OKLAHOMA CITY – An Oklahoma City jury has decided on a life prison term for a 67-year-old man convicted of fatally shooting one of his drug runners more than 35 years ago.

Raul Sierra was convicted of first-degree murder for the November 1982 slaying of 23-year-old Wilfredo Roberto Matos Osorio. The case remained unresolved until 2015 when new testing of blood evidence linked Osorio to the house where the shooting occurred.

Investigators say witnesses told them Osorio was killed for skimming money from drug sales and for raping or trying to rape two women.

Sierra denied any involvement. He did not testify at his trial that ended Friday.

The Oklahoman newspaper reports witnesses testified the Bee Gees song “Stayin’ Alive” was played to hide the sounds of the shotgun as Osorio was killed.
