Mexico City, Mexico (CNN) -- A prison warden in the Mexican state of Morelos was abducted as he reported to work Saturday morning and his dismembered body was found later in four locations in the city of Cuernavaca, the government-run Notimex agency reported.

The warden was identified as Luis Navarro Castaneda, director of the Atlacholoaya prison.

Written messages were left with the body remains, Notimex said. The news agency did not report what the messages said.

Navarro's abandoned Toyota truck was found near the prison, Notimex said.

No arrests had been announced as of Sunday morning.
