Florida divers and boaters are staring at a jaw-dropping accusation: investigators say a man cut off a diver’s air supply during a lobster dispute near Fisher Island.
Quick Take
- Authorities say Michael Joseph Simpson was charged with attempted second-degree murder after the water dispute.
- Reports say he allegedly threatened to turn off the Brownie third-lung system, then did it.
- The defense denies the key act, saying Simpson never touched the tank.
- A judge reduced the original charge after a hearing, but the case is still moving forward.
What Authorities Say Happened
ABC News and NBC reported that investigators say the confrontation began when two boats anchored near the same lobster diving spot off Miami Beach. According to the arrest affidavit described in those reports, Simpson allegedly got angry, said, “I’ll turn the Brownie off if I want to,” then swam to the floating air system and turned off the valve. The diver was said to be about 40 feet underwater when the air supply stopped.
Reporters also said witness accounts and cell-phone video helped place Simpson at the scene and show him leaving the water after the alleged shutoff. NBC News and the Miami Herald both described the same core sequence: a spot dispute, a swim to the air unit, and an alleged intentional shutoff. That repeated detail across outlets gives the accusation strong early consistency, even though the public record still leans heavily on the arrest narrative.
Defense Denial And Charge Reduction
Simpson’s lawyer has rejected the central claim outright, telling reporters, “He never touched the tank.” The defense also says witnesses can back that denial. Miami-Dade Circuit Court Judge Mindy S. Glazer later reduced the case from attempted felony murder to attempted second-degree murder after conferring with both sides, which shows the original charging label did not survive the first court review.
That charge change does not end the case, but it does matter. It shows the legal theory was narrowed before trial testing, and that should matter to anyone who wants facts, not just headlines. At the same time, the available reports do not include the full affidavit, forensic inspection, or sworn testimony. So the public still knows more about the accusation than about hard proof.
Why The Story Hit A Nerve
The case landed harder because Simpson was described as a former member of Miami-Dade’s Boater Safety and Bay Education Task Force. That detail does not prove guilt, but it does invite public anger when a man tied to safety work is accused of putting a diver in danger. For readers who are tired of reckless behavior and weak accountability, the alleged conduct fits the kind of civil breakdown that makes law-abiding people furious.

The wider lesson is simple. A dramatic arrest report can race across the country before the evidence is tested in court. In this case, the accusation is vivid, the defense denial is firm, and the judge has already trimmed the charge. What remains now is the slower part of justice: sorting out whether Simpson really shut off the air, or whether the defense can prove the story is wrong.
