UPDATE: Police allege a 60-year-old Davenport man committed first-degree arson early Saturday when he used a lighter to set a mattress on fire in at the Comfort Inn, according to arrest affidavits.

Davenport Fire Investigators determined that the fire was intentionally set, according to a news release. Fire Investigators and Davenport Police arrested Terry Lee Kirby, who faces charges of first degree arson and first-degree criminal mischief.

Kirby “intentionally set the fire knowing the hotel was occupied,” affidavits say. “The defendant admitted using the lighter to ignite papers and placed them on the bed causing the bed sheets and mattress to start on fire,” police allege in affidavits.

The fire, affidavits show, caused the sprinkler system to activate, “sending copious amounts of water onto the 3rd floor and floors below. The cost of replacing, restoring and repairing of which is in excess of $10,000.”

The incident

About 6:50 a.m. Saturday, firefighters responded to a fire at the Comfort Inn, 8300 Northwest Blvd. Six fire apparatus, one Incident Command vehicle, and two support vehicles went to the scene, with 21 personnel.

Crews saw no fire on the exterior. As they entered the third-floor hallway, they found moderate smoke. Firefighters entered Room 311 and found a small fire on the bed. The fire had been extinguished by the sprinkler system, the release says.

Crews ventilated the room and removed the smoke from the building, which sustained substantial damage by fire, smoke and water. Damage left numerous rooms unusable.

Medic Ambulance transported one occupant to Genesis Medical Center – East Campus for minor injuries.

The fire remained under investigation Saturday night. Any additional information will be released by the fire marshal, the release says.

Kirby , who is being held on $25,000 cash-only bond in Scott County Jail, is set for a preliminary hearing Feb. 22 in Scott County Court.
