A man was charged with killing a fellow patient at a group home for special needs adults in West Hempstead.

Police say 35-year-old Derrick Smith stabbed 48-year-old Charles Psoinas several times with a folding knife Sunday at the Garden Place Community Residence. Psoinas later died at Winthrop University Hospital.

The group home is run by Pilgrim State. Some residents say the facility has had many internal problems in the past.
