They had been called to respond to a break and enter at his residence.

According to an SIU news release, police were speaking to Abbott when he collapsed.

Emergency medical services then took him to hospital. He was pronounced dead shortly after.

An autopsy was done in Hamilton on Dec. 14.

Two investigators and a forensic investigator were assigned to the case.
