WALTHAM — A New Hampshire man is expected in Waltham District Court on Thursday to face charges in connection with the deaths of a police officer and a utility worker.
Peter Simon, 54, of Woodsville, New Hampshire, is accused of manslaughter and armed robbery after an incident Wednesday afternoon that claimed the lives of a Waltham police officer and a National Grid worker.
Authorities say Simon was driving on Totten Pond Road around 4 p.m. when he crashed his truck into Paul Tracey, 58, a Waltham police officer working a detail, and a 36-year-old National Grid employee from Cambridge, whose name has not been released.
Both were killed in the collision.
Following the crash, Simon allegedly struck two other National Grid workers with his vehicle, inflicted injuries, and hit several cars.
According to the Middlesex County District Attorney’s Office, Simon then threatened another officer with a knife and commandeered his police cruiser while attempting to escape.
He was apprehended after a brief pursuit on foot.
Simon faces two counts of manslaughter and one count of armed robbery.
Officials indicated that additional charges are likely as the investigation continues.
