3 injured in Memorial Day parade mishap in Elm Grove

Three people were injured when show ponies pulling a wagon in the Memorial Day parade in Elm Grove ran up onto a crowded sidewalk.

Authorities say a 9-year-old Racine boy and a 58-year-old Brookfield woman who were struck by the carriage were taken to a hospital. The boy suffered a minor cut and stomach pain. The woman suffered ankle, shoulder and head injuries.

A 77-year-old Milwaukee man was struck by the ponies but refused transport to a hospital.

Police say the ponies might have been startled by fireworks or by tennis balls thrown by children.
