Authorities in eastern Iowa have identified the victim and the underage driver involved in a fatal Saturday crash. The Highway Patrol says 13-year-old Mitchell Slocum of West Branch was driving the S-U-V that went out of control on a gravel road near Iowa City and rolled into the ditch. A 16-year-old passenger, Madison Brigham of Iowa City, was killed. The driver, Slocum, was injured and taken to University Hospitals but his condition isn’t being released. Troopers say the S-U-V, a Chevy Tahoe, belonged to the dead boy’s mother but it’s unclear why the other boy, the 13-year-old, was driving it.
