Arrest Made in Deadly Motorcycle Collision

A woman from Palmdale, CA, was arrested on suspicion of vehicular manslaughter concerning a crash that took the life of 28-year-old motorcyclist named Dale Zack. Oliva Amayo Mendoza, age 34, was arrested on the morning of Wednesday, February 1st, because she was suspected of having committed misdemeanor vehicular manslaughter with gross negligence. The arrest was the result of an investigation by traffic detectives that lasted one year.

According to arrest papers, her bail was set at $25,000. The charge of vehicular manslaughter arises from a deadly motor vehicle crash that took place on or around February 12, 2016, at the Highway 14 off ramp in the southern direction for Placerita Canyon Road and Sierra Highway.

Mr. Zack’s motorcycle struck a car on Sierra Highway in Newhall. He was headed in the northern direction on the highway and was nearing the Highway 14 off ramp at Placerita Canyon Road when his motorcycle crashed into the car.

In this case, the responsible party was held accountable for the deadly crash involving a motorcyclist, but in far too many other collisions, the motorist who should have been held liable faced no charges.
