A man was killed during the strong storm in Massachusetts on Monday, as a tree collapsed on his trailer amid high wind gusts and heavy rain.

The powerful storm has been toppling trees and power lines, sparking power outages across the state and especially the South Shore in Plymouth County — where police responded to this fatal incident.

Hanover Police at around 9:47 a.m. received a 911 call that a large tree had fallen outside of the workplace at 99 Industrial Way.

The tree had collapsed on a small travel trailer and a man was trapped inside, the caller told police.

Hanover first responders were able to free the man from the trailer. He had suffered severe head trauma and was transported to South Shore Hospital, where he was pronounced dead.

The victim has been identified as 89-year-old Hingham man Robert Horky.

Massachusetts State Police assigned to the Plymouth County District Attorney’s Office are investigating.

More than 270,000 power outages were reported across the Bay State Monday afternoon, according to the Massachusetts Emergency Management Agency tracker. About 50% of Hanover was in the dark.

The majority of the outages were on the South Shore and along the coast. Nearly 100% of Scituate was without power as of 3 p.m. Monday.

“We know the timing of this storm is terrible as people are trying to enjoy time off or prepare for the Christmas holiday,” said Eversource President of Regional Electric Operations Craig Hallstrom. “The fierce winds and heavy rains brought down trees and limbs that caused significant damage to the electric system and widespread power outages in most of Eastern Massachusetts, as well as communities in Western Massachusetts.

“We have hundreds of crews on the ground working but with outages being so widespread it will take some time, especially as we continue to take on damage and outages throughout the day, even after the storm passes because of the weakened state of trees and the saturated ground,” Hallstrom added. “We are bringing additional contract crews on to support our restoration effort, and our employees are committed to working around-the-clock until all of our customers affected by this storm have their power back.”
