A Casper man is accused of robbing two people while using a weapon.

Thirty-seven year old Brian Lujan has pleaded not guilty to two counts of aggravated robbery with a deadly weapon, one count of child endangerment meth and one count of possession of a controlled substance.

Investigators with the Casper Police Department say in early August, the first victim stopped by Lujan's house.

The victim told them when both were in a vehicle, Lujan pulled out what appeared to be a black handgun, hit the victim in the head and told him to give him his money, which he did.

Later that evening, another victim said he was with Lujan on North Wolcott Street in Casper, when an argument started and Lujan pointed a knife and took a cell phone.

When interviewed Lujan told police that he had pointed a pocket-knife at both victims when he robbed them.

He also said he had used methamphetamine and marijuana.

Officers later obtained a search warrant and found drug paraphernalia at Lujan's residence.

Investigators learned that Lujan has a child, but it was unclear if the child lived with him.

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