LAS VEGAS (AP) — Authorities in Las Vegas say a 25-year-old woman accused of driving under the influence was going more than twice the speed limit when her vehicle slammed into another car, killing an 8-year-old boy.

A judge on Wednesday granted prosecutors' requests for several more days to obtain blood test results in the felony DUI and reckless driving case against Aylin Alderette-Perez.

The 8:30 a.m. Friday crash killed Levi Echenique and injured his parents, Briejet and Jose Echenique. Two people in a third vehicle also were hurt.

The Las Vegas Review-Journal reports that Alderette-Perez told police she was late for work, and vehicle computer records showed she was driving 103 mph (166 kph) in a 45 mph (72 kph) area.

Witnesses reported that Alderette-Perez's Chevrolet Camaro ran several stop lights before crashing.
