Authorities say they have charged a man with fatally stabbing a 17-year-old girl in an upstate New York neighborhood.

The Wayne County Sheriff's Office says 19-year-old David Knight-Hollis was charged Friday with second-degree murder in the death of Alyssa Taft, a senior at Sodus High School.

Authorities say the two had previously dated, but weren't in a relationship when Taft was killed.

Court documents say Knight-Hollis stabbed the teen in the chest and slit her throat Thursday afternoon at his home in a mobile home neighborhood in Sodus (SOH'-duhs), 25 miles (40 kilometers) east of Rochester.

Officials say her body was found at his home.

Knight-Hollis pleaded not guilty and was being held without bail in the county jail. Authorities said he doesn't have a lawyer yet.
