The U.S. Army serviceman suspected of hitting a Japanese man with a car and killing him earlier this month in Okinawa has effectively admitted his involvement in the accident and is willing to apologize to the relatives of the victim, his lawyer said Friday.

The U.S. military is holding the 27-year-old staff sergeant, who works at the Torii Communication Station, a U.S. Army garrison in the village of Yomitan, over the suspected hit-and-run, which happened in the village.

The serviceman's lawyer, Toshimori Takaesu, quoted his client as saying he thinks he hit the man after being informed by Japanese police investigators that traces of the victim's blood and hair were found on the vehicle.
