In a heartbreaking turn of events, Brianna Aguilera, seen joyfully wearing a pink fantasy costume alongside her college love, tragically fell from a 17th-floor balcony following an exuberant football tailgate celebration.

According to sources, the ill-fated student was in a relationship with Aldo Sanchez, a fellow 20-year-old student at Texas A&M University, both hailing from Laredo, a border city they called home.

Adding to the tragedy, authorities have disclosed that Aguilera had a phone dispute with her boyfriend merely three minutes before her fatal fall.

Yet, it was just over a month ago that she was radiantly happy in a photo with Sanchez.

In this image, she wore a sparkling crown and clutched a glittery wand, embodying Glinda, the beloved character from L. Frank Baum’s Oz tales.

Sanchez, his arm around her, also has a broad smile as he stands in a flamboyant green and gold jacket as charismatic Prince Fiyero, from the Wicked movies, which are the prequel to the Wizard of Oz.

Just 29 days later Brianna’s body was discovered outside a student apartment building in Austin after she’d traveled to the city for her college’s game against the University of Texas.

Her mother Stephanie Rodriguez has been battling Austin Police’s assertion that her daughter’s death was suicide following a raucous boozy Friday night where the student was involved in a fight.

The image takes on tragic new weight as cops say Aguilera had a heated phone argument with her boyfriend just three minutes before she plunged from the 17th-floor apartment where 15 others were partying

Although police ruled her fall a suicide on Thursday, her mother, Stephanie Rodriguez, fiercely disputes that, calling the idea ‘insane’ and insisting her daughter would never jump from that height

However, Austin Police revealed Thursday that there was a deleted suicide note on Brianna’s phone from earlier in the week.

There were also suicidal texts sent the evening of her death to friends.

Austin Police Chief Lisa Davis said: ‘It is not common for a police department to speak publicly about a death by suicide.

‘But inaccurate information has been circulated and reported. And that has led to additional harm of innocent people, bullying included, and their families.’

During a news conference, police also revealed Aguilera had made previous comments to friends indicating she could be suicidal.

This makes the loving images of Aguilera and Sanchez together all the more heartbreaking following a detective’s revelation at the conference that she had an argument ‘with her boyfriend’ before plunging to her death.

Aguilera was among 15 others at an apartment on the 17th floor and Rodriguez insisted on Facebook earlier this week: ‘This was not accidental. 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.’

Austin Police revealed Thursday 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

Loving images of Aguilera and Sanchez together are plastered on the couple’s social media accounts, with two from February 15 and March 2 embracing as they smile into the camera

The tragedy followed what appears to have been a blissful year of being romanced for Aguilera, with her cataloguing her time with Sanchez in a series of loving snaps on social media.

These begin on February 15 with a shot of the pair in each other’s arms, followed by another hugging picture on March 2.

On April 12, both are clad in New York Yankees gear and appear to be at the game where the Bronx Bombers beat the San Francisco Giants 4-8. Aguilera is holding an alcoholic Twisted Tea Peach and Sanchez is clutching a Miller Lite.

By August 1, the young beau certainly wears his heart on his sleeve. A shot Aguilera posted shows her with a magnificent bouquet of red and pink roses as they sit at a restaurant.

At the end of August, Aguilera is in a Texas A&M shirt with Sanchez, with a football and a heart on the pic as the pair clutch cans of White Claw hard seltzer.

Clad in white college logo adorned cowboy boots, she beams again for the shot with Sanchez on October 4 where Texas A&M beat Mississippi State – before her final pic of them together in the month that she died.

Her mother referred to a ‘boyfriend’ in an interview with Fox & Friends but did not reveal his name or specify their status at the time of her daughter’s death.

On August 1, Sanchez staged a grand romantic ask – sharing a photo of Aguilera beaming over a massive bouquet of red and pink roses beside a dessert plate card dotted with hearts reading, ‘Will you be my girlfriend?’ 

