John Charles McLean, 53, was shot and killed on the evening of September 2, 2016, in Cocoa Beach, Florida. He was found unresponsive inside a vehicle parked at 150 Minutemen Causeway with a gunshot wound to the head and was later pronounced dead at a nearby hospital.

McLean had been out with friends that night, including Leonard Nelson Lopez, 58, of Merritt Island. The two men, who had lived on separate houseboats in a marina off Merritt Island and had known each other for at least five months, got into Lopez’s blue 2005 Lincoln Town Car while their wives walked away. An argument between McLean and Lopez escalated and Lopez used a gun to shoot McLean in the head. Lopez was taken into custody near his houseboat shortly after the incident and was booked into the Brevard County Jail Complex on no-bond status, charged with manslaughter.

The Cocoa Beach Police Department, assisted by the Brevard County Sheriff’s Office crime scene agents and the Game Over task force, investigated the shooting. Does anyone have information about McLean, the events that night, or the relationship between the two men?
