DENVER -- The Jefferson County Sheriff's Department asked residents Tuesday morning to help identify a suspect who is intentionally starting fires along Highway 285.

On Tuesday morning at about 10 a.m., there were two spot fires set within minutes of each other along Highway 285, between Bailey and Morrison, officials said.

One fire was just north of Turkey Creek Road and another was located at Surrey Ridge Road, near the Homestead subdivision, 7NEWS reported.

"They were relatively close together ... within several blocks of each other," Jefferson County Sheriff's spokesman Jim Shires told 7NEWS.

The spot fires were quickly extinguished and did not hurt any residents or damage any property, Shires said.

But, as evidenced in the Hayman Fire, one small spot fire could quickly blow up and become an uncontrollable wildfire that can threaten thousands of homes.

Investigators are in the area and are asking the public to be on the lookout for a suspicious vehicle or a suspicious person.

If you have any information that could be helpful to investigators, you are asked to contact the Jefferson County Sheriff's Department.
