A Houston woman who was arrested after a chase at speeds of 100-miles-per-hour through three Central Texas counties Wednesday, was in the Williamson County Jail Thursday charged with evading arrest in a motor vehicle and resisting arrest.

Patricia Freeman, 54, was ordered held in lieu of bonds totaling $27,500.

Investigators don’t know why the woman didn’t stop when a Department of Public Safety trooper tried to pull her over for speeding at around 10 a.m. Wednesday just south of Caldwell in Burleson County, DPS Trooper Jimmy Morgan said.

Nothing illegal was found in the car.

The trooper clocked the woman’s Toyota Tacoma pickup at more than 100 miles-per-hour on State Highway 36 and after she refused to stop, gave chase, authorities said.

The pursuit continued into Milam County, where the woman turned left onto U.S. Highway 79 and drove west through Rockdale and Thorndale and then into Williamson County.

The nearly 30-minute chase ended in Williamson County, after a deputy deployed a spike strip, Morgan said.

The driver slammed on the truck’s brakes and came to a screeching halt before driving over the strip, Morgan said, and Freeman and her male passenger surrendered without incident, he said.

No one was hurt.
