GLENWOOD, Iowa (AP) — An Ohio man is on trial for fatally shooting an 18-year-old woman in western Iowa. Prosecutors charged 27-year-old Mark Troutman, of Sylvania, Ohio, with first-degree murder in the slaying of Kathryn Weber. She was found bleeding outside her Glenwood workplace on Sept. 17 and soon died at the scene.

Troutman was arrested at a Glenwood motel that night. Authorities described Troutman as Weber’s former boyfriend. The Daily Nonpareil reports defense attorney Eric Nelson said Tuesday that Troutman intended to commit suicide in front of Weber, and hadn’t planned to harm her.

Prosecutors say they believe Troutman planned to shoot Weber because he was distraught over their breakup.
