MADISON, Wis. -

A K-9 helped officers find drugs police said an Illinois man who ran from a traffic stop dropped as he fled.

Madison police said early Friday morning, an officer responded to a report of a man asleep behind the wheel stopped in the eastbound offramp from the Beltline Highway to Stoughton Road.

At about 4:46 a.m., police said they found Dedonta Davis, 24, sleeping in his running car with the music on and his foot on the brake. Police said a concerned citizen had stopped behind the car and activated his hazard lights to warn others of the situation before calling police.

According to the report, the officer knocked loudly on the driver's side window, but could not wake the sleeping man. He then used his flashlight to illuminate Davis' face, and he eventually woke up, the report said.

Police said the Evergreen Park, Ill., man told the officer he had not been drinking or using drugs and got out of the car. According to the report, it appeared Davis was reaching for his wallet when suddenly he bolted. Police said he ran north on Stoughton Road, under a bridge, and then up the onramp to westbound lanes of the Beltline Highway.

A Sun Prairie police dog arrived to assist with the search and led police to eight small bags of marijuana, the report noted. The track indicated Davis had escaped into a marshy area.

About 1.5 hours later, the MPD received information that McFarland police were responding to a suspicious man call. The person in question was wet and muddy and had just appeared at a Terminal Drive gas station on foot.

When the MPD officer showed up, he could see two McFarland officers inside the service station talking with a man.

Police said the MPD officer immediately identified him as Davis. According to the report, when the man saw the MPD officer walk in, he said, "Oh (expletive)."

Madison police arrested Davis on suspicion of possessing THC with intent to deliver and resisting arrest.
