Officials say that the 4-year-old boy who fell from a second story window at a home in Waconia on Sunday suffered critical injuries. Carver County sheriff’s deputies say a neighbor noticed the boy had fallen about 15 feet to a patio below, notified the child’s parents and called 911 Sunday afternoon. The boy was rushed to Ridgeview Medical Center and later transferred to Hennepin County Medical Center. Authorities say he’s in critical condition with a head injury. Investigators have determined that the fall was an accident. Sheriff Jim Olson says windows open just five inches can create a hazard for young children, and that window screens offer little protection to keep kids inside. Olson urges parents to consider installing window safeguards.
