Three Natrona County men alleged to have taken part in a mid-April armed robbery of a Casper liquor store are behind bars.

Prosecutors allege 30-year-old Pete White, 20-year-old Shannon Mares and 20-year-old Arthur Brown worked in tandem to rob Moonlight Liquors on April 14.

According to court documents, both Brown and Mares entered the store through a sliding drive-up door. Brown then threatened an employee and two victims with a semi-automatic handgun while Mares acted as a look-out and made gestures at customers outside the store with a stick.

White allegedly provided the handgun and clothing used by Brown and Mares during the robbery.

After the robbery, prosecutors say both Mares and Brown were chased out of the store by an employee before disappearing behind an apartment building near 10th Street. Investigators say White lived at an E. 10th Street residence.

All three men were charged with several felonies, including aggravated assault and armed robbery.

White, Mares and Brown face up to 25 years in prison on each felony charge.

Mares and Brown are being held at the Natrona County Detention Center on $50,000 bond. White, who has several prior convictions, is being held on $100,000 bond.
