SAN DIEGO (AP) — Two men were sentenced to life in prison without the possibility of parole Friday for their roles in a Mexican drug gang that dissolved victims' bodies in acid. Jose Olivera, 38, got five consecutive life terms and David Valencia, 42, got two consecutive life terms for charges including murder and kidnapping. They were the first defendants to go on trial in a case that prosecutors say is one of the worst examples of Mexican drug violence spilling across the border into the United States.
