One person was killed and 11 were injured when a tourist shuttle bus driver confused the gas pedal for the brakes and plowed into a group of people at Honolulu Harbor’s Pier 2 cruise ship terminal this morning, authorities said.

According to Honolulu Emergency Medical Services, paramedics responded to the terminal after 10:20 a.m. and treated victims ranging in age from their 40s to 70s. The injuries ranged from life-threatening to lacerations, EMS said.

A 68-year-old woman was treated for life-threatening injuries and taken to a hospital in critical condition, according to EMS. Honolulu police confirmed that the woman later was pronounced dead.

Police said that at about 10:24 a.m., a 57-year-old male driver had dropped off customers at Pier 2 and was notified by a bystander that his vehicle was moving forward.

He “jumped in the driver’s seat and attempted to stop the vehicle (but) pressed the gas pedal instead of the brakes and collided with two concrete barriers and five pedestrians,” according to a report by the Honolulu Police Department’s Traffic Division Vehicular Homicide Section.

EMS said two men and two women, ranging in age from 55 to 67, were taken to a hospital in serious condition, while a man in his 70s was treated and was in stable condition.

In addition, EMS said, paramedics treated six more adult patients ranging in age from their 40s to 70s at the scene but they declined to be taken to a hospital.

Police said three pedestrians were taken to Queens Medical Center and two others to Tripler Medical Center.

HPD said speed does not appear to be a factor in the collision, but it is unknown if drugs or alcohol were factors. The investigation is ongoing, police said.
