PROVINCETOWN – The cold case murder of Ruth Marie Terry, also known as the "Lady of the Dunes," has officially closed with investigators saying her husband, Guy Muldavin, killed her in 1974.

Muldavin died in 2002.

Detectives learned that Terry and Muldavin were married in either 1973 or 1974 and traveled for their honeymoon in the summer of 1974.

The Cape & Islands District Attorney's office said Muldavin returned from the trip and was driving Terry's car. Muldavin told witnesses that Terry had died.

According to Terry's family, Muldavin only said they had a fight during their honeymoon and he had not heard from her again.

Muldavin was also a suspect in the deaths of his previous wife and a stepdaughter in Seattle in 1960.

"Based on the investigation into the death of Ms. Terry, it has been determined that Mr. Muldavin was responsible for Ms. Terry's death in 1974," the DA's office said in a statement on Monday as they announced the case was closed.
