Cotter said during a news conference Thursday that Jarvis and his wife showed up at Graham's office for an appointment Wednesday morning. Jarvis became upset after Graham told them that he doesn't believe chronic pain requires opioid medication. The couple left, but Jarvis — armed with a gun — drove back to the doctor's office about two hours later, Cotter said.
At that point, Graham was on his way to the St. Joseph Rehabilitation Institute a few miles from his office. Jarvis followed him to the institute's parking lot, where the two argued, Cotter said.
“There were two witnesses who were outside and in close proximity,” Cotter told reporters. “Jarvis went to those two witnesses and told them to leave. They saw a gun.”
Jarvis shot Graham, then drove to a friend's home, where he “gave indication that he was no longer going to be around,” Cotter said. The friend, concerned for Jarvis's safety, called 911, but Jarvis killed himself before police arrived.
Cotter said Jarvis's wife did not know that he had driven back to the doctor's office and killed Graham. It also remains unclear whether both the husband and wife were addicted to opioid medications or whether Jarvis wanted the drugs for himself.
