A fugitive considered armed and dangerous was still on the loose Tuesday night.
Authorities said Tuesday that they don't know if Douglas Linn Snowden is still in the area after an unsuccessful manhunt Monday near Kansas Highway 10 and the Douglas-Johnson county line.
U.S. Marshals said Snowden is wanted by federal authorities for a parole violation and by Johnson County Sheriff's officers for aggravated assault and intimidating a witness.
The search, which employed dogs from the Kansas Department of Corrections and helicopters from Kansas Highway Patrol, began shortly after 8 a.m. Monday. They stopped about 10 p.m. Monday.
Tuesday, authorities downgraded their efforts, and only patrols by Douglas County Sheriff's officers were conducted.
"Patrols in that area have been heightened," Sheriff Rick Trapp said. "That area of the county is under close scrutiny."
The drama began Monday when a Douglas County deputy attempted to stop a car east of Eudora thought to be driven by Snowden.
The driver refused to stop and led the officer on a chase that ended when the car ran off the road near North 1400 Road and East 2400 Road, the sheriff's department said. The suspect fled on foot.
"That's a heavily wooded area," Trapp said. "He could be 10 feet away and we might not see him."
Sheriff's officers weren't specific about the area searched, saying that it was in northeast Douglas County and near Kansas Highway 10.
Snowden had lived in the DeSoto and Eudora areas, said Deputy Marshal Matthew Cahill of the U.S. Marshal's Office in Kansas City, Kan.
Comments Snowden had made in the past led officers to consider him armed, marshals said. But Trapp said no weapon was seen during Monday's chase.
Snowden, 48, a white male is 5-feet-8 and weighs 150 pounds. He has blue eyes and gray/white hair and he wears glasses.
A scar is visible on his nose and there are tattoos on both arms.
He was last seen wearing a pink and red plaid or striped shirt along with light colored pants and a black hat.
Anyone seeing Snowden is asked to call the nearest law enforcement agency.
