A state judge has postponed sentencing for admitted hit-and-run driver Chantel Andrade to give her the opportunity to complete substance abuse treatment.

Andrade, 40, was scheduled to be sentenced Wednesday for leaving the scene of a fatal traffic accident and for operating a vehicle without a valid driver’s license.

She pleaded guilty to the charges in November and is asking the court to give her the opportunity to avoid conviction by deferring her pleas.

The prosecutor says he will ask for the maximum 10-year prison term for the hit-and-run charge.

Circuit Court Judge Dean Ochiai postponed the sentencing and instead scheduled a hearing for September to get an update on Andrade’s progress in substance abuse treatment and to set a new sentencing date.

Defense attorney Donovan Odo told Ochiai that Andrade, of Kalihi, is faring well in residential treatment, expects to transition into outpatient treatment in April and could get clinically discharged in October.

Motorcyclist Keith Jantoc died in April when he was struck by a sport utility vehicle in the town-bound lanes of the H-1 freeway near the Kunia on-ramp. Jantoc, 25, of Mililani, died from blunt force injury to the head, neck and torso. He was wearing a helmet.

Honolulu police later found Andrade’s full-size SUV abandoned in a Pearl City parking lot with front-end damage and motorcycle parts stuck in its grille.
