Humberto Chapetti, 18, was arrested for his involvement in the murder of Romulo Barcarse, 29, the Tucson Police Department said in a news release. 

Chapetti was being held in Pima County Jail on unrelated charges when gang detectives located him, the news release said. Chapetti faces charges of first-degree murder, abandonment or concealment of a dead body and prohibited posessor. 

Barcarse's remains were found on a ranch on the 12900 block of South Old Nogales Highway on August 14.

Bacarse was identified by an acquaintance through social media a few days after Tucson police released information to the public about his tattoos in hopes of identifying his remains.
