On January 26, 2009, 16-year-old Karissa Olivia Lofton and her 45-year-old mother, Karen Lofton, were found shot to death inside their home on Southall Drive in Largo, Maryland. Karissa placed a whispered 911 call shortly after 2 a.m., reporting that an intruder had shot both her and her mother; when police entered the house through an unlocked window they found both victims had died in the upper portion of the home.

Detectives initially found no signs of forced entry and nothing missing from the residence, and a lack of forensic evidence hindered the early investigation. In the weeks that followed, investigators noted similarities with other mother-and-daughter killings in Prince George’s County and began to link the case to a pattern of violent crimes.

A nearby resident, 27-year-old Jason Thomas Scott, was later arrested on multiple violent charges and ultimately entered an Alford plea in 2013 for the murders of Delores and Ebony Dewitt; prosecutors did not charge him in the Lofton killings as part of that plea agreement. Does anyone in the Largo community have information about Karissa or Karen Lofton that could still help clarify what happened that night?
