ROOSEVELT, Utah (AP) — Authorities say two men have been killed at a Halloween party in Roosevelt and officials are calling the killings a double homicide.

The Duchesne County Sheriff’s Office said deputies called to a home near Roosevelt early Friday found the two men dead and learned that some people who had been at the home left before deputies arrived.

The victim’s identities were not made public and the Sheriff’s Office didn’t immediately say how they died or provide information on a possible motive.

A Sheriff’s Office statement said investigators didn’t believe there was an ongoing threat to the public.

The statement says investigators are seeking information from people who were at the party.
