Nineteen years after her daughter's murder, a mother hopes the killer is caught in an Arizona cold case.
"I died with her that day, and it's taken years to even snap back," Tamara LaRue told ABC15.
A driver found the body of LaRue's 20-year-old daughter Rebecca Rubalcava, and 39-year-old William Rodriguez, in April 1999 off State Route 93 between Wickenburg and Kingman.
The Yavapai County Sheriff's Office said both were shot multiple times in the head.
"As a mother, we protect our children, and I wasn't able to do that for her," LaRue said.
She didn't know Rodriguez, but said her daughter recently escaped human trafficking and was living on her own near 17th Avenue and Buckeye Road.
Yavapai Silent Witness recently teamed up with Phoenix Silent Witness to spread awareness in the Valley and bump the reward in the case to $10,000 for tips leading to an arrest.
LaRue said the pain following her daughter's death prompted her to leave the state several years ago, but she has renewed faith justice will come.
"I just need everyone's help," LaRue said. "I know someone out there knows something."
