A man who admitted killing his landlord in 2006 and hiding the body in a Long Island cesspool has been sentenced to 21 years in prison.

Jaime Rosario had pleaded guilty to first-degree manslaughter in June.

Nicolo Caietta of Mastic Beach had been missing for nearly two years before police found his remains.

Police said Rosario admitted hitting his landlord’s head with a baseball bat, putting his body in a closet overnight, and then hiding it in the backyard cesspool.

His attorney, Jason Bassett, described Rosario as cooperative.
