GEORGETOWN, Mass. (AP) – Authorities say an 8-year-old Massachusetts boy helping his father with the family’s cows was trampled to death when one of them got spooked.

The Essex District Attorney’s Office says Peter Carter and his little son George and son were exercising some of the family’s 20 cows at their home in Georgetown when one apparently became startled and trampled the child. It happened around 12:45 p.m. Saturday.

The boy was taken to a hospital, where he was pronounced dead.

Massachusetts State Police are investigating the death.

Peter Carter said he doesn’t know what may have spooked the pregnant female cow. He doesn’t even remember how he broke his leg in the incident.

Georgetown is located in northeastern Massachusetts, about 30 miles from Boston.
