Martin Jiminez, 43, was ordered held without bail today at his arraignment on charges he killed Melissa Hardy, 33, in his apartment late Sunday or early Monday, according to the Suffolk County District Attorney's office, which says that after he killed her, he padlocked her body in his bedroom and took off on a drunken bender in a car belonging to a member of her family that ended when he was stopped and arrested for operating under the influence in Concord.

Prosecutors said Jiminez was so out of it that police immediately brought him to a local hospital for mental-health and substance-abuse evaluations. While there, the DA's office says, he told two fellow patients he had killed his former girlfriend, with whom he'd had an on-and-off relationship for several years, before she left him a few weeks ago to live with her family in Weymouth after he attacked her physically.

Those patients in turn relayed that information to law enforcement. Boston Police conducted a well-being check at Jiminez’ apartment late yesterday and discovered her remains inside Jiminez’ bedroom, which had been padlocked from the outside. Her remains showed signs of physical trauma, and Jiminez was arrested as he attempted to leave the hospital yesterday.
