GALLIPOLIS — Following the third armed robbery in Gallia County in less than a week — all at knifepoint — local law enforcement is seeking a suspect and a local business is offering a $500 reward for information leading to an arrest and conviction in the matter.

Brown’s Market, located on Ohio 160 in Spring Valley, was robbed of an undisclosed amount of cash around 7:25 p.m. Thursday evening, according to a report filed by the Gallia County Sheriff’s Office.

The report states that a female clerk was putting away some tobacco products when she heard a male subject tell her to turn around. Upon doing so, she saw a male holding a knife. He asked for the money in the register, at one point saying, “Don’t make me come back there,” even grabbing some cash from the drawer himself.

The suspect had his face covered, but is thought to be a white male. He is around six-feet tall, weighing between 160 and 190 pounds. He was driving a dark colored, four-door car that is possibly green or brown with a larger body manufactured in the mid-1990s.

Brown’s Market is offering a $500 reward for information leading to the arrest and conviction of this man.

Gallia County Sheriff Joe Browning said that his office is looking into whether or not this incident is related to the robbery of the Marathon in Spring Valley last Saturday, but at this point it looks like the two crimes are connected.

Zachary A. Halley, 22, Gallipolis, was arrested in connection with the robbery of the Dollar General last Saturday, and has been housed in the Gallia County Jail since Sunday.

Anyone with information about these robberies is encouraged to call the sheriff’s tipline at 446-6555.
