(DALLAS) — Police are looking for a missing Texas college student, calling it a “matter of concern.”
Brianna Arango, 21, a student at Southern Methodist University, was last seen midday Thursday on the Dallas campus, according to police.
She was last seen around 12:30 p.m. near Harold Simmons Hall, according to the Southern Methodist University Police Department.
A family member contacted SMU Police at approximately 3:30 p.m. Thursday to report that Arango did not meet with them as planned earlier that afternoon, campus police said. She had a class at 1 p.m. that she also did not attend, police said.
“Based on the information available, SMU Police are actively working to locate Brianna and are treating this as a matter of concern,” the department said in an advisory.
“SMU Police are asking for the campus community’s assistance in locating her,” the advisory added.
Arango was last seen wearing a white shirt, blue sweatpants and carrying a beige tote bag, police said.
Anyone with information on her whereabouts is asked to contact SMU Police at 214-768-3388.

(NEW YORK) — The woman reportedly known as the “Ketamine Queen” is set to be sentenced on Wednesday for providing the ketamine that killed Matthew Perry.
Jasveen Sangha admitted in a plea agreement to working with another dealer to provide the “Friends” actor with dozens of vials of ketamine, including the dose that led to his fatal overdose in October 2023 at the age of 54.
Sangha pleaded guilty last year to one count of maintaining a drug-involved premises, three counts of distribution of ketamine, and one count of distribution of ketamine resulting in death or serious bodily injury.
Sangha faces a maximum sentence of 65 years in prison. She is scheduled to be sentenced Wednesday morning local time in Los Angeles federal court.
Prosecutors said in court filings ahead of Sangha’s sentencing that she should serve 15 years in prison for her “cold callousness and disregard for life,” and that she’s shown little remorse, pointing to recorded jail communications in which, they say, Sangha talked about “obtaining ‘trademarks’ and securing book rights on the events of the case.”
In a sentencing memorandum filed last month, prosecutors said Sangha ran a “high-volume drug trafficking business out of her North Hollywood residence,” where she stored, packaged and distributed drugs, including ketamine and methamphetamine, since at least 2019. Prosecutors said Sangha continued to sell “dangerous drugs” even after learning she had sold ketamine that contributed to the overdose deaths of two men: Perry and, years earlier, Los Angeles resident Cody McLaury. McLaury died hours after Sangha sold him four vials of ketamine in 2019, prosecutors said.
“She didn’t care and kept selling,” prosecutors wrote. “Defendant’s actions show a cold callousness and disregard for life. She chose profits over people, and her actions have caused immense pain to the victims’ families and loved ones.”
Sangha “had the opportunity to stop after realizing the impact of her dealing – but simply chose not to,” which warrants a “significant” sentence, prosecutors also said.
The defense, meanwhile, said Sangha, who has been behind bars since her arrest in August 2024, should receive a sentence of time served due to her “demonstrated rehabilitation.”
“She has maintained sustained and exemplary sobriety, and actively engaged in recovery-oriented and rehabilitative programming while in custody, and has tremendously strong family and community support to facilitate successful reentry and reduce the risk of recidivism,” her attorneys, Mark Geragos and Alexandra Kazarian, wrote in a sentencing memorandum filed last month.
In response to the defense sentencing memorandum, prosecutors continued to argue that Sangha has shown a lack of remorse and claimed she has attempted to minimize the harm she’s caused.
“For example, defendant harmed two overdose victims, but her sentencing briefing does not even mention Cody McLaury and only references Matthew Perry in passing, in the context of defendant attempting to downplay her role in his death and to heap the blame on others,” prosecutors wrote in their response, filed last week.
They also argued that Sangha “expressed a similar lack of remorse in recorded jail communications” – including one on Dec. 25, 2024, during which prosecutors said an individual stated, “We’re gonna sell those book rights,” and Sangha allegedly responded, “Oh I know, the plan is in, the f—— trademark is going down,” according to the filing.
“Even if said in jest, this conversation suggests defendant does not appreciate the severity of her offenses, and instead sees her crimes as a potential future revenue stream,” prosecutors wrote. “It also shows that time in custody has, thus far, failed in getting defendant to adequately reflect upon the grave harms she has caused.”
