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.
