Baltimore County police have arrested a 27-year-old man after a grand jury charged him in connection with the slaying of his parents at their isolated home near Patapsco State Park.
John George Dietz III was taken into custody without incident about 3 p.m. yesterday at the home in the 7700 block of Inwood Ave. near the Ellicott Mills neighborhood, police said.
Dietz, who took up residence at the horse farm property there after the deaths of John George Dietz Sr. and Lillian Ann Dietz, both 63, is charged with two counts of first-degree murder, burglary of the home and robbery, police said.
Dietz was held without bail at the Baltimore County Detention Center, pending a bail review hearing in Towson District Court today.
The grand jury indictment was handed down Monday, police said.
A family friend who lives on the property called police early Oct. 29 after becoming alarmed when the couple failed to answer her knock.
About 1:45 a.m., police officers arrived and found the bodies of the couple in their bedroom, dressed in night clothes. Each had been shot in the head. John Dietz Sr. was lying on the floor and Lillian Dietz was on the bed.
From the beginning, police said they thought the assailant knew the couple because of the lack of forced entry or ransacking, and the isolation of the home, which is hidden by woods near the state park and Interstate 70 in the western part of county.
