A suspect accused of murdering his rock singer friend in 1993 has been apprehended in Central America after spending more than 30 years successfully evading authorities. According to the US marshals service, Richard Werstine, who was wanted in connection with the killing of Cold as Life vocalist Rodney Barger, was arrested in Panama. Investigators say Barger, who was 23 years old, was Werstine’s roommate and close friend when Werstine allegedly shot him in the head as he slept inside their Detroit residence on 15 September 1993. Authorities said Werstine, now 56, was taken into custody at a dog park in Panama City, Panama, on 29 April after decades as a fugitive following the alleged murder of Barger.
