KAISERSLAUTERN, Germany — A security forces airman died Monday after being seriously injured in a car crash last month, Air Force officials said.

Senior Airman Christopher Rocha, 23, was a staff sergeant select and an alarm monitor for the 569th U.S. Forces Police Squadron, the 86th Airlift Wing at Ramstein Air Base said Wednesday.

He was from El Paso, Texas.

Rocha died Monday morning at Walter Reed Army Medical Center in Maryland, according to statements from the Westpfalz Police Department and the Air Force.

Rocha had been transferred there following the Aug. 18 crash on a road between Landstuhl and Ramstein.

“Monday we lost a valuable member of our Team Ramstein family,” Brig. Gen. Otis Jones, 86th Airlift Wing commander, said in a statement Wednesday. “Senior Airman Rocha was an important member of our team and will be severely missed by all of us who had the honor to serve alongside him. Our thoughts and prayers continue to be with his family, friends, and co-workers during this time of loss.”

Chaplains and mental health professionals are available to assist those in need, base officials said.

Rocha was injured in a head-on collision. He lost control of his Honda, went into the other lane and hit a Toyota driven by a 49-year-old German citizen from Weilerbach, who was also hospitalized, police said.

The cause of the crash remains under investigation, base officials and Westpfalz police said this week.

At least four U.S. service members have died in traffic crashes in Germany this year. The other three were soldiers stationed in the state of Bavaria.

Two of the soldiers were killed in personal vehicles, and the third was riding in a tactical vehicle.
