Steven Michael Lee McComas, 21, was sentenced Wednesday in Anchorage to six and a half years in prison. He pleaded guilty to conspiracy to commit robbery and being a felon in possession of a firearm.

Court documents say McComas' phone was used to order a pizza in Fairbanks on Feb. 9, 2018. That driver was robbed at gunpoint by two people, who took her phone and money. The court documents say McComas was in that car that drove the robbers away.

One day later in Anchorage, another pizza delivery driver was robbed at gunpoint. That driver's phone, money, shoes and vehicle were taken. In both robberies, the suspects wore ski masks.

Anchorage police found the stolen vehicle from the pizza delivery driver and after a chase, they stopped it, finding McComas in the driver's seat. In the car with him, he had a Kel-Tec Sub-2000 9mm semiautomatic rifle, gloves and a ski mask, along with some shell casings.

Because of McComas' three prior vehicle theft-related convictions, he was sentenced to six and a half years in prison, followed by three years of supervised release.
