Buffalo shooting: Minnesota gunman identified as Gregory Paul Ulrich

The shooter who opened fire inside a Minnesota health clinic Tuesday was “no stranger” to law enforcement — and had been disgruntled with the healthcare system, police said.

Gregory Paul Ulrich, 67, has been identified as the gunman who killed at least one person and critically injured four others around 11 a.m. at the Allina Health Clinic in Buffalo, police and reports said.

“We are very familiar with the suspect,” Buffalo Police Chief Pat Budke told reporters.

Budke said that it was likely a targeted attack against the facility or someone inside — noting that Ulrich had previous conflicts with health care clinics in the area.

“All I can say is, it’s a history that spans several years and there’s certainly a history of him being unhappy with health care and with the health care that he’d received,” Budke said.

But despite his known gripes, there was “nothing to indicate that we would’ve been in the situation where we are at today,” Budke said.

Authorities responded to the clinic Tuesday to find a “horrible” scene with several people injured — as well as a potential explosive device that forced them to evacuate the premises. 

“Upon arrival, we also located several victims, it’s a horrible looking scene and our staff immediately began rendering aid to those victims,” Wright County Sheriff Sean Derringer said. 

Officers also later found multiple suspicious devices at a nearby Super 8 motel where Ulrich was staying, authorities said. It’s unclear whether they detonated.

Ulrich was taken into custody shortly after the shooting.

Deringer said that Ulrich had been known by the agency for nearly two decades.

“We have had several calls for service regarding Mr. Ulrich dating back to 2003,” he said, adding that he was “no stranger to law enforcement.”

His previous brushes with the law include arrests for drunken driving and possession of small amounts of marijuana between 2004 and 2014 —  including two convictions for gross misdemeanor drunken driving that resulted in jail time.
