AUBURN, Maine — Two more men have been charged in connection with the death of a Lewiston man in Greene last month.

Nathan Morton was arraigned Thursday morning in Androscoggin Superior Court on charges of murder, conspiracy to commit murder and hindering apprehension or prosecution in the death of 20-year-old Romeo Parent in April.

William True Jr. also was arraigned, on a charge of Class B hindering apprehension or prosecution.

Both men pleaded not guilty. No other information was available on the men Thursday morning.

Last month, Michael McNaughton, 23, was charged with murder in connection with Parent’s death. Investigators at the time said the killing was committed because McNaughton believed Parent was a police informant.

On Thursday morning, McNaughton was arraigned on charges of murder, conspiracy to commit murder and hindering apprehension or prosecution. He also pleaded not guilty.

McNaughton, who has no criminal convictions, has been held without bail at the Androscoggin County Jail since his arrest April 12.

Police have said Parent was killed late on the night of April 9. His body was found three days later in Jug Stream, just below the dam that separates Annabessacook and Cobbosseecontee lakes in Monmouth.

Detectives believe Parent was killed near South Mountain Road in Greene and that his body was dumped into the stream along Route 135 the next day.

Parent and McNaughton knew each other, investigators have said. They were friends, but McNaughton had come to believe that Parent had provided information to police about earlier criminal matters.

Parent attended Lewiston High School and worked at an area Dunkin’ Donuts. He had lived at 23 Howe St. in Lewiston but was described by police as a transient.

The charges against the three men came on the same day a bail hearing was being held for McNaughton. The hearing is expected to take up much of the day.
