After the victim was able to get off the forklift, she screamed for help and ran away. Turner chased her and stabbed her in the back, then fled, police said.

The victim, who also suffered stab wounds to the left leg, left arm and chest, told police she knew Turner. The victim also confirmed she had a sexual relationship with Turner’s husband.

On Thursday, police said, Turner sent a text message to an office where she had a medical appointment and said she couldn’t keep it because “she would most likely be going to jail that day.”

When a worker in the medical office asked Turner what was going on, police said, “Turner sent her a link to a news story regarding the assault” at the GM plant. The worker took a screen shot of the text messages and emailed them to police.

Turner turned herself in at Wentzville police headquarters about 5:30 p.m. Thursday. She was to be transferred Friday to the St. Charles County Jail, police said. Cash bail was set at $200,000.
