The Austin Police Department Chief, Lisa Davis, and the lead detective in this case, Robert Marshall held a news conference Thursday to address online and reported speculations surrounding Brianna’s death.

Davis said it is not common for a police department to speak publicly about a death by suicide, but inaccurate information has circulated and been reported.

“That has led to additional harm to innocent people, bullying, included and their families. There’s also been statements that police have failed to do their jobs. Those statements are not accurate. 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,” she said.

She said careful investigations take time, detectives must interview witnesses, collect evidence, and piece together facts, releasing partial evidence too early could jeopardize the case.

Detective Marshall gave a timeline leading up to Brianna’s death and after:

Family questions official findings

Despite investigators’ conclusions, Aguilera’s mother, Stephanie Rodriguez, publicly rejected the notion that her daughter took her own life.

In a Facebook post, Rodriguez wrote, “This was not accidental. Someone killed my Brie… My daughter would not jump 17 stories from a building.”

Rodriguez also spoke with KPRC 2 News earlier this week.

Rodriguez’s concerns have fueled ongoing discussion among students and online communities.

Aguilera’s parents also announced Wednesday that they have hired prominent Houston attorney Tony Buzbee to investigate the situation and “determine what happened” to their daughter.
