Man pleads guilty in I-17 fatal crash

A truck driver accused of causing a crash on I-17 last fall has pleaded guilty to three counts of endangerment.

The Maricopa County Superior Court says Brian Knoll plead guilty on Tuesday afternoon. Prosecutors say Knoll was under the influence of pain killers when he caused a five-car crash on I-17 last year that killed 22-year-old Paul Troupe.

Knoll is scheduled to be sentenced on October 30 at 1:30 p.m.
