TUCSON, Ariz. — The scheduled start of the trial of a U.S. Border Patrol agent charged with second-degree murder in the cross-border shooting of a Mexican teen is being delayed to accommodate the defense lawyer’s work schedule.

U.S. District Raner C. Collins on Thursday granted a request to delay Agent Lonnie Swartz’s trial to Oct. 24 from Oct. 12.

Swartz is accused of firing through the border fence from Nogales, Arizona, into Nogales, Sonora, Mexico, and striking 16-year-old Jose Antonio Elena Rodriguez about 10 times.

Swartz said Elena Rodriguez threw rocks at him, endangering his life. The boy’s family has denied that, saying he was walking home after playing basketball with friends.

The rescheduling motion said defense lawyer Sean Chapman will be finishing a trial in another case shortly before Oct. 12.
