During an initial investigation, authorities learned that a Border Patrol agent was on patrol on an ATV in the area of Spooner’s Mesa when he was hit with a rock and knocked off the vehicle by Alvarado.
The suspect rode away on the ATV and was chased by several other agents before losing control and crashing into a fence.
During the chase, both agents reportedly shot at Alvarado, striking him at least once. Alvarado is being charged with assaulting a federal officer. The San Diego Police Department is handling the investigation.
