US citizen killed by Border Patrol after rushing across border from Mexico, shooting at agents

A U.S. citizen has been killed by Border Patrol agents after he tried to force his truck through a border checkpoint and reportedly opened fire at agents.

What happened?

The unidentified suspect was a 23-year-old white male who attempted to cross the U.S. border from Tijuana, Mexico, into San Diego near the San Ysidro Port of Entry around 7:30 p.m. Monday. Border Patrol attempted to stop him at a secondary vehicle inspection site but he refused to comply.

According to a news release from the San Diego Police Department:

[T]he suspect was driving through the Port of Entry from Mexico into the United States. He refused to stop for the CBP Officers and attempted to drive through the inspection area. Several CBP Officers attempted to stop the suspect, whose vehicle was eventually blocked by another vehicle. The suspect began firing a gun out of his vehicle towards the officers, then exited his vehicle and continued firing at the officers. The officers returned fire, striking the suspect.

Rapid fire gunshots can be heard in a video obtained by KNSD-TV (San Diego's local NBC affiliate) that appears to show the incident.

While the suspect's name has not yet been released, police confirmed that he was a U.S. citizen.

What else?

No members of U.S. Customs and Border Patrol were injured during the confrontation. Rescue crews tried unsuccessfully to save the suspect after the shooting.

The San Diego Police are currently conducting an investigation into the shooting. It is not clear if the shooter had a motive.

Customs and Border Patrol told ABC News that the shooting held up border crossings for about 30 minutes.
