A deputy responded to a report of an armed man in a pickup in the parking lot of a Walmart store in Puyallup, Washington.  A shootout occurred, and the man was killed.

From an article and news video:
Pierce County deputies say witnesses called to report a man with a gun inside a pickup truck.
When deputies arrived, the man allegedly fired one shot. It wasn't immediately clear which direction the man fired. Deputies fired back.
The man was killed, although it's not immediately clear if he was hit by deputies or if he shot himself.
