An employee with David Trapp Sales in Winder was taken to Barrow Regional Medical Center on Feb. 4, 2012, after a co-worker stabbed him, according to a Winder Police Department report.

According to the incident report, the injured employee said he had been joking around with three other co-workers when one grabbed a knife and stabbed him.

Another co-worker transported the victim to the hospital, where a Winder police officer observed a 1- to 2-inch wide stab wound on the victim’s side and three holes in the victim’s shirt where his co-worker, 18-year-old Robert James Cooper of 449 Forest Lake Road in Pendergrass, appeared to have attempted to cut him three times.

One of the employees who witnessed the incident said the victim playfully pushed his co-workers before he was stabbed.

Cooper turned himself in at the Winder Police Department the following day. He was arrested and charged with aggravated assault.