Geragos has previously said that Sangha “feels horrible.”
“She’s felt horrible from day one,” Geragos told reporters outside the courthouse last year following Sangha’s guilty plea. “This has been a horrendous experience.”
In a victim impact statement filed ahead of the sentencing, Perry’s stepmother, Debbie Perry, said the pain caused by the defendant is “irreversible.”
“Please give this heartless woman the maximum prison sentence so she won’t be able to hurt other families like ours,” she wrote.
In addition to Sangha, four other people were charged and pleaded guilty in connection with Perry’s death: the other dealer, Erik Fleming; Kenneth Iwamasa, Perry’s live-in personal assistant; and two doctors, Mark Chavez and Salvador Plasencia.
Prosecutors said Sangha worked with Fleming to distribute ketamine to Perry, and that in October 2023, they sold the actor 51 vials of ketamine that were provided to Iwamasa.
“Leading up to Perry’s death, Iwamasa repeatedly injected Perry with the ketamine that Sangha supplied to Fleming,” the DOJ said in a press release last year. “Specifically, on October 28, 2023, Iwamasa injected Perry with at least three shots of Sangha’s ketamine, which caused Perry’s death.”
Iwamasa pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine causing death and is scheduled to be sentenced on April 22.
Fleming pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death and is set to be sentenced on April 29.
Chavez and Plasencia have also been convicted for their roles in what prosecutors called a conspiracy to illegally distribute ketamine to Perry.
Chavez, who once ran a ketamine clinic, pleaded guilty in October 2024 to one count of conspiracy to distribute ketamine and was sentenced to eight months home confinement in December 2025.
Plasencia, who briefly treated Perry prior to the actor’s death, pleaded guilty in July 2025 to four counts of distribution of ketamine and was sentenced to 30 months in prison in December 2025.

(UVALDE, Texas) — An attorney for former Uvalde, Texas, school police officer Adrian Gonzales brought a neon orange foam handgun to court on Monday as he tried to defend the police response to the Robb Elementary School mass shooting.
After stepping behind an eight-foot foam board, defense attorney Nico LaHood began his cross examination by asking the witness, a ranger with the Texas Department of Public Safety, “I’m going to point this — do you mind if I point this at you?”
LaHood proceeded to peek his fake weapon out of the foam board while asking the witness, Scott Swick, about the appropriate police response to a mass shooting.
“As a law enforcement officer, you should never rush into a situation without assessing it?” LaHood asked.
“To a point,” Swick said.
Prosecutors allege Gonzales, who is charged with child endangerment, did not follow his training and endangered the 19 students who died and an additional 10 surviving students. Gonzales has pleaded not guilty and his lawyers argue he is being unfairly blamed for a broader law-enforcement failure that day. It took 77 minutes before law enforcement mounted a counterassault to end the May 2022 rampage.
Another witness on Monday was Texas Ranger Terry Snyder, who testified about the shell casings recovered from the hallway of Robb Elementary.
During cross examination, defense attorney Gary Hillier tried to use the testimony to highlight the risk potentially faced by Gonzales.
“Because we’ve seen evidence here that rounds have been fired in this hallway, so anyone who enters through that doorway is entering a potentially life or death situation for them personally?” Hillier asked.
“Correct,” Snyder said.
Prosecutors attempted to recover from the cross examinations by highlighting the urgency of the police response to a mass shooting.
“So, when an officer hears shooting but can’t see shooting, what does the officer do?” prosecutor Bill Turner said.
“Runs to the shooting, where we tactically approach to where the shooting has occurred,” Snyder said.
Monday’s testimony was much more technical than last week’s, when the prosecution’s witnesses included educators who survived the massacre. Teacher Lynn Deming testified that she used her body to protect her fourth-grade students from gunfire and tried to keep them calm.
“I just kept saying, you know, like, ‘Babies, I love you. Just pray, I love you, OK,'” she testified as she held back tears. “I just wanted the last thing they heard was that somebody loved them. So, I think I said it a million times.”
Friday also brought the first testimony from a parent of a victim. Jennifer Garcia, whose 9-year-old daughter Eliahna Amyah Garcia was killed, told jurors, “We couldn’t find her. Kids were just running everywhere.”
