PLAINVIEW - A sex offender has been convicted of carjacking a teenage girl from Plainview.

Cops say 51-year-old William Tockash carjacked the teen while she was stopped at a red light in front of the Plainview-Old Bethpage Library in 2009.

Investigators say Tockash then forced the 17-year-old girl to drive through a neighborhood before she was able to escape. Tockash faces up to 14 years in prison when he is sentenced in April.
