More than a month after a Texas A&M student plunged to her death from a 17-story balcony, her family presented new evidence that could blow open the police's claim she died by suicide.

Brianna Aguilera, a 19-year-old sophomore, plunged from an apartment building in the state capital on November 28 after attending the annual rivalry football game between Texas A&M and the University of Texas at Austin.

Investigators later concluded that Aguilera took her own life, revealing in December that they had found what they described as a suicide note on her phone.

But at a press conference in Houston on Tuesday, the teenager’s family - represented by attorney Tony Buzbee - introduced a neighbor who says she heard disturbing sounds from Aguilera’s apartment in the moments before the fatal fall. 

Dannah Rodriguez, who lives at the collegiate apartment complex 21 Rio where Aguilera was staying while visiting Austin, said she heard yelling and what appeared to be a heated argument involving multiple people. 

'I began hearing a girl arguing with other people,' Rodriguez recalled. 'It sounded like it was multiple people in the apartment pacing back and forth so it was hard to recall what was said in the argument.'

The Austin Police Department believes Aguilera killed herself, revealing in December that investigators found a suicide note on her phone.  

Rodriguez said the confrontation escalated to the point that her mother, who was visiting at the time, considered crossing the hallway to intervene — moments before Aguilera plunged from the balcony.

Austin Police revealed in December that Brianna had a deleted suicide note on her phone from earlier in the week, along with suicidal texts she sent to friends the night she jumped

They heard loud screaming and then eventually the noise died down. 

Rodriquez told reporters she has lived across the hall from 'Natalie' for nearly a year and could hear everything that went on in Natalie's apartment through the 'paper thin' walls. 

Natalie, whose last name was not revealed, is a friend of Aguilera's who hosted her that weekend and often threw parties  after Texas football games. 

'My understanding is that Natalie immediately vacated her apartment after Brianna died, and over the Christmas break, my parents and I saw through the peephole...her parents were grabbing things from the apartment, vacating out.'
