Denise Bozarth, accused of bludgeoning her husband to death aboard a Key Largo houseboat in 2007, has been formally indicted by a grand jury on a count of premeditated murder.

Bozarth, 39, remains in custody in the Monroe County jail with no bond allowed. She was arrested in March after an investigation lasting nearly five years.

Assistant State Attorney Theresa Hunnewell presented evidence to the grand jury in a one-day session last Friday at the Plantation Key courthouse.

The body of Edward Bozarth, 62, was discovered in July 2007, stuffed into a canvas sack concealed inside the engine compartment of his boat, named Screw U 2, docked at Gilbert’s Marina.

Edward Bozarth had been killed by “blunt force trauma to the head” about a week before the grim discovery, the Monroe County Medical Examiner’s Office concluded.

The couple had been married for nine years and had two children.
