Lake County Sheriff’s Detectives conducted a comprehensive investigation into the murder of William Martys, age 59, of Antioch Township. Sheriff’s detectives determined Martys’ next-door neighbor, Ettore Lacchei, 79, had a variety of perceived grievances with Martys.

While Martys was utilizing a leaf blower in his yard on Wednesday, April 12, 2023, Lacchei approached him. Lacchei argued with Martys, and during the argument Lacchei allegedly shot Martys in the head.

Lake County Sheriff’s detectives recovered the firearm likely used in the murder, which was located near Lacchei’s property line.

Following a search warrant that was conducted on Tuesday, April 25, 2023, Lacchei was arrested without incident at his home. After reviewing the facts and circumstance of the incident, the Lake County State’s Attorney’s Office approved the charges of two counts of first-degree murder.

Lacchei remains held in the Lake County Jail pending an initial court hearing.

“Our condolences go out to the family and friends of William Martys, who was senselessly murdered. The members of the sheriff’s office are relentless when it comes to seeking justice for victims. The members of our Criminal Investigations Division have been working around the clock to bring Mr. Martys’ murderer to justice, and I am happy Mr. Martys’ family can begin the closure and healing process.”

— Sheriff John D. Idleburg

Lake County State’s Attorney Eric Rinehart said, “I am proud of the work of the Sheriff’s Office, our First Assistant Lauren Callinan, and Chief of Criminal Jeff Facklam who worked closely with detectives on this investigation. Once again, easy access to firearms has turned a dispute into a deadly crime. We will support the victims and seek justice in the court rooms.”

The Lake County Sheriff’s Office thanks the Antioch Police Department and Lake County Major Crime Task Force for their assistance in this investigation.

All defendants are presumed innocent unless proven guilty in a court of law.
