Ian O'Reilly was on a morning trail walk in New Hampshire with his wife and three children when a coyote emerged from the woods near the border between the towns of Exeter and Kensington, and snatched his two-year-old son, WFXT reported.
Earlier in the day, there were two reports of a coyote acting aggressively in the area, with many believing each instance to be linked to the same rabid animal.
"I was running behind the dogs to get them in, and just as I was here, literally, the coyote bit me - in the butt", the woman, Pat Lee, 62, told NBC Boston.
"We tried to de-escalate the situation by kicking it and trying to get it away from us and shoo it away".
O'Reilly and his wife tried to pull the boy away, kicking at the animal and shooing it away.
Kensington Police said Exeter Police were called at around 11 a.m. after the same coyote attacked O'Reilly's family.
"The auto was trying to get the coyote to move out of the road, and the coyote started attacking the vehicle", Kensington Police Chief Scott Cain told NBC Boston. The coyote remained aggressive, biting O'Reilly on his arms and chest. "And then, from there, I was able to suffocate it by using my body weight and scissor-locking it until basically expiring".
"Never underestimate the power of survival, I suppose", he said.
"In the middle of the moment, you're not really thinking or. recording a whole lot", he said.
O'Reilly said he manoeuvred himself into a position that allowed him to put one hand on its windpipe and another on its snout to suffocate the animal.
Police first heard about the coyote shortly before 9 a.m.in Hampton Falls, N.H. on Monday, when they received a call that it had charged a vehicle.
While the woman was fighting to keep the coyote out of the house she was bitten.
Law enforcement officials were searching for the coyote when they got word that it had been killed.
Lee was treated at a hospital and given a rabies booster shot, Kensington police said in a news release.
CBS Boston says the coyote will be tested for rabies, but O'Reilly already is receiving shots.
