County Sheriff's Department said the area was full of workers at the time, and the suspect pulled his gun out."He went into one of the local businesses and started harassing and assaulting the employees at that business by pointing his handgun at them," Boese said.All employees at the construction site were later evacuated, sheriff's officials said.Officials confirmed the scene came to a peaceful resolution after the suspect was in contact with crisis negotiators and surrendered to sheriff's deputies.
