A man who opened fire at a Minnesota health clinic, killing one staff member and wounding four others, previously threatened to carry out a mass shooting at the facility, according to a police report obtained by The Associated Press.

Gregory Paul Ulrich, 67, was arrested in Tuesday's attack at an Allina clinic in Buffalo, a community of about 15,000 people roughly 40 miles northwest of Minneapolis. He remained jailed in Wright County on Wednesday and was expected to appear in court Thursday.

County Attorney Brian Lutes said he would charge Ulrich with second-degree intentional murder, four counts of attempted first-degree premeditated murder and possession of explosive devices.

The deceased victim was identified by Allina Health on Wednesday night as Lindsay Overbay, a medical assistant who had worked for the company since November 2018. 

"The loss of Lindsay is traumatic for all who knew and loved her," the company tweeted. 

Allina also identified one of the surviving victims as Sherry Curtis, who has worked as a licensed practical nurse at Allina Health since 2013. It did not identify the three other victims. 

Ulrich has a long history of conflict with medical clinics in the area and had been unhappy with the care he had received, Buffalo Police Chief Pat Budke said.

According to a police report, Ulrich threatened to carry out a mass shooting at the clinic in October 2018, with a doctor telling investigators that Ulrich had talked about "shooting, blowing things up, and practicing different scenarios of how to get revenge." He said Ulrich told him he dreamed about exacting revenge on the people who "tortured" him, referring to issues he had with back surgeries and the medication he was prescribed for them.

Ulrich told police he had just been telling the doctor about his dreams and that he wouldn't actually do anything, and police took him for a mental health evaluation at a facility in Monticello, the report said.

Allina medical staff believed Ulrich might act on the threats and filed paperwork barring him from the company's property, which police delivered to his home the next month.

A criminal charge of violating a harassment restraining order was filed a couple of weeks later. The nature of that violation isn't clear in court papers, but orders filed in that case in 2018 and 2019 prohibited Ulrich from having contact with a man whose name matches that of the doctor named in the police report. It wasn't known Wednesday if the doctor was among the victims of Tuesday's attack, and a call to his home number rang unanswered.

In a December 2018 restraining order obtained by CBS News, the man said Ulrich "stated that killing one individual wouldn't be enough and that mass violence at medical clinics and hospitals and that his intent was to create enough of a sensation to get public recognition that would warrant at least 30 years in jail and possibly a straitjacket." 

"He further stated he had practiced different scenarios and he was testing how to get through security with a length of steel since he knew he only had seconds after getting past security to achieve his goal," the order alleged. 

The charge of violating the restraining order was dismissed last April when the prosecutor said Ulrich was found "mentally incompetent to proceed."

One of the victims was discharged on Tuesday. The conditions of two of the three who remained hospitalized Wednesday were upgraded from critical to fair condition. The third remained in critical condition.

During a search of the clinic, investigators found a suspicious device and evacuated the building, Wright County Sheriff Sean Deringer said.

It was not immediately clear whether that device exploded, but TV footage showed several shattered plate-glass windows at the clinic. Deringer said suspicious devices were also found at a local Super 8 motel where Ulrich had been staying, and there were at least two shattered windows there as well.

Deringer said Ulrich was well known to law enforcement before the attack, and there were calls for service dating back to 2003.

Court records for Ulrich list a handful of arrests and convictions for drunken driving and possession of small amounts of marijuana from 2004 through 2015, mostly in Wright County, including two convictions for gross misdemeanor drunken driving that resulted in short jail sentences.

A court services agent who conducted a pre-sentence investigation wrote in a June 2019 filing that he had just learned that Ulrich had applied to police for a "permit to purchase" — apparently meaning a permit to buy a gun — but had not yet been approved. The agent said he "highly recommended" that Ulrich "not be allowed to have use of or possession of any dangerous weapons or firearms as a condition of his probation."

Ulrich also had raised concerns at a local church. According to an August 2019 update on the Zion Lutheran Church's website, the church said it had obtained a no trespassing order for Ulrich after the pastor received a disturbing letter. Church staff were given a picture of Ulrich and told to call 911 if he appeared on any of the church's properties.
