A 20-year-old Hilo man pled guilty to negligent homicide in U.S. District Court on June 14th. The charge stemmed from an incident in which he caused a crash in the park that killed his passenger. Julien Quiocho pled guilty as part of a plea agreement with the prosecutor that calls for a 24-month prison term. If the judge imposes a higher sentence in September, Quiocho will be free to withdraw his guilty plea. The maximum prison term for first-degree negligent homicide is ten years. The case was investigated by the National Park Service with assistance from the Hawaii Police Department and FBI and was prosecuted by the United States Attorney's Office for the District of Hawaii. Quiocho was the driver of a pickup truck on Highway 11 on June 12, 2011 when the truck left the roadway and crashed into a lava field. Quiocho and his passenger, 20-year-old Bryson Areola, also of Hilo, were thrown from the truck. Areola was pronounced dead at Hilo Medical Center. Blood taken from Quiocho at the hospital showed he had a blood alcohol content of 0.13.
