? Greenwich homeowners spent another Saturday sweeping up piles of glass and cleaning egg off their cars after vandals struck again.

Police say more than 30 vehicles were damaged overnight. Some neighbors reported hearing strange sounds. Vandalism victim Bob Hallock is upset about the costly repairs and questions why the suspects cannot find a better use of their time. Homeowners believe teenagers are behind the crimes, which also happened in March.

Investigators do not have any suspects at this time, but say several cars were also damaged in nearby Port Chester, New York.
