Maine State Police arrested a Standish man Saturday afternoon and charged him with murder in connection with the death of his 3-month-old son, authorities said.

Eugene “Charlie” Martineau, 24, was taken to the Cumberland County Jail after his arrest in Portland about 3:30 p.m., said Stephen McCausland, spokesman for the Maine Department of Public Safety.

Martineau is charged in the death of Leo Josephs, who died Saturday at Maine Medical Center in Portland, according to McCausland’s news release. The mother of the baby is Julia Josephs, 21, of 180 Bonny Eagle Road in Standish.

The baby was brought to the hospital Wednesday and was being treated for multiple injuries. An autopsy will be performed at the state Medical Examiner’s Office in Augusta.

Leo and his twin sister were born prematurely. Authorities said the baby girl is still in the hospital being treated for early birth complications.

A Facebook page for Martineau features a profile photo of a man holding a baby and a cover photo of two small babies, one of whom is attached to medical tubes. The page shows Martineau to be living in Sanford, in a relationship with Julia Kathleen Josephs and as a “cultivator at Marijuana.”

Martineau will make his first court appearance Monday in Cumberland County Superior Court in Portland.

Martineau’s arrest follows other recent deaths of babies in Maine, allegedly at the hands of young men.

Samuel Moore, 25, of Bangor pleaded guilty to manslaughter July 9 and got a 17-year prison sentence after being charged with causing fatal injuries to a 5-month-old girl he was babysitting. He also was charged with allegedly choking the baby’s 3-year-old brother.

Danny Adams, 24, of Lewiston pleaded not guilty in February to charges that he killed his 3-month-old son, after telling police that he had used heroin and marijuana the night before and was frustrated that the child wouldn’t stop crying.

The Cumberland County Sheriff’s Office is assisting state police in the investigation of Leo Josephs’ death.
