On Friday, it released previously sealed evidence in its case, including the search warrant and arrest warrant affidavits for Reinoehl.Reinoehl was under surveillance Thursday night when he left an apartment and got into a vehicle, officials said. When officers tried to stop the vehicle, shots were fired and the suspect was killed. Reinoehl allegedly pulled a gun, a law enforcement official told ABC News. There were no other injuries, officials said.During the execution of a search warrant issued Thursday for Reinoehl’s residence, Portland police recovered clothing that matched what he was wearing on Aug. 29, at the time of Danielson’s death, according to the district attorney. They also found ammunition that matched the ballistic evidence recovered from the crime scene, authorities said.The shooting death of Reinoehl is still being investigated, said Multnomah County District Attorney Mike Schmidt, who did not share more details on the incident.“We still do not have a full understanding of what led to the death of Michael Forest Reinoehl,” Schmidt said in a statement.“The apprehension of a fugitive, in particular one under investigation for murder, is especially dangerous for law enforcement,” he continued. “I am thankful that no one else was injured or killed during last night’s incident in Lacey, Washington, and I appreciate the coordination between law enforcement agencies throughout this investigation.”Copyright © 2020, ABC Audio.
