"Attacked without warning in his family’s hotel room by a maintenance worker who was armed and demanding money, Scott Hapgood acted in self-defense to protect the lives of his young daughters and himself," Hapgood's spokeswoman Kelcey Kintner said in a statement Thursday.
"Despite false reports to the contrary, the Hapgoods never called maintenance. Neither invited nor expected, the worker showed up unannounced in uniform at the hotel room," Kintner said.
Scott and the members of his family have been traumatized by the assault they survived and are thankful to be alive.
Hapgood, who works as an account manager with UBS Global Asset Management, had "to seek medical attention to his wounds from the altercation, which included multiple cuts from the knife Mr. Mitchel came bearing," according to a statement by the defense.
"Scott and the members of his family have been traumatized by the assault they survived and are thankful to be alive."
Mitchel never would have considered committing a crime at the hotel because he always had to wear an employee T-shirt and name tag at the luxury Malliouhana resort and thus would have been easily identified, said to his brother Kimon Mitchel, 26.
"He would never try something that dumb. Even if it was possible he would not," Kimon Mitchel said. “Why would someone try to do something like that? It doesn’t make sense. It doesn’t add up. It doesn’t make sense.”
Kimon Mitchel said his brother was well-liked and honest and even refused tips from guests.
“He was a very nice person, and people at the hotel would always have good things to say,” Kimon Mitchel said. “Everyone knew Kenny, everyone knew what type of person he was.”
Hapgood is scheduled for a pre-trial hearing Aug. 22 in Anguilla.
