PHILADELPHIA -

Two men will face more charges following the death of the mother of three children who were killed when a sport utility vehicle that police said was carjacked crashed into a group on a corner in north Philadelphia last month, prosecutors said Friday.

The Philadelphia district attorney's office said an additional murder charge will be filed against Cornelius Crawford, 23, and Johnathan Rosa, 19, following the death of Keisha Williams, 34, Thursday night at Temple University Hospital.

Both men were charged earlier with murder, kidnapping, conspiracy, robbery, aggravated assault and sexual assault in the July 25 crash that killed Keiearra Williams, 15; Thomas Joseph Reed, 10; and Terrance Moore, 7, as they were selling fruit for a church fundraiser.

Their funerals were held Monday.

Authorities allege that the defendants carjacked a real estate agent after a house showing, then plowed into the group at an intersection about a mile away.
