Marie Johnson pleads guilty to killing Elmer Roehrs

A 45-year-old woman accused of killing an elderly Alexandria man who was found dead in his Del Ray home has pleaded guilty Thursday.

Marie Johnson, 45, has pleaded guilty to second degree murder in connection with the death of 94-year-old Elmer Roehrs. Roehrs was found slain in his home in February in the 2700 block of Holly Street.

She is scheduled to be sentenced on Aug. 22.

Authorities say Johnson tried to start a fire at Roehrs’ house after the killing and was seen on surveillance footage entering and leaving the home.

Roehrs’ family says the 94-year-old was restricted to his home. He was a fan of the Orioles, the Redskins and Wizards and watched the teams play on TV. He fixed meals for his wife, cared for plants and always had a cheerful greeting for people, his family says.
