SALT LAKE CITY (AP) — Friends and family were set to gather Friday afternoon in a small Utah town for a funeral to remember a mother and three of her children who police say were killed by her teenage son. Prosecutors say 16-year-old Colin “CJ” Haynie “methodically” killed his mother and siblings one by one as they returned home over a period of five hours on Jan. 17. Prosecutors have said the teenager shot his father in the leg before the older man wrestled a handgun away. The boy from the small town of Grantsville west of Salt Lake City has been charged with 10 felonies.
