(WDVM/AP/WFXR) — A man serving a life sentence on a murder conviction is now facing additional charges in connection with decades-old investigations into the deaths of two other people from Virginia and Maryland.

According to police, 52-year-old Charles Helem has confessed to the slayings of 37-year-old Eige Sober-Adler in Fairfax County, Va. and 19-year-old Jennifer Landry in Prince George’s County, Md.

Sober-Adler was found dead near a Days Inn off Centreville Road in Herndon. Her vehicle was found in a parking lot near Dulles Toll Road on Sept. 9, 1987, Fairfax County Police said.

“This indictment will not bring her back. And while her parents are not here to experience this day, it is my hope that those who knew and loved her will have some semblance of closure,” said Fairfax County Commonwealth’s Attorney Steve Descano.

Meanwhile, Landry — a Massachusetts resident — was said to be picked up in August 2002 in Washington, D.C. and then killed in Mount Rainier, according to Prince George’s County Police.

Helem is currently serving life in prison after being convicted of strangling his ex-girlfriend, Patricia Bentley, — a 37-year-old single mother from Chantilly, Va. — in 2002.
