A Tuesday shooting at a Buffalo, Minnesota medical clinic resulted in five people injured and the shooter in custody, along with a bomb squad at the scene looking at a “suspicious package.”

Buffalo Police, Wright County sheriff’s deputies and area SWAT teams were dispatched to the Allina Health Care Clinic at 755 Crossroads Campus Drive around 11 a.m. on reports of a shooting, according to KARE 11. The city is located about 40 miles northwest of Minneapolis.

At a 3 p.m. news conference, Wright County Sheriff Sean Deringer confirmed that the person in custody is a 67-year-old man named Gregory Paul Ulrich from Buffalo, noting that Ulrich was “no stranger to law enforcement.”

“We have had several calls for service regarding Mr. Ulrich dating back to 2003,” Deringer said to reporters. “Both the Buffalo Police Department and the Wright County Sheriff’s Office.”

Ulrich was arrested at the clinic, according to Buffalo Police Department (BPD) Chief Pat Budke, who was fighting back tears during the conference.

“There is no information at this time that leads us to believe that there is any nexus with domestic terrorism,” Budke also said. “We are very familiar with the suspect.”

Deringer went on to say that a “suspicious package” was found in the corner of the clinic lobby and that the Minneapolis bomb squad was on the scene.

At the same time, the sheriff said that “early in our investigation” they received information that Ulrich was staying most recently at the Super 8 motel in Buffalo and subsquently evacuated and cleared the area, discovering “additional suspicious devices” on the motel premises.

Deringer also noted that they now have search warrants “in hand” and said that his office would cooperate with state and federal authorities in investigating the shooting. Deringer said he believes that Ulrich acted alone.

Budke, while not being able to provide a definitive answer at the conference for the shooter’s motivation, noting that the investigation is still in its early stages, the chief said that most likely the shooting was “targeted at that facility or someone within that facility” given the suspect’s history of conflict.

“There is a history of him being unhappy with health care—with the health care he received,” Budke added.

Regarding those injured in the shooting, Buffalo Hospital president Kelly Spratt confirmed at the conference that five people were hospitalized. Four were sent to North Memorial, and another to HCMC. Spratt said two individuals were first transported to Buffalo Hospital, but the remaining three headed for metropolitan hospitals directly from the scene because of the level of injury.

Spratt had no additional information regarding the condition of any of the victims.

Minnesota Gov. Tim Walz (DFL) had said at an earlier conference that there was an “active shooter situation and some improvised explosive devices.” The FBI and ATF are involved in the investigation because of the explosive devices, he also said at the time.

Prior to the press conference, the FBI’s Minneapolis field office and the bureau’s national headquarters couldn’t be reached for comment.