According to former acting Dallas District Attorney Messina Madson, prosecutors appeared to be using their first witnesses to lay bare the tragedy that took place before turning their focus to Gonzales specifically.
“This is an unusual way to apply this law, and so from an overall point of view of what the district attorney’s office is trying to do is say this is a tragedy,” Madson, now a criminal defense attorney at MC Criminal Law, told ABC News. “This is a terrible, horrible thing that happened, and it is so horrible that not only do we have to mourn it, but somebody is criminally responsible, besides the person who pulled the trigger.”
According to Madson, prosecutors will need to clearly identify what opportunities Gonzales had to intervene and how close he was to the shooter to prove he “intentionally, knowingly, recklessly and with criminal negligence” placed students in harm’s way.
“It’s saying that somebody in those circumstances would have understood the risk and would have intervened and … you behaved in a way that was not how a reasonable person would in that situation,” Madson said.

(CORPUS CHRISTI, Texas) — A Robb Elementary School teaching aide testified that she repeatedly urged Uvalde, Texas, school police officer Adrian Gonzales to intervene in the shooting, but said he did “nothing” in those crucial moments.
Melodye Flores testified on Wednesday that she saw gunman Salvador Ramos before he entered the school and tried to tell Gonzales his location.
“I told him that he needed to get stopped before he went into the fourth-grade building,” she testified.
“And what did he say?” prosecutor Bill Turner asked.
“He, just, nothing,” Flores said.
“Did you say it more than once?” Turner asked.
“I did,” Flores said, telling jurors she urged Gonzales to intervene two or three times.
Prosecutors allege Gonzales, who is charged with child endangerment, did not follow his training and endangered the 19 students who died and an additional 10 surviving students.
Gonzales, no longer an officer, has pleaded not guilty and his lawyers argue he is being unfairly blamed for a broader law-enforcement failure that day. It took 77 minutes before law enforcement mounted a counterassault to end the May 24, 2022, rampage.
Flores testified that she was eating lunch in her classroom when she learned about the shooter over a school radio. She said she ran outside because she knew that some students were on the playground and potentially in danger.
After warning some students, Flores said she spotted the gunman near the south door of the school.
“He was wearing all black and a hoodie … that’s when he started shooting,” she said.
Flores said she started running away and tripped, and incorrectly thought she was shot.
She testified that she saw Gonzales drive up to her right after she tripped, and she tried to inform the officer about the shooter’s location.
“I said that he was heading into the fourth-grade building, and we needed to stop him. We needed to go in and stop him before he went in,” she said.
“I just kept pointing. ‘He’s going in there, he’s going to the fourth-grade building,'” she told jurors.
“Did you hear anything from this gunman while you were talking to the police officer?” Turner asked.
“Just kept hearing shots,” she said.
Flores said that Gonzales did not respond to her warnings.
“I kept telling him that he needed to be stopped,” she said.
“When you told the officer to go in, did he go in?” Turner asked.
“No,” she said.
“What did he do?” Turner asked.
“He just stayed there,” she said.
Flores said she left Gonzales and tried to help a teacher who had sheltered in her classroom.
On Tuesday, during the testimony of Texas Ranger Ricardo Guajardo, prosecutors played a lengthy interview Gonzales gave to state investigators after the shooting.
In the interview, Gonzales recalled arriving at the school as one of the first officers and learning about the shooting from a coach.
“I was going over there towards her,” he said. “I see her fall in the dust cloud. So I get to her, and I realized she’s one of the coaches.”
According to Gonzales, he learned the approximate location and a basic description of the shooter from the coach, though the shooting began before he could act.
Gonzales told investigators that he could not see the shooter, but he tried to notify others over his radio.
“I notify everybody on the radio, the best I could. And then, you know, as soon as I start walking over there, I see the rounds come out of the window,” he said.
Gonzales also described trying to enter the school with four other officers, though they retreated after two were hit by gunfire.
“Everybody flew back, you know, so I think he got hit,” he said. “We kind of moved back.”
Two months before the shooting, Gonzales taught a course about responding to active shooters, according to testimony from Teresa Zamarripa, the officer manager at Southwest Texas College Law Enforcement Agency.
