Two injured in unintentional shooting during gun sale in business parking lot

Two employees of Sharp Communications in Huntsville, Alabama were in the business' parking lot engaging in a private handgun sale when one of the men unintentionally discharged the weapon. The bullet went through one man's hand into the other man's abdomen.
The men were taken to the local hospital for treatment. Their injuries were not life-threatening.
The company's CEO said the sale had nothing to do with Sharp Communications. He also noted that both men were on the clock at the time of the incident and the management was discussing how to handle the incident.
Alabama just passed a new gun law allowing employees to bring loaded guns to the workplace but have to keep them in their vehicle. The law went into effect August 1st.
