RICHMOND TOWNSHIP, Pa. — Two firefighters traveling in a utility vehicle along a Pennsylvania road during a search for a missing woman were killed in a head-on crash with a car, officials said.

The two members of the Walnuttown Fire Company died after the crash with a Toyota Camry at about 6 p.m. Saturday, roughly 45 miles (72 kilometers) northwest of Philadelphia. Fire Chief Jeff Buck and Assistant Fire Chief Robert Shick Jr. were heading north when they were struck by a sedan heading south on Route 222, according to the Berks County Coroner.

NBC Philadelphia reported that the utility vehicle was riding on the shoulder of Route 222 when the Camry swerved off of the road. Police told the station that a male and a female who were in the Camry when it crashed fled and were later arrested.

Video from the crash scene shows the utility vehicle on its side.

No further details about the arrest or the search for the missing woman were immediately available Sunday.

A call and an email seeking information were made to the Fleetwood Police Department.

Autopsies on the firefighters, both residents of Fleetwood, were scheduled for Monday.

“At this time we would like to send our thoughts and prayers” to the Shick and Buck families, the Walnuttown Fire Company said in a Facebook post. “Rest easy chiefs, we got it from here.”

A toddler was lightly injured by a wolf at a Pennsylvania theme park zoo after he crawled under a fence and stuck his hand into the animal’s enclosure, officials at the zoo confirmed Sunday.

The child was never inside the wolf habitat at the ZooAmerica North American Wildlife Park, which is part of the Hersheypark theme park, and the officials characterized the injuries as minor without elaborating.

After the “unsupervised” child reached the metal enclosure around the wolf habitat on Saturday morning and put his hand through, a wolf approached “and made contact with the child’s hand,” according to a statement from the zoo.

“This type of response is consistent with natural animal behavior, and was not a sign of aggression,” the zoo said in a statement. “Our habitats are designed with multiple layers of protection, and clear signage and barriers are in place to help ensure safe viewing. Guests are expected to remain within designated areas and closely supervise children at all times.”

The zoo is part of the entertainment complex in Hershey, Pennsylvania, featuring a chocolate-themed amusement park. The zoo’s website says it has three gray wolves.

Hersheypark made headlines last summer when a lost boy wandering a monorail line above a crowd was rescued by a park visitor who climbed onto a building and jumped onto the rails. The child was unharmed and reunited with his family.
