Authorities say a man high on PCP-laced marijuana stabbed two neighborhood children in their home while they slept, killing a 6-year-old boy and critically wounding his 12-year-old sister.

A spokesman for the Camden County prosecutor says 31-year-old Osvaldo Rivera was found hiding between a mattress and a bedroom wall Sunday inside a Camden apartment and was charged Monday with murder and attempted murder.

The prosecutor says police found blood-stained sneakers inside the apartment where Rivera was arrested that matched bloody footprints in the home where Dominick Andujor was stabbed to death. The boy's 12-year-old sister had her throat slit while she slept in the same room. She remained hospitalized Monday. The hospital has declined to discuss her condition.

It wasn't known if Rivera had an attorney.
