A woman has been shot to death in Fort Worth overnight.
Just before 11 p.m. a 911 caller told police the mother of her son's friend had been shot in the head.
Police and paramedics rolled to a home on Mason near I-35 and Seminary. They found the woman -- already dead -- in a car pockmarked with bullet holes.
Detectives are not saying why she was shot -- or who did it.
