A Connecticut man accused of retaliating for a drug debt by setting a fire that killed an 8-year-old boy and two women has been sentenced to life in prison.

Twenty-nine-year-old Hector "Boom Boom" Natal, of New Haven, was sentenced Wednesday in federal court. A jury convicted him in April 2013 of arson resulting in death.

Prosecutors say Natal set fire to a multifamily home in New Haven in 2011 as 17 residents were sleeping. Three people died: 42-year-old Wanda Roberson, her 8-year-old son, Quayshawn, and her 21-year-old niece, Jaquetta Roberson. Authorities say Natal set the fire in a drug dispute with another person in the building.

Natal's father, Hector Morales, was sentenced last month to 14 years in prison for serving as Natal's getaway driver.