Things still appeared to be in the honeymoon phase from August to October as the couple posed together at Texas A&M football tailgates, where they both went to school 

Rodriguez, 38, raised the alarm after she could not contact her daughter on the Friday evening of the party and saw her phone had been set to ‘do not disturb’.

The mom said: ‘She was not allowed to put her phone on do not disturb or even ever change her location so when she stopped responding to my calls, which was around 6pm when I noticed her phone was on do not disturb… Brianna would never do that.

‘So, I said OK maybe she’s at the tailgate party, her boyfriend didn’t go with her, they’re having issues, that’s ultimately what I thought.’

Rodriguez, 38, raised the alarm when she couldn’t reach her daughter that Friday night and noticed her phone was set to ‘Do Not Disturb’ 

Sanchez, whose father Eduardo and mother Maria have a $528,000 home in Laredo, attended St Augustine High School in the city and was honored in 2024 with a sector Border Patrol youth of the month award.

Aguilera attended the city’s United High School and went on to win a place a Texas A&M’s Bush School of Government and Public Services in College Station from where she was hoping to become a lawyer.

She was excited to go home to Laredo from college for a planned six-week break and was in Austin just for the game which she didn’t attend, her mother said.

But while at the party, Rodriguez told police that her daughter had ‘become intoxicated’ at the student block apartment where she was staying and that she’d fought with another girl.

Her body was discovered outside the building in the West Campus area of Austin at 12.46am Saturday and she was identified from her fingerprints.

Rodriguez told police that her daughter had become intoxicated during the party at the student apartment and had argued with another girl. Hours later, at 12.46am Saturday, her body was discovered outside the West Campus building and identified by fingerprints

According to Detective Robert Marshall, Aguilera had been so drunk that she was asked to leave an Austin Rugby Club tailgate at 10pm that night

Detective Robert Marshall told the news conference Thursday: ‘A further review of Brianna’s phone shows a delated digital suicide note dated Tuesday, November 25 of this year, which was written to specific people in her life.

‘From the moment this call originated up until now, between all the witness statements, all of the video evidence and all of the digital evidence collected, at no time did any evidence point to this being anything of a criminal nature.

‘Rather, our investigation has revealed that unfortunately, Brianna had made suicidal comments previously to friends back in October of this year.

‘This continued through the evening of her death, with some self-harming actions earlier in the evening and a text message to another friend indicating the thought of suicide.’

Detective Marshall said Aguilera had been so drunk on that fateful night that she had been asked to leave a tailgate party at Austin Rugby Club at 10pm.

He added she’d had a fight with her ‘boyfriend’ – who was not in Austin – by phone at 12.43am, minutes before plunging to her death. She’d lost her own cellphone at the tailgate and borrowed a friend’s.

Detective Marshall said: ‘Witnesses heard Brianna arguing on the phone with her boyfriend which was confirmed later by the boyfriend.’

The dramatic twist in the story comes after Rodriguez claimed her daughter’s phone was ‘thrown into woods’ near a creek as part of the mystery over her death.

But Rodriguez has been steadfast that her daughter didn’t commit suicide, claiming the 19-year-old’s phone was ‘thrown into woods’ near a creek as part of the mystery over her death

Her mother also alleged the friends who were at the party had participated in a cover-up as they stayed quiet and the person who live at the apartment had suddenly vacated it after she allegedly jumped

She alleged the friends who were at the party had gone silent as part of a cover-up and that the person who lived at the apartment had suddenly vacated it.

Rodriguez told People: ‘I’m thinking either someone shoved her over the balcony, or when my daughter does drink, she has a tendency (to fall asleep) and she’s so thin and frail, she cannot handle alcohol.

‘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.’

Daily Mail can reveal that balcony is at least 3ft 6in high compared to Aguilera who was 5ft 2in. Underneath all the balconies, there is a wide ledge on the seventh floor containing an outdoor gym and eating area.

Aguilera’s family have organized a mass honoring her life at St Patricks’ Catholic Church, Laredo on December 9 followed by a cremation. There will be a public vigil the previous evening. 

The Sanchez family declined to comment when contacted by the Daily Mail.
