Police in Prince William County are investigating two separate fatal incidents that occurred hours apart on Friday.
The first incident occurred at the intersection of Yates Ford Rd and the Prince William Parkway at around 4:30 p.m. Investigators say that 47-year-old Brian David Samf was tailgating another driver when both vehicles stopped at the intersection. Investigators say that after the vehicles came to a stop, Samf got out of his 2000 Dodge Dakota and walked toward the other vehicle, a 2012 Ford F-150. As Samf tried to fight the driver of the Ford through the F-150's window, authorities say that the Ford's driver, identified only as a 38-year-old from Manassas, began to move the vehicle forward. At that point, investigators say that Samf fell and was run over by the Ford.
Samf was transported to an area hospital, where he was pronounced dead. The driver of the Ford has not yet been charged. Police say that neither drugs nor alcohol appear to be factors in the incident.
Shortly after 7:00 p.m., police say that 56-year-old Erwin Jose Valdez-Perez, of Woodbridge, was struck and killed by a Mazda while attempting to cross Spriggs Road in Woodbridge. Police believe that Valdez-Perez was attempting to catch his dog, which had escaped and was running across the road. The dog was struck and killed by another vehicle.
Police say that the driver of the Mazda, identified only as a 19-year-old from Woodbridge, was determined not to be at fault and was not charged.
