Chicago police are searching for an SUV possibly used by a gunman who shot a 5-year-old boy in the head with a stray bullet Monday evening as he was playing with an iPad inside a home. The child was on a couch around 7:30 p.m. when an SUV drove by the home on the 200 block of West 115th Street and someone inside opened fire, police said. The child was shot in the head and rushed to the hospital to undergo surgery.
