Martin Edward Mullineaux, 62, was found dead in his Columbia, Maryland condominium on September 13, 2016, after failing to show up for work for two days. Police responding to a wellness check discovered Mullineaux on his bedroom floor, the victim of a violent attack that included numerous stab wounds and blunt force trauma to the head. There were no signs of forced entry.

Investigators concentrated on 28-year-old Joseph P. Loverde, a man with no fixed address who had a personal relationship with Mullineaux and had been allowed to stay with him at times. Surveillance showed Loverde using Mullineaux’s credit cards in the days after the killing, and police believed he had the victim’s cell phone and had taken Mullineaux’s Kia Sorento. Loverde was arrested the day after the body was found and charged with murder, assault, and vehicle theft.

Loverde later pleaded guilty to first-degree murder and was sentenced to life in prison with all but 45 years suspended; he must undergo a mental health evaluation and treatment and will face five years of supervised probation upon release. Did anyone who knew Martin or his routines notice anything unusual in the weeks before September 13, 2016?
