EAST HARTFORD, Conn. (AP) — A 1-year-old boy died in Connecticut after a dog attacked the child while he was on a trampoline with his mother, police said.

Police responded just after 3 p.m. Wednesday to a home in East Hartford where the child had been bitten several times, Officer Marc Caruso, a police spokesperson, said in a statement.

“Mom and the child were on a trampoline when a larger, mixed breed dog attacked the child,” Caruso told CT Insider. “The mother also sustained minor dog bite injuries and was transported to the hospital.”

Emergency responders performed lifesaving measures and took the child to a hospital, but the boy died “despite the valiant efforts of medical professionals,” Caruso said.

The death is under investigation, Caruso said, adding that two dogs were removed from the home.

“Our thoughts and prayers are with the family and loved ones as they mourn their loss,” Caruso said. “May they find solace and strength during this challenging time.”
