State police are investigating after an off-duty Waukegan police officer shot and killed her husband at their residence in Waukegan Sunday evening.

The Waukegan Police Department responded around 8 p.m. Sunday to a home in the 2000 block of North Avenue in Waukegan for a report of a shooting.

Waukegan Deputy Police Chief Joe Florip said officers located a male subject that had been shot and a female subject was with him.

The man, a Waukegan resident in his 30s, was transported by ambulance to an area hospital where he died from his injuries.

The woman, a Waukegan resident in her 40s, was identified as a 19-year veteran of the Waukegan Police Department, Florip said.

Florip said that it is believed a domestic incident occurred, which resulted in the off-duty officer shooting her husband.

The woman called 911 after the shooting.

The weapon used in the incident was recovered and identified as the off-duty officer’s service pistol.

The Illinois State Police (ISP) was called to investigate the shooting. The investigation is open and active, Florip said.

The officer has been placed on administrative leave pending the investigation. She is cooperating with investigators.

The Lake County Coroner’s Office has scheduled an autopsy for Monday on the man and his identity will be released after family notification has been made.
