The Maine State Police are still investigating the cause of death Saturday of a 3-year-old Howland boy.

The state Medical Examiner’s Office said Monday that it conducted an autopsy on the boy the office identified as Justin Jenkins Jr., according to information provided to WMTW-TV.

State police were notified of the boy’s death around 6:39 p.m. Saturday by the Penobscot County Sheriff’s Office. All deaths of children 3 and younger are investigated by the State Police Major Crimes Unit, but the agency did not release any additional information Monday.

The Bangor Daily News reported that the boy’s father, Justin Jenkins, 38, of Howland made his first court appearance Monday via Zoom from the Penobscot County Jail. Justice Ann Murray ordered him held without bail after he was arrested on three charges of violating conditions of his release.

Murray issued her order after Assistant District Attorney Mercedes Gurney told the judge that Jenkins had a no-contact order with a Howland woman – the mother of the dead boy – and that Jenkins violated that order when he was “present” during his son’s death on Saturday, the Bangor Daily News reported.

Gurney said the boy’s mother brought him to Penobscot Valley Hospital in Lincoln, where he was pronounced dead. The woman told police that Justin Jenkins was present when their son died.

Jenkins has not been charged in connection with the boy’s death.
