Roger Mandel Greenberg, 62, of the 11500 block of Seven Locks Road in Potomac, has been charged with first-degree murder by Montgomery County Police.
Police say charges are the result of the murder of Dr. Joyce Hadl, of the 2800 block of Washington Ave. in Chevy Chase.
On Aug. 21, police received a call asking them to check on the welfare of Hadl because she had missed appointments and had not returned phone calls from family members. When police first investigated, they said they did not find Hadl or any evidence of foul play.
"Her car was still parked outside," said Lucille Bauer, spokesperson for Montgomery County Police.
But when police returned they found what they say is evidence that a crime of violence had occurred, and that an attempt had been made to clean the room in order to conceal evidence.
Over the course of the investigation, police learned that Susan Lynn Sachs, 39, of no current fixed address, was a tenant of Hadl, and that the two had been in an argument earlier in the week. Sachs was arrested on Aug. 23 and charged with first degree murder.
Greenberg was taken into custody on Aug. 24. Upon his arrest, police say he complained of mild chest pains, and he was taken to the hospital. After he was discharged from the hospital on Aug. 25, he was taken into custody.
Also on Aug. 25, police obtained a warrant and searched a property on the 4000 block of Ridge Road in Westminster, Md. and arrested David G. Kaufman, 36. Kaufman was charged as an accessory after the fact.
Kaufman lives in Westminster with his father, but the father was not charged.
"No further arrests are anticipated," Bauer said.
Police found a female body buried under a shed on the property in Westminster. The body could not be immediately identified due to the state of decomposition and was taken to the state medical examiner's office in Baltimore.
The medical examiner identified Hadl's body and ruled that the manner of death was homicide and the cause of death was stabbing and blunt force trauma.
All three individuals are being held without bail. Police say the investigation is continuing.
