Tammy Fox, 38, died on 22 August when her car hit a tree in Scranton, Pennsylvania.
The brakes failed because her boyfriend, John Jenkins, admitted to police that he had cut the brake lines to obtain a metal pipe that could be used to smoke crack cocaine.
Jenkins said he didn’t know anything about cars and just cut off something of the right shape.
He’s now been charged with murder.
