Fox Lake officer's killing investigated as homicide or suicide: report

Publicly, the spokesman for the investigation, Detective Christopher Covelli of the Lake County sheriff’s office, repeated Monday that authorities are looking at every theory but that they are still pursuing this as a homicide. Speaking on condition of anonymity, though, multiple sources close to the investigation said one of the theories being examined is whether the gunshot wound that killed the officer was self-inflicted. Covelli said the Lake County Major Crime Task Force continued Monday to follow up on leads as they await the results of DNA, gunshot residue and ballistic tests being conducted at local, state and federal laboratories. Every theory is being looked at. Nothing has been eliminated at this point, Covelli said.
