Brianna Aguilera, a cheerleader from Texas A&M, was recently seen beaming with joy in photos with her boyfriend, Aldo Sanchez, just weeks before a tragic incident. The couple, who seemed deeply in love, were captured in vibrant Halloween costumes, with Aguilera dressed as Glinda and Sanchez as Prince Fiyero from the “Wicked” films. This cheerful image has since become poignant, as it preceded an argument overheard on the phone that ended with Aguilera falling 17 stories from an apartment building.

Aguilera and Sanchez, both 20, exuded happiness and affection in various photos shared throughout the year. The couple appeared smitten, showcasing their close bond and mutual admiration in each image. Their playful Halloween costumes, with Sanchez sporting a striking green-and-gold jacket, highlighted their shared sense of fun and closeness.

Other snapshots from earlier in the year reinforce this image of a couple deeply connected. On February 15 and March 2, they were pictured embracing, radiating joy and warmth. Another memorable moment captured on April 12 shows them dressed in New York Yankees gear, enjoying a game at Yankee Stadium with drinks in hand, further emphasizing their shared experiences and affection.

In photos posted on Feb. 15 and March 2, the couple appeared radiant as they embraced.

In an April 12 photo, the pair are clad in New York Yankee gear, posing at a Bronx Bombers game with their drinks.

On August 1, Aguilera posted a photo holding a lavish bouquet of red and pink roses with a heart-adorned card on a dessert plate that read: “Will you be my girlfriend?”

Their final photo together on Halloween was snapped almost a month before Aguilera arrived at her Austin apartment complex just after 11 p.m. on Nov. 28, following a Texas A&M vs. UT tailgate, and plunged 17 stories to her death, police said.

Austin Police Detective Robert Marshall said at a news conference Thursday that Aguilera had become “intoxicated to a point where she was asked to leave” the tailgate.

The cheerleader told friends she had lost her phone and borrowed someone else’s cell to call her boyfriend from 12:43 to 12:44 a.m. when she arrived back at the complex, Marshall said.

Witnesses heard Aguilera arguing with Sanchez on the phone at 12:44 a.m. Saturday morning, just two minutes before a 911 call was made.

Police were called to the apartment complex less than two hours later, where they found Aguilera’s body.

Police said a deleted suicide note was on her phone, as well as suicidal texts sent on Friday night to friends. The 19-year-old had also previously made comments to friends indicating she may be suicidal.

Aguilera’s mom, Stephanie Rodriguez, has dismissed the cops’ version of events and insisted that her daughter wasn’t suicidal.

“Please don’t believe this lazy investigator and investigation!” she wrote in a Facebook post sharing a video of Thursday’s press conference.

The heartbroken mother previously shared that her daughter’s phone was on Do Not Disturb the night of her death, and that the teen knew to keep her alerts on when she went out.

The phone was later discovered by a creek, where it had been left since 6:30 p.m. Friday.

Police have said they won’t investigate the death as a homicide.

Rodriguez has hired hot-shot Texas attorney Tony Buzbee, who represented over 150 alleged victims of Sean “Diddy” Combsto, to investigate her daughter’s death.

“They feel certain this was not an accident. This was certainly not a suicide. The family deserves straight answers. We hope we can help them get those answers,” he wrote on his social media accounts.

Buzbee said his office will hold a press conference in Houston on Friday to discuss the case in depth.
