Investigators say a bear that killed a Rutgers University student was unprovoked and was behaving in “a predatory manner” ahead of the attack.

Darsh Patel, 22, was hiking with friends last month in the Apshawa Preserve in West Milford when they spotted a black bear following them. They ran away, splitting up in the process. Patel's friends called police when they realized he was missing.

Darsh Patel's Sept. 21 death, the first known fatal attack by a bear against a human being in New Jersey, was attributed to a "mauling" on the death certificate, according to the statement. The animal that attacked him was labeled a "predatory bear."

"The behavior of the bear before the attack was typical of bears involved in predatory attacks on humans," West Milford Police Chief Timothy Storbeck and state Department of Environmental Protection spokesman Larry Ragonese said in the statement.

It was unclear on Thursday whether the state ever before reported a bear acting in such a manner toward a human. Bears have attacked and killed livestock and pets but have not been recorded as having killed a human in the state. Ragonese said he does not recall a predatory attack on a human in the state but added that the DEP has received reports of aggressive behavior by bears, including bluff charges.
