CROWN HEIGHTS - The family of a Brooklyn teenager is holding a search party after he went missing a day before his high school graduation. Police say 15-year-old Ariel Pitter went missing last Sunday on his way back from his grandmother's house. His family says he was abducted and that it called police when they noticed it took him too long to get home. Family members are handing out flyers and talking to neighbors for information. A makeshift vigil has been put in place near his apartment, where his sneakers and school uniform hang in remembrance. Anyone with information is urged to call Crime Stoppers at 1-800-577-TIPS.
