Over the weekend, "Shark Tank" judge Kevin O'Leary's boat was involved in a fatal crash that left one man dead and one woman critically injured. The accident, which occurred around 11:30 p.m. on Lake Joseph in Ontario, supposedly involved O'Leary's smaller boat hitting into the larger one. Reportedly, one of the watercrafts went directly over the other, which caused a 64-year-old male passenger to be struck in the head, resulting in his immediate death.

According to TMZ, the owner of the larger boat stated there was enough light available to be able to identify the people on the smaller vessel, which they revealed to be O'Leary and his wife, Linda O'Leary.

The smaller of the two vessels was called a "tow boat" by Detective Inspector Martin Graham when speaking to My Muskoka Now. The detective also stated that one of the boats had "definitely" been moving at the time the crash took place, but it has not been officially determined if both had been in motion.

The television personality, who calls himself Mr. Wonderful, is said to have immediately left the scene following the event. For his part, O'Leary said the people on the other boat in the interaction were the ones who in actuality fled the scene, which presents conflicting reports of what happened. A critical piece of the investigation is said to be surrounding whether the larger boat had its lights on, but O'Leary told TMZ that it was the other watercraft that did not have their lights on instead of his own.

A representative for the businessman said his wife was the one driving at the time. However, she is said to have passed a DUI following the crash. A third person, who has since been released from medical care, was also reportedly on the boat.

At this time, O'Leary says he is "fully cooperating with the authorities." Police are said to be investigating the cause of the accident and determining whether alcohol played a role, reports Business Insider.
