Father Blamed for Family Murder A Virginia man is believed to have killed his wife and two sons in a murder-suicide at their home in Virginia, police said today. The bodies of Albert and Kathleen Peterson and their sons were found Tuesday morning by police performing a welfare check on the family after one of the adults did not show up to work for two days. Today, Fairfax County police said that the investigation is now pointing toward Albert Peterson, 57, as the killer. All four members of the Peterson family received gun shot wounds to their upper bodies, according to a statement released by the police. "The preliminary investigation indicates that Albert Peterson killed his wife and their children before taking his own life," the Fairfax County police said in a statement. Kathleen Peterson, 52, worked for defense contracting firm Blackbird Technologies in Herndon, Va., where the couple lived. Albert Peterson had worked for Northtrop Grumman until he resigned in 2009. It is not clear where he was working at the time of the incident. The couple had two children: Matthew, 16, a high school sophomore, and Christhoper, 13, who was in eighth grade.
