Police are investigating a deadly single-vehicle crash in Wailea that killed a 21-year-old Kihei woman.

She was identified Monday as Rhendie M. Hepa.

Shortly after 7:05 p.m. Sunday, police said, Hepa was traveling north on Wailea Alanui Drive near Malukai Lane in a blue 2006 Toyota Tacoma pickup truck.

The vehicle struck a raised curb on the shoulder of the roadway while negotiating a right curve. Police said the truck then climbed the curb and slammed into a tree.

Hepa was transported in critical condition to Maui Memorial Medical Center, where she later died.

Police said she was not wearing a seat belt at the time of the crash.

This was Maui County’s 15th traffic-related fatality this year, compared with 21 at the same time last year.
