The Japanese man who confessed to shooting a U.S. sailor in Hiroshima in October goes to trial Jan. 9 on attempted murder charges, officials confirmed this week.

Tomoyuki Matsumoto, 37, who police say is a former organized crime syndicate member, turned himself in shortly after the attack and confessed to shooting Petty Officer 3rd Class Eric S. Heinze, 21, a preventative medicine corpsman assigned to Iwakuni Marine Corps Air Station.

Heinze, who recovered fully after surgery in a Hiroshima hospital, has returned to the States.

Police said Matsumoto shot the sailor Oct. 26 as he was walking with two friends in Hiroshima’s Nagarekawa District, a popular nightlife area, because the trio walked in front of his car.

Matsumoto also faces charges for illegal possession of a firearm and for use of an illegal stimulant, said a spokesman from Hiroshima’s District Prosecutor’s office.

A Hiroshima police spokesman said Wednesday that Matsumoto was a former member of an organized crime syndicate in Hiroshima.

“He told investigators that he had been ‘excommunicated’ about a week before the incident, but it still was not clear whether he was ousted before or after the shooting for causing the trouble," the spokesman said.

Base investigators assisted the Hiroshima police, said base spokesman Capt. Stewart Upton.
