On February 9, 2021, a mass shooting and bombing occurred at a medical clinic in Buffalo, Minnesota, United States. Just before 11:00 a.m. CST, Gregory Paul Ulrich, a 67-year-old man, shot five people at Allina Health's Buffalo Crossroads facility. One victim, Lindsay Overbay, died, and three others were critically injured from gunshot wounds. All of the victims were medical clinic staff. During the attack, Ulrich discharged three improvised explosive devices, one of which failed to detonate. He surrendered to police who were dispatched to the clinic, and he was taken into custody. He admitted to authorities that he fired on people inside the clinic and set off bombs.Ulrich faced several charges before the Wright County District Court: first-degree premeditated murder, four counts of first-degree attempted premeditated murder, and discharge of an explosive or incendiary device. Police investigators and prosecutors believed Ulrich's motive for the attack was in retaliation for his dissatisfaction with treatment at the clinic, and at the doctors that had stopped prescribing opioid painkiller medication for him. Several warning signs about Ulrich's past behavior and possible motives were not sufficient to prevent the attack from being carried out. Controversially, the Buffalo police department issued Ulrich a permit for the gun he used to carry out the shooting, despite Ulrich having a restraining order against him for past threats at the clinic and his previous criminal offenses.At his trial in 2022, Ulrich admitted that he purchased the gun, assembled pipe bombs, and carried out the attack as retaliation against clinic staff. A jury convicted him on all charges and a judge sentenced him to life in prison without the possibility of parole.
