Maui police said they are investigating whether alcohol, drugs, speed and improper seat belt use were involved in a single-vehicle wreck that left a 24-year-old Waikapu man dead on Friday.

A police news release said James R. Sanchez was killed when a 2003 Toyota pickup truck he was riding crashed on Old Makena Road, four-tenths mile south of Kaukahi Street in Wailea, at 11:25 p.m. Sanchez died at the scene, police said.

Police said two other people were in the vehicle when it crashed, a 28-year-old Ha'iku man and a third person, who is reported to have left the scene and is now being sought by investigators. The Ha'iku man was injured, but was treated and released at Maui Memorial Medical Center.

This is Maui's 12th fatality this year, compared with 14 at the same time last year, police said.
