The incident occurred about 12:50 AM on I-94 near the Stoney Island feeder, according to The Chicago Tribune. He was found unresponsive in his vehicle while parked on the side of the road. He was transported to Advocate Trinity Hospital, where he was pronounced dead at 1:06 AM.
Captain Lavoy was a 5th District Supervisor for the Calumet District. Police said that he may have suffered a cardiac-related event. There were no signs of trauma, and the case is still under investigation.
Chicago PD Supt. Eddie Johnson spoke of Captain Lavoy saying, "We will never, ever be able to replace him, but Jimmy you are and forever will be part of the Chicago police family. I pledge to you that we will always be there for you, and we will never forget what he contributed to the city of Chicago.
"Police officers are people too, people look at us like machines and robots and they want us to be perfect and we're not, we're people. That incident...humanized the police department. The majority work hard for CPD. Jimmy was definitely that guy. He had a great spirit. All of us knew and worked with him really well."
This hero leaves behind a wife and two children.
Our thoughts and prayers are with the family of Chicago Police Captain James Lavoy, both blood and blue. Godspeed, sir, we will take the watch from here. Thank you for your service.
