The Monroe County Sheriff's Office and family of a Chili teen are asking for the public's help in solving the 11-year-old homicide.

Brian Sullivan, 19, was last seen on July 8, 2007 at the Burger King drive-thru located at 1300 Chili Ave. His red Pontiac Sunfire was found nearby on Lettington Avenue.

Investigators believe Sullivan was murdered.

“Time generates opportunity for new information to surface in any case,” Sheriff Todd K. Baxter said in a statement. “This is especially true in the case of Brian Sullivan, whose remains have not been located 11 years after his disappearance. If you have information that can help bring closure to Brian’s family, we urge you to come forward.”
