A security guard working for a company under contract with Entergy to protect transmission lines over floodwaters was killed Monday, and his roommate was charged in the shooting.

Vicksburg police Lt. Bobby Stewart said Michael Justin Tornero, 26, of Houston, was shot once in the neck by a semi-automatic handgun at about 5:54 p.m. He said Tornero was taken to River Region Medical Center. Warren County Coroner Doug Huskey said Tornero was pronounced dead at 8:31 p.m.

Stewart said officers arrested Tornero’s roommate, Daniel O’Neil Dodd, 28, of Tyler, Texas, just after the shooting at their motel room at the Econo Lodge at 3959 E. Clay St. He said Dodd was being held without bond at the Warren Count Jail pending an initial appearance today in Vicksburg Municipal Court. Stewart said Dodd would be charged with manslaughter with culpable negligence because they were playing with the guns in the motel room.

He said Dodd and Tornero were employed as security guards by International Security Agency of Houston. The company has a contract with Entergy to prevent people from launching boats from U.S. 61 South, LeTourneau Road and Warrenton Road near the Baxter Wilson power plant.

He said the men have been in Vicksburg since May 10. Tornero, Stewart said, had been employed by International Security Agency for about three weeks.

The police report said Tornero was hit in the neck, Stewart said. He said police found Tornero lying on a bed.

The killing was the second in the city this year.
