An elementary school principal was charged this week with murder for allegedly driving drunk and killing a woman in a head-on crash in Palmdale.

Mary Noel Kruppe, 35, of Pearblossom, is scheduled to be arraigned tomorrow at the Antelope Valley Courthouse, according to the District Attorney’s Office.

About 6:50 p.m. on Nov. 15, Kruppe was driving a 2014 Jeep Wrangler southbound on 50th Street East, north of Avenue P, when she allegedly veered left into oncoming traffic, causing a head-on collision with a 2010 Mazda driven by 29-year-old Jessica Ordaz of Lancaster.

Ordaz was pronounced dead at the scene, and Kruppe, a principal at Enterprise Elementary School in Lancaster, was taken to a hospital with moderate injuries, according to the California Highway Patrol.

If convicted as charged, Kruppe faces a maximum sentence of 15 years to life in prison.

Prosecutors said they would ask for bail of $2 million.
