An 87-year-old Haiku, Maui, woman died over the weekend after she was hit by a sedan driven by her 11-year-old grandson.

The incident happened as the quarterly social for the 442nd Veterans Club was breaking up at the Nisei Veterans Memorial Center in Kahului.

Police said the boy was reversing a Mitsubishi Galant out of a parking stall at about 12:50 p.m. as the woman was standing nearby when the driver’s side door hit the woman and knocked her to the ground.

The car continued backing up until it hit a Honda Element stopped to the rear.

Police said the woman was taken to Maui Memorial Medical Center in critical condition. The boy, of Wailuku, and the driver of the Honda were not hurt.

Hiroshi Arisumi, who was attending the event, said an acquaintance called him on Sunday and told him the woman had died. A police spokesman was not available Sunday to confirm.

Arisumi said the woman, whom he only knew by last name, Saito, was friendly and her late husband had served with him in the 232nd Combat Engineer Company, part of the famed 442nd Regimental Combat Team in World War II.

He said he didn’t see the incident, but heard from others that the boy was trying to start the car when it began moving.

“He wasn’t driving,” he said. “He just started the car and the thing moved.”

He said when he went outside, the woman was already lying on the ground.

“It’s really too bad,” he said.
