DENVER -- Boulder police are offering a reward of $1,000 for information that leads to the safe return of a bus driver who went missing earlier this month.

Police said James "Jim" McPhee went missing on Oct. 5. He left his mother-in-law's home at about 4 p.m. and hasn't been seen since.

McPhee said he was going to drop off some DVDs at a library. Investigators said they learned McPhee did drop off the DVD's but they have no further clues about his disappearance.

"His family reports that he did not have any plans to travel, and they are very concerned about his welfare," said police spokeswoman Sarah Huntley.

"At this point, no suspicious circumstances have been found," Huntley added.

McPhee is described as a white man, about 160 pounds and 5 feet, 8 inches tall, with green eyes and short, brown hair. He has a beard and goatee that is a reddish color. He speaks with an English accent.
