A Marine killed in an aircraft crash Wednesday in Imperial County, California was identified as a son of ex-Los Angeles Dodgers great Steve Sax.

Capt. John J. Sax, 33, was one of five Marines killed when their Osprey tiltrotor aircraft went down during a training exercise roughly 20 miles northeast of the city of Holtville.

“It is with heavy hearts that we mourn the loss of five Marines from the Purple Fox family” the squadron’s commanding officer, Lt. Col. John C. Miller, said in a statement, ABC7 Los Angeles reported.

“Our primary mission now is taking care of the family members of our fallen Marines and we respectfully request privacy for their families as they navigate this difficult time.”

The marines, who were based in Camp Pendleton, had been engaging in a live fire exercise in the remote unincorporated community of Glamis.

The cause of the accident remains under investigation.

The victim’s dad played in the Major Leagues from 1981 to 1994, winning two world championships during his seven years with the Dodgers.

The Hall of Fame candidate also played with the Yankees from 1989-81, and later had brief stints with the Chicago White Sox and Oakland Athletics.
