Following Contreras’ sentence, Castillo’s family held a vigil in honor of the victim outside the Hidalgo County Courthouse.

“I believe he's here with us in spirit,” Castillo’s mother — Joanna Martinez — said. “It was a long journey — five and a half years — but with the grace of God we were able to pull through."

Martinez said her faith gave her strength.

“All I can say is that prayer is very, very powerful," Martinez said."Because two, three years, months ago, I wouldn't be able to stand the way I'm standing — I wouldn't even pass around the courthouse."

Contreras will begin his sentence immediately. He'll be eligible for parole after serving 30 years.
