On May 10, 2011, Sgt Brian Dulle was struck and killed by a suspect's vehicle while deploying stop-sticks at the intersection of US 42 and Utica Road in Mason, OH.  After striking the officer, the suspect fled the scene on foot but was later arrested.  Sgt Dulle's killer was convicted of murder and several other charges in October 2011 and was sentenced to 25 years in prison.  Speeds in the chase through Franklin, Springboro and Waynesville exceeded 100 mph and there were skid marks at the crash site that stretched for 65 feet. 

This site is not to mourn his death but to honor his memory by promoting the charity events held in his memory.
