A South Florida man faces an attempted murder charge after investigators accused him of intentionally tampering with a dive buddy’s scuba equipment during an offshore excursion, cutting off the victim’s air supply 200 feet underwater. According to the Monroe County Sheriff’s Office, 41-year-old Bryan Sean McMenamin was arrested following the incident off the coast of Islamorada.
The Incident off Islamorada
The confrontation unfolded beneath the surface on a Saturday dive trip near the Florida Keys. According to the arrest affidavit released by the Monroe County Sheriff’s Office, McMenamin and the victim were diving together when an underwater dispute erupted. Investigators state that McMenamin deliberately manipulated the victim’s regulator and air supply apparatus, cutting off the breathable air source at a depth of roughly 200 feet.
The victim managed to share air with another diver in the group and safely ascended to the surface, avoiding fatal injuries. Charter boat crew members and fellow divers reported the dangerous encounter to authorities immediately upon returning to shore.
Charges and Legal Proceedings
Monroe County deputies took McMenamin into custody following interviews with the dive crew and witnesses on the vessel. According to jail records, he was booked into the Monroe County Detention Center on a single count of attempted second-degree murder.
Attempted murder charges in Florida carry severe penalties, including up to life imprisonment upon conviction. Prosecutors are reviewing statements from the boat captain and surviving divers to build the case. Court records show McMenamin is being held pending a bond hearing.
Scuba Safety and Equipment Protocols
Diving experts emphasize that standard recreational scuba limits rarely exceed 130 feet, making a 200-foot descent a specialized technical dive requiring advanced training and strict adherence to the buddy system. According to the Professional Association of Diving Instructors (PADI), the foundational rule of scuba diving requires divers to remain paired and assist each other in emergencies, making intentional equipment interference an extreme violation of standard maritime safety protocols.
Law enforcement officials continue to investigate the motive behind the underwater dispute. Anyone with additional information regarding the charter trip or the relationship between the individuals involved is encouraged to contact the Monroe County Sheriff’s Office Criminal Investigations Bureau.
