CHICAGO (AP) — A Cook County sheriff’s deputy has become the second member of the department to die after testing positive for the coronavirus.

Fifty-three-year-old Deputy Richard O’Brien died Sunday. O’Brien’s death comes three months after he was diagnosed with leukemia.  O’Brien — who worked in the Civil Process Division in Skokie — is the first member of the department to die of COVID-19 complications who did not work in the jail.

The first member of the department to die after testing positive for the virus worked at the jail, where the COVID-19 outbreak has sickened hundreds detainees and staffers and left six detainees dead.
