DALLAS – An arrest affidavit obtained by FOX 4 reveals that a father and son who were killed in a Dallas triple murder were not the intended targets.
The suspects, who were arrested the same day as the crime after reportedly fleeing to Houston, are believed to have been following the third victim prior to the incident.

The backstory:
Early in the morning of Oct. 12, Dallas police responded to a shooting in West Dallas off Bernal Drive. Three people were found dead, including father and son, 47-year-old Pedra Lara Roa and 21-year-old Pedro Lara.
A third victim, whom police have not identified, was found inside a white van, crashed out on Lara’s front fence.
28-year-old Jimy Caceres Leiva and 23-year-old Brayan Pineda Ayala were both booked on Tuesday morning in the Montgomery County Jail, just north of Houston, and charged with capital murder of multiple people.

Dallas triple murder update
What’s new:
The suspects are now known to have immediately taken off to Houston the day of the triple murder, where they were stopped by DPS troopers. The two suspects in the car were accompanied by two women and a child. The women have been taken into ICE custody.
The two capital murder suspects have been booked into the Dallas County Jail after being transferred from Montgomery County.
Flock cameras captured Leiva’s Chevy Malibu following a white van, which was later found crashed outside a West Dallas home. Why the van’s driver was pursued and killed is still unknown.

The Malibu is seen on camera leaving the scene after the shooting, later arriving in the Houston area.
The newly obtained arrest document confirms a theory previously held by the family of two of the victims: the Laras had left their home to check on the van’s occupant, ultimately leading to their murders as casualties in the crime.
In an interview after their arrests, Ayala allegedly told detectives he supplied the guns, and Leiva shot and killed the three victims. Three guns were found in the vehicle the men were arrested in.

What they’re saying:
In a previous interview with FOX 4, family member Josue Lara said his father and younger brother were likely attempting to help the van driver.
“I don’t know them. I didn’t recognize the guy in the van. I know my dad and brother didn’t know them. They were just trying to help,” said Josue.
“They heard a loud crash. They went outside to try to help, maybe call the cops. They didn’t know if the driver was injured. That’s all that happened. They were asleep.”
