The 14-year-old passenger who died Monday from injuries received in a crash Sunday that killed a 49-year-old Kihei woman was her son, the Maui mayor revealed in a news release today.

“I extend my deepest condolences to the Jouvenat Family and all the loved ones of people who’ve lost their lives on Maui’s roadways,” Mayor Mike Victorino said in a press release today.

Maui police said alcohol may have been a factor in the crash in Kihei that killed Mildred Jouvenat Sunday night and her 14-year-old passenger, who died 2 p.m. Monday.

Police said a gray 2008 Ford F150 pickup truck, driven by a 43-year-old Kihei man, crossed the center line, striking a white 2016 Nissan Versa.

Maui police identified the driver of the Nissan as Mildred Jouvenat of Kihei. Jouvenat died at the scene of fatal injuries.

The 14-year-old Kihei boy received life-threatening injuries and was taken to Maui Memorial, where he died.

The Nissan was traveling south on Piilani Highway when the pickup slammed into it at about 7:24 p.m.

The Nissan struck a third vehicle, a white 2016 Ford Focus, driven by a 74-year-old Kihei woman. She sustained minor injuries and was also taken to Maui Memorial.

The pickup truck driver was taken to the hospital with serious injuries.

A preliminary investigation shows alcohol is considered a factor in the collision, police said. Police said the pickup truck driver was not wearing his seatbelt. All others were.

The deaths are the 13th and 14th Maui traffic fatalities this year compared with 10 the same time last year.
