RAYMONDVILLE, Texas (AP) - A South Texas sheriff says a gun’s been found that may be the weapon used to kill an off-duty Border Patrol agent shot while fishing with his family earlier this month.

Two men from Mexico are held without bond and face capital murder and other charges after 36-year-old Agent Javier Vega Jr., of Kingsville, was fatally shot and his father wounded during an attempted robbery.

Willacy County Sheriff Larry Spence tells The Monitor of McAllen (http://bit.ly/1v0SLZH ) the gun was found outside a home where 30-year-old Gustavo Tijerina and 40-year-old Ismael Hernandez were arrested Aug. 4. A man cutting grass at the house spotted the weapon and called police.

Spence says investigators also are analyzing shell casings from the shooting scene. A preliminary investigation showed Vega’s mother may have returned fire.
