A Centereach man pleaded guilty Friday to killing a teenager and then burying his remains in his neighbor's yard.

John Mann IV, 20, admitted to beating the homeless Hempstead teen to death in 2019.

He lured 16-year-old Henry Hernandez to a hidden place, duct taped him and then fatally struck him.

The defendant later dug up the skeletal remains and put them in his neighbor's yard nearly a year later.

Mann is expected to be sentenced to 20 years in prison.
