“These people stepped in and helped him out and this is how he repaid them,” Deputy District Attorney Yvette Guthrie said during the sentencing hearing on Nov. 12. “He stole two lives and forever changed their family. Nothing will ever bring these victims back, but I think justice in this case is two consecutive life sentences.”

Deputies were called to the home after Ruben’s sister said that she couldn’t get ahold of her brother for several days. When deputies arrived, they found Deborah on the flood, dead, covered by a blanket. Both victims had been beaten with a pipe and both died of blunt force trauma to the head.
