An East Coast drifter, who authorities say killed seven people in Connecticut in 2003 while driving a van he called the 'murder mobile', has been sentenced to life in prison.
William Devin Howell, 47, was sentenced to 360 years in prison by a New Britain, Connecticut superior court judge on Friday, after pleading guilty to six of the murders in September.
The Hampton, Virginia, native was previously convicted of manslaughter in the death of one victim, Nilsa Arizmendi, and sentenced to 15 years in prison.
Victims' relatives who spoke during the emotional hearing on Friday had angry words for Howell and described how the killings devastated their lives.
The killer, a native of Hampton, Virginia, apologized in court, saying his acts were 'monstrous, cowardly and selfish'.
Howell is believed to be the most prolific serial killer in Connecticut history - not counting mass shootings like the Newtown school massacre.
