PHOENIX – Yavapai Silent Witness is offering a $10,000 cash reward for information leading to the arrest of a driver suspected of causing a fatal car crash that claimed the life of Sonya Teresa Coronado, an employee of the Maricopa County Attorney’s Office.

On Friday, April 10, 2015, at approximately 1:15 p.m. Sonya was driving her silver Toyota SUV on northbound Interstate 17 when she was involved in a collision at milepost 252, directly across the Sunset Point rest area. Witnesses reported seeing a silver standard single cab pickup truck driven by a male Caucasian pull alongside Sonya’s vehicle and make an obscene hand gesture before driving into her lane in front of her, causing Sonya to take evasive action to avoid being hit. After being forced into the median, Sonya lost control of her vehicle which travelled across the northbound lanes and off the roadway to the east, overturning numerous times. Sonya was transported by helicopter to John C. Lincoln North Mountain Hospital and admitted in critical condition with severe brain trauma. She passed away on April 24, 2015. She was 36 years old.

“Sonya had so much to live for and her untimely death has touched the men and women of the Maricopa County Attorney’s Office very deeply,” said Maricopa County Attorney Bill Montgomery. “We are committed to finding the answers to this tragedy and, if necessary, seeking justice on Sonya’s behalf which is why we are appealing to the public for help in determining the circumstances that led to her death.”

Anyone with information about this incident is encouraged to call Yavapai Silent Witness at 1-800-932-3232. Reports can be made anonymously. A $10,000 cash reward will be offered for information that leads to the arrest of the suspect driver.
