The mother of three children killed when a carjacked vehicle plowed into a crowd of pedestrians in Philadelphia has also died, and the two suspects in the case will now face a fourth murder charge, prosecutors said.
Keisha Williams, 34, died at Temple University Hospital on Thursday night. It was nearly two weeks after she and her three children were struck by an out-of-control vehicle that had been carjacked only moments earlier, according to a statement issued by the Philadelphia district attorney's office.
"The thoughts and prayers of my office continue to be with everyone affected by the senseless crimes that occurred," Dist. Atty. Seth Williams said in a statement. "I hope the knowledge that I am prosecuting these defendants to the fullest extent of the law will give the family some sense of justice during this time of unimaginable grief."
