MORELAND, Ga. -- A subcontractor who had gone to a construction site in Newnan County to install drywall was shot to death, and the project's builder has been charged with murder.

The builder, Richard Jason Veitch, 28, said the shooting Saturday morning was not intentional. On Monday, a magistrate judge ruled against reducing the murder charge to involuntary manslaughter.

Veitch said he had been staking out the property because of a series of thefts. Coweta County Sheriff Mike Yeager said Veitch spotted a truck driving onto the property, and told deputies he did not recognize the men.

Yeager said Veitch called 911, but the shooting took place before officers arrived. Deputies said Gaston Gonzalez, of Norcross, was killed when Veitch jabbed a gun into the man's neck and it discharged.
