The woman whose pickup caused a fatal collision on the Old Glenrock Highway last month said she passed out before the crash, according to court documents.

Cassandra Wickett was driving eastbound about 10 miles west of Glenrock when she saw warning signs about the construction zone and stopped cars, she told Wyoming Highway Patrol troopers shortly after the crash about 3 p.m. Wednesday, Aug. 24, according to affidavits for search warrants filed with the Natrona County Circuit Court on Monday

The first trooper at the scene talked to Wickett, who said she was talking on her cell phone with Rocky Mountain Power, hung up, passed out and then felt the crash.

She told that trooper, and another one who interviewed her at the Wyoming Medical Center, that she was anemic and felt dizzy at work earlier that day.

The pickup was traveling about 70 mph. It caused a chain reaction crash by hitting a car with Glenrock resident Leoda Cain and three other stopped vehicles.

Wickett, Cain and other occupants in the cars were taken to the Wyoming Medical Center. Cain died five days later.

At the hospital, Wickett told another trooper about the call with Rocky Mountain Power. She showed him her phone with the times of that call and texted messages received at the same time, 2:57 p.m. It was unknown when Wickett looked at the text messages. A time stamp showed she called her mother at 3:05 p.m.

Wickett told the trooper she saw the warning signs about a half-mile before the construction zone, saw the stopped vehicles, and knew she needed to slow down. She did not remember braking, but did remember the collision.

The phone records could help investigators to better determine the time of the crash and whether phone use may have been a factor in causing the crash.

The medical records could help determine how the crash occurred, how the occupant was injured, and the extent of the injuries, according to the affidavit for the warrant at the WMC. "Combined, all of this information can help in recreating the crash and is vital in the prosecution of vehicular homicide cases."

Wickett, who was 19 at the time of the accident, initially was charged with following too close.

The search warrants did not give details about what investigators found in the cell phone or the medical records, but offers information that the Converse County Attorney may use if he decides to prosecute the case.

County Attorney Quentin Richardson said he is still waiting for the results of the investigation by the Wyoming Highway Patrol.
