Authorities are hoping they have the answer to a question that has plagued them since early 2009: Who killed two mother-daughter pairs in a two-month period in suburban Maryland?
Jason Thomas Scott, 27, was charged today in the murder of Delores and Ebony Dewitt, a mother and daughter who were found in a burning car in March 2009. A Prince George's grand jury returned a seven-count indictment against Scott, including two counts of murder and two counts of burglary.
Law enforcement sources told ABC News that they believe Scott also killed Karen and Karissa Lofton two months prior in their locked home.

He has a degree in computer science at the University of Maryland and had worked at UPS. According to law enforcement sources, Scott may have used the company's database to help select victims. He lived close to the Dewitts in Upper Marlboro, Md.

He was arrested in July 2009 in a UPS parking lot after the Bureau of Alcohol, Tobacco, Firearms and Explosives got a tip that he was selling weapons out of the trunk of his vehicle. He was charged with selling 14 stolen guns including pistols, assault weapons, silencers and a machine gun. He remains jailed on weapons and carjacking charges.
