WORCESTER – A Shrewsbury man pleaded guilty to a charge of involuntary manslaughter in connection with the 2018 killing of a woman in Worcester, according to Worcester County District Attorney Joseph D. Early, Jr.

Joseph Dalrymple, 37, was sentenced to serve 18 to 20 years in prison for killing 38-year-old Marlene Bleau. Dalrymple pleaded guilty in Worcester Superior Court today.

Bleau was discovered on July 28, 2018, face-down in the water in a section of Lake Quinsigamond around Lake Avenue. An autopsy showed Bleau died as a result of mechanical asphyxia.

An investigation by Worcester police detectives identified Dalrymple as the last person seen with Bleau the night before her body was discovered. Authorities located surveillance video and collected witness statements as part of the investigation.

The case was prosecuted by Assistant District Attorneys Courtney Sans and Lina Pashou. The Victim Witness Advocate was Marie Deyette.
