MINNEAPOLIS (WCCO) — The Hennepin County Medical Examiner has released reports on the deaths of two adults and their children in South Minneapolis over the weekend, confirming the incident as a murder-suicide.

The horrific scene played out around 10 a.m. Sunday at the home on the 2700 block of Oakland Avenue South. Neighbors witnessed two boys as they were shot out on the yard by their 53-year-old father, David Schladetzky.
