Wright County Sheriff Sean Deringer said he often gets emotional when he relives Feb. 9, the day when a man entered the Allina Health Clinic in Buffalo and opened fire.
The attack killed 37-year-old medical assistant Lindsay Overbay and seriously injured four others.
But the days since have been full of hope and acts that prove the power of community, he said at a prayer service Sunday night at Buffalo Evangelical Free Church.
Residents have bought meals for the investigators and sent over coffee and doughnuts. The Sheriff's Office has received dozens of thank-you cards and even one birthday card, which was postmarked from California.
In shaky penmanship, its message read: "I wanted you to know that I am praying for you and lifting your staff up in prayer."
On Sunday, participants prayed for victims of the shooting and their families, as well as the law enforcement officers, first responders and the clinic's patients and staff. They also prayed for the suspect, Gregory Ulrich. According to search warrants, Ulrich was angry at the clinic's doctors for cutting off his opioid prescription.
Authorities believe Ulrich's dependence on pain medication was a "driving force" behind his assault on the clinic.
Sunday's service, which drew about 50 people, featured prayers from faith leaders from seven area congregations as well as chaplains, and Buffalo Mayor Teri Lachermeier, Pat Budke, the city's police chief, and Deringer.
