Two U.S. citizens were shot at the border as they were commuting from Mexico to work in Southern California, media reports said Tuesday.

The two were riding in a pickup truck on their way to work at a beverage maintenance company when their assailant opened fire on them in San Ysidro at the border crossing at around 2 a.m., according to the Los Angeles Times. The men had to be at work in San Diego by 3 a.m.

Sergio Salcido Luna, 25, and co-worker Kevin Joel Romero, 28, were shot by a man wielding a 9-millimeter handgun.

The Times reported that Luna was an aspiring mixed martial arts fighter, born in Bakersfield, California.

The Associated Press reported that the two were waiting in line to cross the border when they were shot.

"I was taken back," Matt Pelot, the employer of the two men, said when he heard the news. "I was in shock, and I'm still in shock. These were good guys. Obviously no one deserves to die like this, but these were good guys."

San Ysidro is one of the world’s most busy points of entry in the world. More than 50,000 vehicles pass through each day and 25,000 on foot.
