One ranger was fatally shot and another wounded at Oswald West State Park in Oregon on Tuesday, a local newspaper reports.
The Daily Astorian said a suspect is under arrest. According to reports, the suspect had used the victims' vehicle as a getaway car, and was arrested a short time later after a chase on U.S. Highway 26.
The other ranger was taken to a nearby hospital suffering from a facial wound. A hospital spokeswoman said he was in stable condition.
The slain ranger was identified as 50-year-old Danny Blumenthal. The injured ranger, 51-year-old John I. "Jack" Kerwin, was brought to a fire station by a private citizen after the shooting before being taken to the hospital.
"He is stable and alert," said Andrea Larsen, spokeswoman for Columbia Memorial Hospital.
Jean Thompson, spokeswoman for Oregon State Parks, said this may have been the first time a ranger has been killed in the history of the park system.
"People are in shock, as you can imagine," Thompson said. "This is a very close-knit organization. Our deepest sympathies go out to everyone's families and to the larger parks family as a whole."
Rangers do not carry guns - they are responsible for general maintenance, collecting fees and issuing citations, Thompson said.
She had no information on a possible motive for the shootings.
Oswald West State Park is along U.S. Highway 101, 65 miles west of Portland. The park, popular with surfers, has overnight camping and huts on the beach with scenic overlooks of the water.
