Milwaukee police have arrested three people involved in a Wednesday night shooting which injured a 3 year old child. Officers recovered about 40 shell casings after shots were fired into the back of a house. The girl was hospitalized and is expected to recover. Her father says his wife was putting their kids to bed at about 10:20 P-M when at least four shots hit their home. He says they are lucky they weren’t outside watching fireworks when the bullets started flying. The girl’s name hasn’t been released.
