A 29-year-old Parkville man with a history of psychiatric problems was charged last night with first-degree murder in the death of his mother, a multiple sclerosis patient who used a wheelchair, police reported.
David Raymond Lorenz was charged in the death of Jean Blanche Lorenz, 57, with whom he shared a residence in the 8800 block of Wilson Ave., said Sgt. Stephen R. Doarnberger, a Baltimore County police spokesman.
Paramedics went to the one-story cottage about 1 p.m. yesterday after a call from the victim's sister, Sergeant Doarnberger said. The sister made that call after herself receiving a call from Ms. Lorenz, Sergeant Doarnberger said. He said that the sister had thought that assistance was required because of a fall from a wheelchair, the sergeant said.
When paramedics arrived, they found the door locked and could not enter, Sergeant Doarnberger said.
When officers arrived, the door was opened by the son, police said.
Ms. Lorenz -- who had been decapitated -- was found lying in the hallway, police said.
The son was arrested, Sergeant Doarnberger said.
Neighbors said the family had lived in the home for at least 20 years.
Neighbors said Ms. Lorenz had a male companion who picked her up at least every other day and took her to the doctor's office and other places.
Otherwise, they said, she tended to stay to herself.
The victim was described as divorced with a daughter and a grandchild, in addition to the son.
Sergeant Doarnberger said Mr. Lorenz has a history of psychiatric problems and was released in December from the Sheppard and Enoch Pratt Hospital.
Police records indicated that officers had been summoned to the home in October 1987 to pick up Mr. Lorenz for an emergency psychiatric evaluation, Sergeant Doarnberger said.
Fred J. Geary, a next-door neighbor, said the victim was diagnosed with multiple sclerosis about 10 years ago.
"She tried to get on as best she could; she was a fine woman," Mr. Geary said.
Her son was being held last night at the White Marsh precinct, police said.
