Authorities say a man considered a "person of interest" in a Missouri fire that killed four people was arrested after he was found walking naked in a northwestern Arizona town along Interstate 40.

The Yavapai (YAV'-uh-py) County Sheriff's Office says the 24-year-old man was arrested Sunday and is jailed on suspicion of theft and of displaying a fictitious license plate.

Sheriff's spokesman Dwight D'Evelyn says the man's wallet was found in clothing lying next to a car at a Seligman motel whose manager called authorities to report a suspicious vehicle.

D'Evelyn says the car was reported stolen in Missouri and that it had a license plate also reported as stolen.

Missouri authorities want the man for questioning about the deaths of three adults and an infant in a fire Friday night at a rural home near Edgerton in Platte County.

The Kansas City Metro Squad had announced Sunday that the man was found unharmed but didn't say where. The man was sought for questioning about the deaths of three adults and an infant in a fire that was reported just before midnight Friday at a rural home south of Edgerton in Platte County.

Authorities are investigating the deaths as possible homicides. The names of the victims have not been released.
