An Ottumwa man will stand trial this summer for two different shootings. 19-year-old Jacob Heckethorn is accused of first degree murder and attempted murder for a shooting last August that left William Shettlesworth dead and Clifford Collett, Senior injured. Heckethorn’s trial for killing Shettlesworth starts June 25th; then his trial for shooting Collett starts in late August. Court records show Heckethorn will claim self-defense in both cases.
