Newly released court documents have revealed chilling new details about the final minutes of a Texas mother of five before she was fatally stabbed, including surveillance images that investigators say captured the entire attack from beginning to end.

Authorities allege Caroline Raquel Peña, 32, was standing calmly outside a Del Rio home, smiling as she spoke on her cellphone, only moments before she was confronted by three young women now charged with her murder.

According to a criminal complaint, the fatal confrontation unfolded on June 25 outside the home of 21-year-old Kyandra Renee Faz and was recorded by a home surveillance camera overlooking the property.

The footage has become a central piece of evidence in the investigation as prosecutors prepare their case against Faz, 19-year-old Amaya “Cookie” Diaz and 21-year-old Kitty Mia Diaz.

All three women have been charged with murder in connection with Peña’s death.

Investigators say the surveillance recording begins with Peña arriving at Faz’s residence during the afternoon.

Doorbell camera images included in the investigation reportedly show the mother of five appearing relaxed as she stood near the entrance while talking on her cellphone.

She appeared to have a slight smile on her face during those final moments before violence erupted.

Police say the atmosphere changed only minutes later.

According to the criminal complaint, a black Chrysler 300 pulled up outside the residence carrying the Diaz sisters.

Investigators allege Amaya Diaz exited the vehicle while holding an object that detectives believe was a knife.

The complaint states that she immediately approached Peña.

According to investigators, Amaya then stabbed Peña in the back.

Authorities say surveillance footage captured the alleged attack in its entirety.

The recording reportedly shows blood quickly soaking the back of Peña’s shirt following the stabbing.

Detectives further allege that after the initial attack, Kitty Diaz and Kyandra Faz joined the confrontation.

According to the complaint, both women allegedly assaulted the already seriously wounded victim before all three suspects fled the area.

Police have not disclosed precisely how long the attack lasted.

Nor have investigators released the surveillance footage publicly because it remains evidence in the ongoing criminal case.

However, court documents describe the recording as documenting the complete sequence of events.

Authorities believe it provides investigators with a detailed visual account of the confrontation from beginning to end.

The motive behind the deadly encounter remains unclear.

Investigators have confirmed only that the victim and the three suspects knew one another before the incident.

Police have not explained the nature of those relationships or whether previous disputes existed among them.

During questioning, Kyandra Faz reportedly acknowledged that Peña came to her residence before the attack.

According to the criminal complaint, Faz claimed the victim had arrived “looking to start a fight.”

Authorities have not commented publicly on whether evidence supports that account.

Investigators also have not indicated whether the confrontation was planned in advance or escalated unexpectedly after Peña arrived.

Those questions remain central to the continuing investigation.

After the attack, Peña was rushed toward medical care by family members.

According to investigators, her nephew drove her to a nearby hospital shortly after she suffered the stab wounds.

Because of the severity of her injuries, medical personnel later arranged for her to be airlifted to a hospital in San Antonio.

Despite extensive efforts by doctors, Peña died approximately seven hours after the attack.

Her death transformed the investigation into a homicide case.

Friends and relatives have since remembered Peña as a devoted mother whose greatest priority was raising her five children.

Her death has left family members grieving while preparing to navigate life without her.

The arrests came quickly.

Investigators identified the three suspects through surveillance footage and other evidence collected during the investigation.

Police later located the Diaz sisters.

Authorities allege both women had changed clothes and showered before officers arrived at their residence, circumstances investigators considered significant while gathering evidence.

Just hours after the fatal attack, police escorted the sisters into custody.

Video recorded during the arrests later spread widely online.

The footage appeared to show Amaya Diaz smiling broadly while officers led her toward a patrol vehicle in handcuffs.

The images generated widespread public reaction as the case attracted national attention.

Kyandra Faz was arrested separately after investigators located her.

All three women appeared in court for the first time days later.

During that hearing, each requested court-appointed legal representation.

A judge ordered all three held on bonds of $5 million each.

They remain in custody while the criminal proceedings continue.

Police have emphasized that the investigation remains active despite the arrests.

A department spokesperson said detectives continue examining evidence and have not yet publicly announced what they believe sparked the fatal confrontation.

Investigators are expected to continue reviewing surveillance footage, interviewing witnesses and analyzing forensic evidence before prosecutors present the case at trial.

The surveillance recording itself is expected to become one of the prosecution’s most important exhibits.

According to the criminal complaint, the camera documented every stage of the confrontation.

That evidence may help jurors reconstruct exactly how the attack unfolded and clarify the alleged role each defendant played during the incident.

Legal experts note that surveillance video often becomes particularly influential in violent crime prosecutions because it provides an objective record independent of witness recollections.

Whether additional security cameras from neighboring homes or businesses captured portions of the incident has not been disclosed.

Authorities likewise have not revealed whether investigators recovered the weapon believed to have been used.

Those details may emerge during future court proceedings.

Meanwhile, the Del Rio community continues mourning a killing that occurred in broad daylight along one of the city’s busiest streets.

Friends have expressed disbelief that such violence unfolded in a highly visible residential area during the middle of the afternoon.

Many have focused their attention on Peña’s five children, who now face life without their mother.

Supporters have described her as a caring parent whose death has devastated everyone who knew her.

As prosecutors prepare their case, investigators continue working to determine precisely why the confrontation turned deadly.

Although arrests have already been made, officials stress that many questions remain unanswered regarding the events leading up to June 25.

For now, authorities say the combination of surveillance footage, witness statements and physical evidence recovered during the investigation provides the foundation of a murder case that will ultimately be decided in court.

Until then, the final images of Caroline Raquel Peña—standing outside a home, smiling as she spoke on the phone only moments before investigators say she was attacked—remain among the most haunting pieces of evidence in a tragedy that has forever changed the lives of her family and the five children she leaves behind.
