A Lahaina boat captain was ordered to pay $4,000
in fines after pleading guilty on April 30 to negligent
homicide and other charges in the death of a diver who
was struck by an inflatable boat in waters off Lanai two
years ago.
The Maui News reports that Eric Olbrich, 44, of
  Lahaina also was ordered not to operate a vessel within
  a mile of Lanai as part of his one year's probation. He
  was sentenced after pleading guilty as charged to the
  misdemeanor charge of third-degree negligent homicide.
  He also pleaded guilty to the violations of careless operation
  of a vessel, operating a vessel in excess of speed
  restrictions within 200 feet of a diver's flag, operating a
  vessel in excess of speed restrictions within 200 feet of a swimmer and operating a vessel within 100 feet of a displayed
  diver's flag.
The death occurred the morning of July 31, 2011,
  when Lanai resident Alan Amoncio, 51, was freediving
  just outside the break wall at Lanai's Kaumalapau
  Harbor. Amoncio's wife, Kittrick, was diving with him
  when she saw the boat owned by Ultimate Rafting
  quickly approaching the harbor entrance. She was 50
  to 70 feet away from her husband when she saw him
  surface and saw the boat drive over him. Alan Amoncio
  had marked his position with a red diver-down flag
  with a diagonal white stripe, according to court records,
  and he suffered fatal injuries from being struck by the
  boat propeller.
As part of his sentence, Olbrich also was ordered to
  pay $8,483 in restitution and $275 in fees.
