BELFAST — A Maine man accused of shooting a Florida firefighter in the head in a drug-related dispute has been indicted on murder charges.

The indictment was handed up this week by a grand jury in Waldo County. Daniel Porter was already being held without bail on a murder charge.

Porter was arrested Feb. 28 at a rented house in Jackson where police say he killed the 31-year-old Jerry Perdomo of Orange City, Fla. Porter told police that he owed Perdomo $3,000 and police said threats were exchanged.

The Bangor Daily News says police arrested Porter after discovering skull fragments and blood drops in the Jackson home. Perdomo’s body was found the next day on property belonging to Porter’s family in Newburgh.
