The main suspect accused of two armed robberies in Natrona County earlier this summer has entered a plea in court.

Twenty-one year old Nathaniel Neuman has pleaded not guilty to two counts of aggravated robbery, one count of conspiracy to commit aggravated robbery, and one count of possession of a controlled substance - marijuana.

Investigators with the Casper Police Department say in late July, Neuman robbed the Loaf N' Jug store at 4603 W. Yellowstone Highway in Mills, and about a half-hour later the Loaf ‘N Jug at 938 S. Poplar St. in Casper.

The clerk in Mills told police a male wearing a hoodie was carrying a silver weapon, believed to be a knife.

The robbery failed after the clerk told him to get a job and he left.

About half an hour later, he tried again at the store on Poplar Street, and got away with $100.

Neuman had an accomplice, 20 year old Katherine Good, who was spotted on closed circuit video at one robbery, and when interviewed by police, she said she was a lookout and getaway driver for Neuman, who committed the robberies.

Neuman is being held on $50,000 bond awaiting trial, and could face between five-to-25 years in prison on each of the aggravated robbery charges, and the conspiracy charge if convicted.

Good is also facing charges connected to this case, and is awaiting trial.
