Houston Police say Palacios was running from police when his pickup truck struck the car carrying Valero and her prom date.
Prosecutors allege his blood alcohol was almost double the legal limit.

Valero died at the scene of the violent crash, while her date was transported the hospital for surgery. He survived the wreck along with Palacios, who only had minor injuries.
Just down the street from the courthouse, Valero's classmates are getting ready for college signing day. She was supposed to be there, too.
"We were best friends, we knew everything about each other. It's kind of hard for us to be here today because we both wanted her to be here," said Valero's classmate, Olivia Carlos.
The victim's sister and cousins described the teen as having a big smile and an even bigger heart.

Valero was nominated for prom queen by classmates at Yes Prep North Central campus.
"She had a bright future ahead of her," Valero's sister Analisa Valero says. "This isn't fair. I'm angry. I wanted to see her get married, I wanted to see her have kids."
Palacios is charged with murder and evading arrest. Palacios got bond conditions, but not bond was set today because a visiting judge presided.
