking to ABC News after the shooting, Reyes said her son could be “aggressive” but he was not a “monster.”

“We all have a rage, that some people have it more than others,” Reyes said

In November of 2015, a disciplinary write-up noted Ramos wrote “I’m gay” on the back of another student’s artwork planning sheet, according to the documents. Though he denied it, the student whose paper it was identified Ramos as the culprit. When the teacher called Ramos’ mom, “it said this person is unavailable. I also tried calling grandfather’s phone, and it said voicemail is full,” the documents show.

In March 2018, Ramos was written up for truancy and got suspended, according to the documents. Also that March, he was written up for “‘using sexual language’ after repeatedly [being] told to stop.” When told to do his work by a teacher, the documents say he flashed the “L” loser sign and was placed under in-school suspension.

Ramos was written up for drawing an “inappropriate picture” on an assignment in May 2018 and received in-school suspension, according to the records. The same month, a handwritten note in pink pen said he was sent to the office because “he refused to do his work. I told him to put his head down for the whole class or go to the office. He decided to go to the office.”

Also in May 2018, Ramos “went up to a student and hit him in the arm. Another student reacted by kicking him,” according to the documents. Under parent contact, the documents show the disciplinary record said, “no answer.”

(NEW YORK) — After a gunman opened fire in a New York City office building and killed four people, experts expressed some concerns regarding security in workplace environments.

Four people were killed and one was injured on Monday after police say 27-year-old Shane Devon Tamura entered a Midtown Manhattan office building — which is home to the NFL headquarters — wearing body armor and opened fire with a high-powered rifle, according to authorities.

Donald Mihalek, a senior ABC News law enforcement contributor and retired United States Secret Service agent, said these types of workplace shootings are on the rise due to people — employees and those not affiliated with the company — feeling more comfortable with vilifying corporations and taking out their grievances through violence.

From 1994 to 2021, 16,497 U.S. workers were “intentionally killed while at work,” according to 2024 study. Other recent shootings that occurred at workplaces include the 2021 incident at an office complex in Southern California, killing four people, and a 2023 incident at a bank in Kentucky, killing five and injuring eight.

“Corporations are now feeling what governments have felt for many years, being targeted, being vilified,” Mihalek told ABC News.

So, what was learned from this incident and how can office buildings help mitigate these shootings from escalating?

Security outside an office building and artificial intelligence monitoring potential threats

On Monday, the suspect emerged from a double-parked BMW with an M4-style weapon Palmetto State Armory PA-15 rifle, entered the lobby alone, immediately opened fire on a New York Police Department officer and sprayed the lobby with bullets.

Richard Frankel, an ABC News contributor and retired FBI special agent, said Tamura’s ability to leave his vehicle double-parked and walk with a visible weapon “without anyone even thinking about it or causing concern” is “a little bit of an issue.”

“It’s crazy that he was able to walk on a Manhattan street into a building and not be seen carrying a long gun,” Frankel told ABC News. “How was he able to just walk with no one seeing him carrying an assault weapon and actually having it dangle out from his jacket?”

To prevent something similar happening in the future, Frankel said a corporation increasing its security presence outside the building — by establishing a private government partnership or hiring individuals — could help prevent the threat from actually entering the presence.

Frankel also said there is artificial intelligence and video technology used by federal buildings that could “observe what somebody is doing and consider whether that’s a threat or not.” If an armed individual is approaching the building, “an alarm would go off” with this technology, Frankel said.

Understanding the difference between handgun and rifle violence

With this shooting, the gunman opened fire using a rifle, which is a “more powerful weapon” that can travel a greater distance and has a greater capacity to penetrate compared to a handgun, Mihalek said.

Thus, corporations should think to make a “significant investment” in armor and bulletproof glass around the entranceways of the building, he said. While it is “very difficult” for someone to protect themselves from a rifle, a “man trap system” — where somebody has to be let through different phases of the building in order to get to the heart of the structure — could also help slow down the attack.

Conducting threat assessments

Mihalek also recommends that corporations conduct threat assessments, where a business identifies individuals — both employees and those not affiliated with the company — who may be potential threats of violence due to a recent termination, relationship turmoil or social media posts showing grievances toward the company or individuals at the company.

While it is unclear whether the suspect in Monday’s shooting was posting threats on social media, officials had found a note in his pocket accusing the National Football League of concealing the dangers to players’ brains to maximize profits, sources said. So “chances are he had some type of social media presence or online presence somewhere where he might have said a few things about the NFL,” which could have alerted of a potential threat beforehand.

This behavioral assessment is a holistic process that detects, identifies and processes potential threats, Mihalek said.

“This individual could have perhaps said something concerning online or elsewhere but if no one reports it or is looking, it can’t be detected,” Mihalek said.

Implementing active shooter drills, training for employees

Along with buildings implementing additional security and keeping a lookout for potential threats, both Mihalek and Frankel said corporations should implement routine active shooter drills and provide both online and in-person training conducted by local law enforcement.

Mihalek said buildings should also partner with local law enforcement and emergency medical services so they can “understand the layout of the building” so that they are prepared for a potential threat to that particular office space.

The Department of Homeland Security also has basic active shooter protocols instructing individuals in an active shooter situation to “run, hide and fight,” which Mihalek said is used in many schools and is “simple, effective and it works.”
