Police are continuing to investigate the background of Adam Bergseth, 37, the man who was killed by Danny Hughes, a Marionville police officer on Saturday June 30.
Acting on a tip, Marionville Police Chief Mark Webb requested Springfield investigators check a trash receptacle at the Springfield home Bergseth was renting. Decomposing remains were found in the trash outside the home.
"At that time, we weren't sure if they were animal or human," Webb said.
On Friday, Springfield authorities confirmed that the receptacle contained human remains, likely belonging to a woman. Investigators believe they have tentatively identified the victim.
"At this time, we are awaiting the results of forensic testing," said Sgt. Matt Brown, public information officer with the Springfield Police Department. "Those can take weeks or months to complete."
"We aren't sure what led him to Marionville," said Webb. "Our office received a call from someone reporting a woman was being held against her will at the Applelane Apartments. Upon arrival, Officer Hughes encountered the subject, Adam R. Bergseth, who approached the officer in a threatening manner while wielding scissors."
Hughes shot and killed Bergseth. That incident is still under investigation by the Missouri State Highway Patrol. The officer remains on paid administrative leave.
"We may never know what brought him to our community," Webb continued. "Once he was confronted by the officer, he must have figured it was a 'now or never' scenario and he had nothing to lose."
In the meantime, investigators are backtracking Bergseth's last known whereabouts, including Republic and Bolivar in Missouri and the state of Florida.
"Looking for possible links to other areas is in the scope of our investigation," Brown said.
Investigators collected several pieces of evidence at the Springfield residence for further investigation.
