VERNON, Vt. (AP) — The office of the Vermont Medical Examiner says the only suspect in a double murder in New Hampshire last month died of acute drug intoxication.

The Brattleboro Reformer reports the death certificate for Derrick Shippee, of Westmoreland, New Hampshire, says he died of a mixture of cocaine, heroin, fentanyl and acetyl fentanyl, and that he died in a matter of minutes.

The death certificate ruled his death was accidental.

Shippee’s body was found in a field owned by his family in Vernon on April 12, a day after the bodies of 29-year-old Neal Bolster, of Hinsdale, and 19-year-old Aaliyah Jacobs, of Brattleboro, were found at Bolster’s Plain Road home in Hinsdale. An autopsy showed both died of gunshot wounds.
