A military court convicted the Navy commander who recruited Navy doctor Donal Billig of dereliction of duty, lying and perjury, the Navy said. Cmdr. Reginald Newman, 57, faces a maximum of 20 years and six months in prison, dismissal from the Navy and forfeiture of all pay and allowances. He has been in the Navy for 35 1/2 years. Billig, who is charged with manslaughter in the deaths of five patients, is on trial at a separate court-martial charged with five counts of involuntary manslaughter in the deaths.
