A former federal prosecutor has urged the Austin, Texas police to delve deeper into the mysterious death of a Texas A&M University student, whose life tragically ended after a heated football rivalry game.

The lifeless body of 19-year-old Brianna Aguilera was discovered in the early hours of Saturday at 12:47 a.m. at the 21 Rio Apartments in Austin, shortly after the Texas A&M University faced off against the University of Texas. While Austin police have stated that her death is not currently being treated as a homicide and have ruled out foul play, Brianna’s mother, Stephanie Rodriguez, is adamant that her daughter was a victim of murder.

According to Rodriguez, detectives have suggested that Aguilera may have fallen from a 17th-floor balcony, labeling her demise as either accidental or a possible suicide. However, Rodriguez is firm in her disbelief of this theory.

“This was not an accident,” Rodriguez passionately expressed on Facebook. “Someone killed my Brie and gave all the group of friends a lot of time to come up with the same story. My daughter would not jump 17 stories from a building, and to be labeling this as a suicide is insane.”

Rodriguez told KSAT that there was a fight between Aguilera and another girl before her daughter’s death.

“There was a fight that happened between my daughter and another girl, and they were all staying in the same apartment that I have actual text messages of, and the detective just disregarded them,” Rodriguez said.

Rodriguez, who said her daughter was drinking that night, said she became suspicious after she saw her daughter’s phone was on “Do Not Disturb,” according to KGNS.

“No one reached out to me, I was the one who had to place several calls to Austin PD because I couldn’t locate her,” Rodriguez said. “What was weird to me and skeptical was her phone was on Do Not Disturb. We always had this rule that if she was going to go out, she had to have her phone on ‘location on’ and answer her text to at least let me know she was OK. That stopped happening around 6 p.m.”

Rodriguez told “Fox & Friends” on Wednesday: “They found my daughter’s phone eventually in her friend’s purse that was thrown in the woods.”

Former federal prosecutor Neama Rahmani told Fox News Digital that Austin police should be giving Aguilera’s death a “closer look,” saying that some elements don’t add up.

“Police should be giving this case a closer look,” Rahmani said. “Either Brianna fell accidentally, she committed suicide, or this was a homicide. Any of them are possibilities.”

“And the fact that there are reports that her phone was on Do Not Disturb, was in a friend’s purse, and that purse was inside the woods, that’s not typical or consistent with just an accident,” he added.

Rodriguez told People she thinks someone threw her over the balcony.

“I’m thinking either someone shoved her over the balcony, or when my daughter does drink, she has the tendency [to fall asleep], and she’s so thin and frail, she cannot handle alcohol,” Rodriguez said. “And I think that maybe either it might’ve been that, and they probably got scared and threw her over the balcony, or they shoved her off.”

The Austin Police Department in a statement on Tuesday said “there is no evidence to suggest or support any suspicious or criminal circumstances surrounding Ms. Aguilera’s passing.”

“Every loss in our community is taken seriously, and every life is deserving of care, dignity, and a complete investigative process. Austin Police extends our heartfelt condolences to Brianna Aguilera’s family, friends, and all who are grieving her loss,” the Austin Police Department wrote.

While a death investigation remains open, a staffer at the Travis County Medical Examiners office, where her body was sent, said that an autopsy takes 90 days or longer.
