Officials have released details regarding the death of Brianna Aguilera, the Texas A&M student discovered deceased outside a high-rise in Austin on November 29.

At a press conference on Dec. 4, Austin Police Department officials shared that all of the evidence in their investigation into the 19-year-old’s death is “indicative of suicide.”

Detective Robert Marshall stated, “From the initiation of this call to the present, after reviewing witness accounts, video, and digital evidence, there was never any indication of criminal activity involved.”

Marshall continued, “Our investigation unfortunately shows that Brianna had expressed suicidal thoughts to friends as early as October. These sentiments persisted up until her death, with self-harming behavior observed earlier that evening, along with a text to a friend suggesting suicidal ideation.”

The detective further revealed that a “deleted digital suicide note” was found on Aguilera’s phone, addressed to specific individuals in her life. This note was dated November 24, five days prior to her passing.

Police detailed their timeline, noting their response to a death outside an Austin apartment at 12:46 a.m., where evidence showed trauma “consistent with a fall from a significant height.”

In the day leading up to her death, Det. Marshall said Brianna had gone to a tailgate party in the afternoon “and became intoxicated to a point that she was asked to leave.” She then dropped her phone in a nearly wooded area; the device and other belongings were later recovered by police.

Later that night, Aguilera had visited an apartment building for a gathering at a 17th floor unit, police said, citing surveillance footage. Police said that while a large group of friends left the apartment at 12:30 a.m., Brianna and three other women stayed behind.

With her phone lost, Brianna had borrowed her friend’s phone “to call an out-of-town boyfriend,” Det. Marshall added. “Witnesses heard Brianna arguing on the phone with her boyfriend, which was also later confirmed by the boyfriend.”

According to police, the call lasted for one minute and ended at 12:44 a.m.—two minutes before the 911 call about the dead body was made.

Aguilera’s mother, Stephanie Rodriguez, had questioned police’s investigation, telling People how she reacted when detectives told her they believed her daughter died by suicide.

She told the outlet in an interview published Dec. 2, “It made me very upset because I was like, my daughter wasn’t suicidal. I would know. She’s not suicidal. Why would she be? She was living her best life. She loved life. I mean, she loved going to school. She wanted to become a lawyer.”

Rodriguez added that she instead believed Aguilera had been pushed over the balcony of the apartment building. Police, meanwhile, have said that they found no evidence of a physical altercation or “anything of a criminal nature.”

At the press conference, Austin Police Chief Lisa Davis addressed speculation surrounding Aguilera’s death and why the department opted to speak publicly about the incident.

“It is not common for a police department to speak publicly about a death by suicide, but inaccurate information has circulated and been reported, and that has led to additional harm of innocent people, bullying included, and their families,” she said. “There have also been statements suggesting the police have failed to do our jobs. Those statements are not accurate.”

Chief Davis added, “I understand how grief and the need for answers can raise intense emotions and many questions, but sometimes the truth doesn’t provide the answers we are hoping for, and that is this case.”

Following the press conference, Stephanie Rodriguez shared a video of the conference on Facebook and wrote, “Please don’t believe this lazy investigator and investigation! Tony Buzbee will get us the justice we need,” naming her attorney.

Also following the police press conference, Tony Buzbee announced his law firm would be holding a press conference of their own on Dec. 5 in Houston to “release pertinent details and open questions regarding the investigation” into Aguilera’s death.

Aguilera’s parents will also attend the event and may make statements, Buzbee said.

The attorney shared in a statement of his own, “Brianna Aguilera had her whole life in front of her. The circumstances surrounding her death are very suspicious. The Austin Police Department’s handling of this matter creates more questions than it provides answers. As far as we are concerned, this is an open investigation and will continue to be open until these parents are satisfied they know what happened to their daughter.”
