3rd defendant sentenced in Round Rock robbery

PHOENIX - A man has been sentenced to more than four years in federal prison for holding up a northern Arizona trading post.

Federal prosecutors say 22-year-old Garrison Gorman was sentenced to a 51-month term Monday in U.S. District Court in Phoenix.

Authorities say Gorman and two co-defendants entered the Round Rock Trading Post on the Navajo Nation on July 7, 2010.

One of the co-defendants allegedly pointed a rifle at the store owner behind the counter and demanded cash and cigarettes.

Authorities say the robbers fled on horseback and stashed the rifle in a nearby wash. The weapon was later recovered by tribal police.

The other two co-defendants have already been sentenced.
