William Martys, 59, was found dead in his Antioch driveway on April 12, 2023, after suffering a gunshot wound to the head. The shooting occurred around 7:35 p.m. in the 40700-block of North Black Oak Drive in Antioch Township. Martys had been using a leaf blower in his yard when a dispute began after his 79-year-old next-door neighbor, Ettore Lacchei, approached him; investigators say the two argued and that Lacchei allegedly shot Martys.

Employees from Martys’ construction company arrived shortly after the shooting and called police. Martys was taken to Advocate Condell Medical Center in Libertyville, where he was pronounced dead. The Lake County Sheriff’s Office arrested Lacchei on April 26, 2023, charged him with two counts of first-degree murder and held him without bond. Investigators say Lacchei had a history of conflicts with Martys, including a prior incident in which Lacchei pulled a gun, and officers located what they believed to be the murder weapon near Lacchei’s property line.

The case was not treated as a stand-your-ground matter because Martys was on his own property. Lacchei appeared in court the day of his arrest and was ordered held without bond; further proceedings were scheduled for May. Does anyone in the Antioch area have information about tensions between the neighbors or witnessed the April 12 confrontation?
