The man who killed his two young sons and ex-wife in south Minneapolis on Sunday had a permit to purchase a firearm and left a suicide note at the scene.
Hennepin County court records reveal new details about the triple-murder and suicide that's shaken the community. Documents were filed on the same day that the medical examiner officially released the identities of family members and their causes of death.
A search warrant unsealed Tuesday indicates a suicide note was found but did not reveal what it said.
David Schladetzky, 53, is suspected of fatally shooting 39-year-old Kjersten Schladetzky, their 8- and 11-year-old sons and himself at the home in the 2700 block of Oakland Avenue, where the couple raised the boys together until they divorced in June.
Schladetzky arrived to pick up the kids as he did most Sundays, but this time he had a gun. As the boys ran away, he followed them into the snow-covered front yard and fired, again and again.
Then he stormed inside and shot his ex-wife several times before stabbing her in the chest, an autopsy revealed. He later turned the pistol on himself.
Minneapolis police officers and SWAT teams converged on the blue and white two-story home around 10 a.m., sending the neighborhood near the American Swedish Institute into a virtual lockdown.
In what Police Chief Medaria Arradondo called an act of heroism, officers ran into the open and scooped the brothers up, not knowing if they were dead or injured.
