NEWARK — Authorities say a New Jersey man killed a woman after an argument and that her head has not been found after he dismembered her remains to try to get rid of her body.

Prosecutors said Friday that 57-year-old James Edwards, of Newark, was charged this week with the November murder of 50-year-old Pamela Davis.

Chief Assistant Prosecutor Thomas Fennelly says Edwards allegedly got into a dispute with Davis before killing her.

Her decapitated remains were found in Newark in November more than a week after her family reported her missing.

Edwards was charged with desecration of human remains in November and the charges were upgraded this week based on a medical examiner's findings.

He was being held on $500,000 bail. A message left with the public defender's office wasn't immediately returned.
