WORCESTER — A Worcester dentist has been indicted on manslaughter and assault charges in the 2011 death of his wife at the couple's Princeton home.

A Worcester County grand jury handed up indictments Friday charging Roger P. Desilets Jr., 69, with manslaughter and assault and battery in the death of 65-year-old Kathleen M. Desilets, whose body was discovered in the early morning hours of Dec. 6, 2011, beneath a shattered third-floor window at their home on Worcester Road.

He is scheduled to be arraigned Jan. 2 in Worcester Superior Court.

Desilets died of blunt trauma of the torso with a laceration of the heart and fractures of the ribs and spine, according to a death certificate.


Roger Desilets told Princeton police who responded to his 911 call that morning that he and his wife had gotten into an argument and that she threatened to jump out of a window.

Desilets said he and his wife of 44 years made up, but that another argument ensued after he made an "off-color" or "sexually demeaning" remark to his wife.

He said she put on her robe and went upstairs to another bedroom.

Later, after hearing noises, Desilets said he went upstairs to find Kathleen Desilets smashing a window with a chair. Desilets related to police that his wife went through the window, either intentionally or as a result of the momentum of breaking the window.
