A college athlete was arrested Thursday and accused of killing a 63-year-old security guard after police found him wandering naked through the streets of Maui.

Legend Storer, 20, was arrested and charged with second-degree murder, first-degree burglary and indecent exposure, according to online court records. Storer is a freshman at Concordia University Irvine and a member of the university’s NCAA Division II swim team, according to the team’s roster.

He is accused of killing Michael Dyer, 63, of Lahaina, Hawaii, according to the court records. Dyer was working as a security guard at a residential building in Lahaina, on Maui’s west coast, according to news release by the Maui Police Department.

Storer has pleaded not guilty to the charges.

The Maui Police Department did not name Storer but said it received calls about a 20-year-old nude man wandering the streets of the nearby Kahana neighborhood around 3 a.m. on Thursday.

Police said they apprehended the man around 3:30 a.m. and took him to Maui Memorial Medical Center for evaluation. He was “still unclothed and had sustained numerous abrasions” when officers found him, police said.

At about 5:35 a.m., police said they responded to a call about Dyer being found unresponsive. Upon arrival, officers learned from medical personnel that Dyer had died of his injuries at the scene, police said. The press release does not specify the nature of Dyer’s injuries.

After reviewing surveillance footage, police said they determined that the naked 20-year-old man approached the victim’s office at 1:45 a.m. that same morning and “assaulted him before fleeing on foot.”

Authorities then transported Storer to Wailuku Police Station without incident, according to the police department.

Concordia University Irvine did not immediately return a request for comment.

A biography for Storer on his swim team’s website says he swims the breaststroke and sprints and that he is majoring in business finance.
