The teenager arrested in the Mexican state of Morelos in 2010 for belonging to the Pacifico Sur drug cartel and participating in several murders was released from a reformatory Tuesday after completing his sentence and is being deported to the United States, officials said.

Edgar Jimenez Lugo, a 17-year-old known as "El Ponchis" (The Cloak), was released in the early morning hours and "is being transferred to the United States, his country of origin," Morelos Government Secretary Jorge Messeguer said.

"(It was in the) interests of the government of Morelos that Edgar 'N,' known as 'El Ponchis,' have better conditions because he too was a victim," Messeguer said in a Twitter post.

Prison service officials in Morelos, which is in central Mexico, and Cempla, the agency that oversees young offenders, refused to comment on the case.

National Migration Institute, or INM, agents confirmed that the San Diego-born teen had the necessary documents to travel to San Antonio, Texas, media reports said.

Jimenez Lugo was arrested by army troops along with two of his sisters at the airport in Xochitepec, Morelos, when he tried to catch a flight to the United States in December 2010.

The boy, who was just 14 at the time, planned to fly to Tijuana, a border city in Baja California state, cross the border and head to San Diego.

Jimenez Lugo, who became involved with drug traffickers at the age of 11, told investigators that he beheaded four men on the orders of a cartel boss.

A judge sentenced Jimenez Lugo to three years in prison a few months later after convictions were handed down on murder, organized crime, kidnapping and drug charges.

The Pacifico Sur drug cartel was created by former members of the Beltran Leyva gang. EFE
