While blood test results have not yet been released in the case of John Victor Noack of Payson, Gila County Attorney Jerry DeRose said he intends to handle the prosecution of the case.
"We are working on the case," DeRose said Monday, "and we intend to present this case to the grand jury. It will be up to them what charges he'll face."
Noack, 53, was the driver of an Arizona Public Service bucket truck that struck and killed three people the afternoon of Aug. 15, just west of Dealer's Choice Road on Highway 260.
According to investigators from the Arizona Department of Public Service, Noack was driving east when he drifted off the right side of the highway, pulled back on to the road at highway speed and overcorrected. Out of control, Noack's work truck spun counterclockwise and slid into the west lane, crashing into a Ford Escort driven by Pauline Ann Jeffrey of Keams Canyon.
Jeffrey, her cousin Karen Begay, and Begay's 2-year-old son were killed instantly in the crash. Begay's 4-year-old daughter, Shavanah Tsipai, was the only survivor, suffering a broken left leg and minor cuts and bruises.
Noack was uninjured in the wreck, and was booked into the Gila County Jail on three counts of aggravated assault.
He was released after posting a $60,000 bond.
APS District Manager Jim Spencer said Noack remains on suspension.
