Jacob Geiser, 23, shot and killed Ethan Honer, 20, after Honer showed up at Geiser's home with his new 21-year-old girlfriend. He then shot himself. Geiser was the ex-boyfriend of the woman Honer was dating.

[jump] It was an "ex-girlfriend situation," Sheriff Brian Schlueter told the Star Tribune.

"The woman came to pick up her dog and brought along the new boyfriend," he continued. "[Geiser] wasn't supposed to be home."

After Honer's girlfriend called police to report the shootings, Geiser was transported to a hospital in St. Cloud and placed on life support, but he died from his injuries the next day. Honer was pronounced dead at Geiser's house.
