A former truck driver trainee accused of fatally stabbing his driver trainer is going on trial for first-degree murder in Belton, Texas.

The suspect, Stanley Polk, 46 at the time, of Las Vegas, Nev., was a driver trainee for Werner Enterprises when he was accused of fatally stabbing his driver trainer, Ronald Ruiz, 62, of South Bend, Ind., multiple times on Aug. 27, 2015, at a rest stop off Interstate 35 at 281 south of Salado. Jury selection in the case was expected to begin in the Bell County District Court in Belton, Texas, on Monday.

Polk was arrested the following morning. A Bell County, Texas, grand jury indicted Polk for Ruiz’s murder in November 2015. He has been held in custody on a $1 million bond.

In the initial reporting of the incident, a Bell County Sheriff’s Department spokesman told Land Line that Ruiz was working as a driver instructor for Werner Enterprises. An argument between the instructor and driver trainee turned into a fight, and Ruiz was stabbed by trainee Polk.

Ruiz was airlifted to a hospital, but died overnight of multiple stab wounds.

Polk fled the scene but was later apprehended walking on a frontage road near the Holiday Inn in Salado just before 5 a.m. the day after the stabbing. Police said Polk cooperated with authorities upon his arrest.
