Victim Tammy A. Fox, 38, the mother of five children, died when her Hyundai Sonata accelerated, sped through an intersection and slammed into a tree on Aug. 22, according to NJ.com.

Her boyfriend, John Williams Jenkins Jr., 39, allegedly cut the lines "in an attempt to obtain a metal pipe that could be used to smoke crack cocaine," NJ.com reported, quoting the Pennsylvania State Police.

The news site also reported that investigators made the discovery after inspecting the vehicle.

Jenkins, who was arrested and charged with homicide in Fox’s death, is jailed without bail.

His preliminary hearing in the case is scheduled for next week.
