A man who allegedly murdered his mother in Maryland was connected to the cold case killings of three men, police said.
On Aug. 28, officers performing a wellbeing check on 71-year-old Johnetta Wormley found her dead from traumatic injuries in her Temple Hills home.
On Sept. 1, authorities arrested the woman’s son, John Frederick Carrington, 53, and charged him with the murder of his mother, D.C. station WTTG reported.
Police also charged Carrington with an Aug. 28 non-fatal domestic-related stabbing as well as the attempted robbery of a gas station on Aug. 30.
One day after his arrest, authorities from the Metropolitan Police Department announced Carrington also now faces three additional charges in connection to a series of cold cases spanning almost 20 years.
Early in the morning of Aug. 30, 1992, police found 29-year-old Charles Boulware, of Northwest, D.C., suffering apparent stab wounds and he later died from his injuries.
Almost 16 years later, on March 15, 2008, police in D.C. found 42-year-old Reginald Gaither, of Alexandria, Virginia, dead in his car from a gunshot wound.
On Dec. 10, 2010, 25-year-old James Campbell, of Bladensburg, Maryland, was found fatally shot in D.C.
For those crimes, Carrington is charged with two counts of first-degree murder while armed and one count of felony murder.
Police have not revealed how they connected Carrington to the three cold-case murders.
