Pr. William Crash Kills Boy, 2, and Woman, 60

A 2-year-old Northern Virginia boy and his 60-year-old grandmother were killed early Friday in Prince William County when the car they were riding in was struck from behind, county police said.

Police said the driver of the other car was arrested and charged with driving under the influence.

The toddler was identified as Jonathan Wade-Ortiz; police said he was in a safety seat in the rear of a Saturn driven by his mother, who was identified only as a 43-year-old woman from Dumfries.

The grandmother was identified as Rebecca L. Sacra of Alexandria. However, it appeared last night that she might have been a Prince William resident.

Sacra was in the front passenger seat of the Saturn, next to her daughter, police said.

A 12-year-old boy in the Saturn had non-life-threatening injuries, police said.

According to police, the crash occurred before 1 a.m. at Prince William Parkway and University Boulevard. After being struck, the Saturn was forced from the road. It went through a fence and across a field before coming to rest on boulders.

Police identified the driver of the other car, a Ford Explorer, as William J. Mallory, 26, of Stafford, Va. He was being held without bond Friday. A court date has been set for November, according to a police news release.
