An armed robbery of a Tacoma cannabis retailer left a man dead Saturday, police said.

According to the Tacoma Police Department, a man working at World of Weed, in the 3200 block of Portland Avenue East, was found with a life-threatening gunshot wound when officers arrived shortly after 10 p.m.

They attempted lifesaving measures. Firefighters also responded. The man was pronounced dead at the scene.
