York County Sheriff William King confirmed that David Goodwin, 41, was the Lebanon town employee who died last weekend after being injured while working as a roadside flagger.

Goodwin, who lived in Lebanon, was directing traffic on Shapleigh Road on June 15 when an excavator bumped into him, knocked him to the ground and broke his pelvis and legs, according to King. First responders brought him to Portsmouth Regional Hospital in New Hampshire where he died on June 24.

Goodwin’s mother, Barbara Richardson, told the Press Herald Friday that her son had been “run over.”

“My son died from the results of someone’s careless action,” she said.

On Thursday, the town of Lebanon released a statement confirming a town employee had died, but officials refused to confirm the worker’s identity or discuss the accident. That release mistakenly said the employee had died on June 25.

The York County Sheriff’s Office is coordinating an investigation with the Occupational Safety and Health Administration, which is responsible for investigating workplace deaths, King said.

The town has said the Maine Department of Labor is also investigating the incident.

Richardson said Goodwin died only weeks before he was to be married and left behind five children.

“My son loved life and his children and the love … whom he was going to marry this July 4,” Richardson wrote. “Instead we are burying him. I don’t know what happened to my son, and I am not going to stop until I find out.”
