A search is underway for a 17-year-old girl who went missing in suburban Aurora. Police say Ava Michelini was last seen Saturday on the far east side of the city after being dropped off at a friend’s house. She left the friend’s house and isn’t responding to phone calls or text messages. The teen was last believed to be in Elburn, Illinois but likely has left that area. Anyone with information is asked to contact Aurora police.
