PRINCETON, Mass. (WHDH) — A prominent dentist from Princeton has been indicted by a grand jury in the death of his wife Friday afternoon.

The Worcester District Attorney’s office has confirmed that Roger Desilets has been indicted on charges of manslaughter and assault and battery for the death of his wife. Kathleen Desilets, 65, was found near death beneath a broken third floor window in Dec. 2011. She was then taken to a hospital where she died.

The suspect will be in Worcester Superior Court on January 2 for an arraignment.

Desilets told police who responded to his 911 call that he and his wife had been fighting ever since she learned that he had been unfaithful. According to testimony, on the night she died, the couple had fought twice, once after she found out he was tracking her calls to see if she was having an affair.

Edward Ryan Jr., the defense attorney on the case, claimed that after she discovered the phone bills, “she came downstairs and physically attacked him and gouged his face and broke his glasses.”

The grand jury had learned that the dentist had dried blood marks on his face where she allegedly attacked him.

The second time they fought it was because he had made a sexually-demeaning remark. Desilets reported that his wife then went up to the third floor. He later heard noises and found that his wife had smashed out the window with a chair. He said she fell out possibly intentionally.

Ryan said Friday his client "had absolutely no role" in his wife's death and called the indictment another tragedy. He said he is very disappointed in the grand jury. He said Desilets will be vindicated.
