MEXICO CITY (CNS) – An outspoken Argentine priest known for denouncing the threat of drug trafficking and warning of rising crime in the northern part of the country was found hanged in his parish home.

The circumstances of Father Juan Heraldo Viroche’s death remain uncertain.

Investigators told local media there were no signs of violence or “something that would suppose there was some kind of altercation with someone.”

But Father Viroche, 47, had a history of speaking out on security issues and drug dealing.
