WORCESTER, Mass. (AP) — A Massachusetts man blamed with causing the death of a state police trooper has been convicted of manslaughter.

David Njuguna was found guilty Tuesday by a judge of involuntary manslaughter in the March 2016 death of Trooper Thomas Clardy.

Judge Janet Kenton-Walker cleared Njuguna of OUI manslaughter and felony motor vehicle homicide because prosecutors hadn’t proved he was high on pot at the time of the crash.

Prosecutors say the 33-year-old Webster man was speeding and high on pot when he struck Clardy’s stopped cruiser on the Massachusetts Turnpike in Charlton.

The defendant’s lawyers say he had some sort of medical issue that caused a seizure and made him lose control of his vehicle.


Njuguna faces sentencing Nov. 21.
