An investigation in the deaths of an East Falls Church married couple has found the cause and manner of death to be ruled homicide-suicide.

The deceased, Maria Theista Macknight, 72, and Gregory Cunningham, 72, of Arlington, died by carbon monoxide poisoning.

The couple was found on Dec. 7 in the 2400 block of N. Powhatan Street of Arlington County after a welfare check was initiated. Officers located the adult male and female deceased inside with signs of intentional carbon monoxide poisoning.

The Arlington Police Department’s homicide and robbery unit initiated a death investigation.

In March, the Office of the Chief Medical Examiner ruled the manner of Macknight’s death a homicide with cause being carbon monoxide poisoning. Cunningham’s death was ruled a suicide with cause being carbon monoxide poisoning.

This remains an active investigation and anyone with information related to this incident is asked to contact the Arlington County Police Department at (703) 228-4180 or [email protected].
