Man charged with killing cop, worker in Waltham crash has long criminal record

An unlicensed New Hampshire pickup truck driver is accused of crashing into a police officer and a utility employee at a work site in Waltham, killing both, then pulling a knife on another officer before stealing his cruiser and crashing, law enforcement officials said.

Peter Simon, 54, of Woodsville, New Hampshire, appeared in court Thursday and was arraigned on multiple charges, including two counts of manslaughter, armed robbery, assault, and leaving the scene of an accident. A lawyer entered not guilty pleas on his behalf and a hearing date was scheduled for Dec. 14.

New Hampshire court records show Simon in 2017 pleaded guilty to charges of driving under the influence, second degree assault and disobeying an officer and served time in prison. He also has multiple additional criminal cases dating back to 2009, the records show.

There is no record of a lawyer for Simon after the arraignment. No one answered the phone at a publicly listed phone number for his residence Thursday.

Two other utility workers were injured in the initial crash Wednesday afternoon in Waltham and “multiple other vehicles” were struck by the truck before it was abandoned, Middlesex District Attorney Marian Ryan said in a news release. The two other workers were treated and released from the hospital.

“Clearly what happened ... is an unimaginable tragedy,” Ryan said at a news conference. “These two men were doing their job at 4 o’clock in the afternoon when they were killed and crashes like this happen far too often.”

After the cruiser crashed, police said they arrested the driver after a brief foot pursuit.

The events unfolded after Simon suddenly attempted to make a U-turn, striking a vehicle, prosecutors said. The truck continued for about a quarter mile before Waltham police Officer Paul Tracey, 58, and a 36-year-old National Grid worker identified as Roderick Jackson, of Cambridge, were struck. Tracey was working a police detail at a utility work site, a trench that was marked by orange cones and signs and yellow flashing lights, prosecutors said in court. The truck also struck a National Grid truck.

The truck kept going and struck other vehicles before Simon got out and fled, encountering another Waltham officer who was responding to the crash. Simon turned on the officer, brandishing a knife, before taking his cruiser and driving off, prosecutors said.

Other officers pursued Simon and tried to stop him, but each time, he would veer his car into an oncoming officer, prosecutors said. He ultimately crashed and was arrested following a brief foot chase.

Tracey and the utility worker were taken to a hospital, where they died from their injuries, prosecutors said.

Tracey was a 28-year veteran of the Waltham Police Department.

Dozens of police officers, emergency medical workers and firefighters — blue and white emergency lights flashing — lined the streets near the medical examiner’s office in Boston in a show of solidarity as Tracey's body was transported to the facility.

Jim Tracey told reporters his brother will be sorely missed by his family and friends.

“We just want to thank the Waltham community for the tremendous outpouring for our brother Paul. He was a tremendous husband, father, uncle, and brother, and loved by everybody in the community,” Tracey said. “Anybody who knew him, his laughter, his compassion. It will be missed.”

On Thursday, Gov. Maura Healey ordered that flags be lowered to half-staff at all state buildings in Tracey's honor.

Jackson’s brother Manuel Asprilla-Hassan told reporters he was devastated. He said he spoke to his brother shortly before the crash and they had talked about plans to attend the Rose Bowl Game.

“He meant everything to me. He meant everything to everybody. The city of Cambridge knows who he is. When everybody forgets about him, we will remember,” Asprilla-Hassan said. “This is a nightmare that I’m living in.”

“He was a compassionate police officer, and always looked out for the underdog,” Chief Kevin O'Connell said at the news conference. He was an amazing husband, a loving father, and a friend to all.”
