Officers in Dickson, Tennessee, said there are motels there that have had the same people living in them for years.

Police said the city's two live-in motels are keeping them very busy and they have responded to almost 250 emergency calls between them in the past year.

911 calls have included reports of assault, meth labs and recently even murder.
