(Newser) – A notorious hit man in Mexico known for beheading his victims and displaying them in public is a US-born kid all of 14 years old, reports AP. Mexican authorities arrested the youth identified only as Edgar—who they say goes by "El Ponchis," or the cloaked one—as he tried to leave the country by plane. He said he's worked for a cartel since he was 11, after being kidnapped. "I participated in four executions," he said, "but I did it drugged and under threat that if I didn't, they would kill me."

He carried two cell phones with photos of tortured victims, say police, who also arrested an older sister accused of helping him dispose of corpses. Mexican authorities say the youth is a native of San Diego, though his US citizenship remains unconfirmed. Rumors of the young hit man emerged about a month ago with a YouTube video that showed teens mugging for the camera next to corpses. One of them named "El Ponchis" as an accomplice.
