Authorities in Lincoln County are asking for the public's help as they continue to investigate the death of an Idaho man whose body was found last week.

A rancher found the body of 30-year-old Jacob Ivan Rasmussen on Friday, Dec. 2, and called the Lincoln County Sheriff's Office around 1:30 p.m.

Rasmussen's body was found in what was supposed to be an unoccupied ranch building about 25 miles north of Kemmerer.

Now, the Sheriff's Office is asking for the public's help in finding Rasmussen's vehicle -- a black 2010 Toyota 4Runner with Idaho license plates 1BZ7355.

Anyone who knows where Rasmussen had been in the days before his death, or anyone who has seen his SUV, is asked to call the Lincoln County Sheriff's Office at 307-877-3971 or 307-885-5231.
