A spokesperson with the Harris County Sheriff's Office confirms Louis Santee, 22, and Christian Cavazos,19, are charged with capital murder. A detective tells Eyewitness News this is a case of mistaken identity. The accused shooters are tied to a violent street gang, court records say.
According to investigators, on Sept. 25, 2019, the killers followed the Reyes' purple Dodge Charger as they pulled onto Francitas Drive. The couple was coming home from the hospital around 1:30 a.m. after Rosalba's mother passed away.
Detectives said Santee and Cavazos mistook their Charger for someone else's car -- their intended target.
Rosalba was in the front passenger seat of the Charger, her sister was in the back, and her niece was driving. Ramiro was following close behind in his green pickup truck.
As gunfire rang out, Ramiro was parking his truck in front of the Charger. When he rushed to his wife's side, he was also shot.
On Wednesday, detectives tell ABC13 that Santee and Cavazos thought the purple Charger belonged to a Houston rapper and rival gang member, who goes by the name of Cashout Ace, or someone who may have known him.
Last week, Santee and Cavazos were two of four people charged with shooting and killing two people and hurting seven others, including Cashout Ace, when they showed up to his music video shoot.
According to court records, when being questioned about the music video shooting, one of the four suspects gave a statement on the Reyeses murders, exposing how cold hearted it was.
He told detectives when Santee and Cavazos saw news coverage and realized the wrong people were shot "they were not upset" because they had thought they killed Cashout Ace's grandparents "so they were happy with what they had done."
The music video shooting happened in December 2019, three months after Villarreal's grandparents were murdered.
"I think having faith is very important. I had faith they were going to pay and that day came," Villarreal said.

"It's hard to differentiate at what point it stopped being about music and more about murder," said Chris Handley, the chief prosecutor of the Organized Crime Division at the Harris County District Attorney's Office, during an interview with ABC13 last week.
Court records say the gang that Santee and Cavazos are tied to is linked to at least 54 violent crimes over a three-year period. They are allegedly responsible for committing murders, shootings, aggravated assaults and more.
"We hope today, and with the cases filed, it's the first step to tell this gang, 'You can't get away with everything. You will be held accountable,'" said Handley.
