BURLINGTON TOWNSHIP - The family of a missing Florence Township teen is offering a $10,000 reward for information leading to her return.

Sarah Townsend's parents say the 18-year-old left Monday morning for school at Allentown High School and never returned home. Police say her car was found at Green Acres Park in Burlington Township next to a pond. Investigators say the engine was running, the door was open and Townsend's purse and cell phone were inside.

Police suspended their search Tuesday after they say they were "given good reason that Townsend was considering harming herself," according to the Courier Post.

Friends and family members scoured the park searching for the teen on Wednesday. Students at Allentown High School plan on holding a vigil for Townsend today.
