East Moline, IL, Police Sgt. William "Billy" Lind and the man now accused of trying to kill him had encountered each other about two and a half hours before the Monday incident, police and court records show.

Adrian W. Rogers, 52, of East Moline, is charged with attempted murder and aggravated battery, according to Rock Island County court records. Police and the county prosecutor say Rogers struck Lind in the head, causing severe injuries, including skull fractures.

Rogers then left Lind lying unconscious in or near the street, police said, adding that the officer's body camera captured the violence, the Quad City Times reports.

About 20 minutes after a fire that Rogers is accused of setting, the suspect walked into the East Moline Police Station and happened to speak with Sgt. Lind. This was about an hour before Lind learned Rogers was a suspect in the arson and more than two hours before Lind was attacked and critically injured.

At last report, Lind’s injuries were considered life threatening and he remained in critical condition at a Peoria hospital, where he was transported for advanced treatment of his head injuries.
