CAMDEN, N.J. (CBSNewYork/AP) – A man has been arrested for murder in connection to the stabbings of two young children in New Jersey early Sunday.

Camden authorities said a 31-year-old man has been charged with murder and attempted murder in the stabbings of two sleeping children.

Jason Laughlin, a spokesman for the Camden County prosecutor’s office, says 31-year-old Osvaldo Rivera, of Camden, was arrested Sunday afternoon.

Rivera is in jail awaiting arraignment.

Six-year-old Dominick Andujor was stabbed to death early Sunday inside his home in Camden.

Authorities say his 12-year-old sister also was critically wounded, her throat slit, as she slept in another room.

She is hospitalized at Cooper University Hospital in Camden. The hospital won’t discuss her condition, citing privacy concerns.

The girl, whose name has not been released, went door to door in her Camden neighborhood to get help and finally reached the home of Nakyta McCray, who called 911.

She said the girl “was barely breathing” and bleeding profusely when emergency personnel arrived.

It wasn’t clear yet why the children were targeted.

Authorities say the children were being watched by a 14-year-old girl when the attack happened around 2 a.m. Sunday. She was unharmed.

Camden, across the Delaware River from Philadelphia, continually ranks as one of the nation’s most dangerous.

The double stabbing comes shortly after another child died a violent death in Camden. On Aug. 22, a 33-year-old city woman allegedly decapitated her 2-year-old toddler and then fatally stabbed herself.
