A tragic end to the search for a 5-year-old boy in Illinois: Investigators believe they have found the body of Andrew "AJ" Freund wrapped in plastic and buried in a shallow grave, and his parents have been charged with first-degree murder. The remains were found in a rural area a few miles from the boy's home, the AP reports. Freund's parents, Andrew Freund Sr. and JoAnn Cunningham, reported him missing last week, but later stopped cooperating with police. Crystal Lake police Chief James Black said at a news conference Wednesday that investigators were led to the body after interviewing AJ's parents overnight and presenting cellphone evidence to them. Police are confirming the body is AJ's. (Girl, 11, found dead after painstaking all-night search.)
