The human remains of a Cutchogue woman who went missing in 1966 may have been discovered in the basement of a Southold home.

The family of Louise Pietrewicz says that at the time she went missing, she was having an affair with a married Southold police officer, William Boken, who lived in the home on Lower Road.

Suffolk police had to dig 6 feet underneath concrete in the basement to find the remains. The current homeowner didn't want to speak to News 12, but allowed a camera into the basement.

Police say they had previously searched the basement in 2013, but responded to a much more specific tip this time around. They were able to find the remains using a sonar machine.

“It is nice to be able to bring closure to the family. No missing person case is ever resolved until you find the body or arrest the murderer,” says Chief Gerard Gigante.

Boken's wife divorced him before he died in the 1980s. News 12 couldn’t reach her for a comment about the discovery.

Pietrewicz’s surviving sibling, 93-year-old Leo Jasinski, got the news Monday night that his sister may have been found. He believes Boken's wife knew about the alleged murder, but didn't say anything about the dark secret until after she learned about her ex-husband’s death.  

“Boken’s wife wouldn't give no information because she was afraid for her life,” said Jasinski.

Police did not confirm that Boken’s wife was the tipster.

Jasinski says he’s finally beginning to process the news of the discovery.

“It's a relief to find out that she's been found and that we can have a decent burial for her,” he says.

Authorities have taken DNA from Pietrewicz’s family and will soon determine the identity of the remains.
