3 arrested in armored car guard killing in Wash.

LAKEWOOD, Wash. — Police near Tacoma, Wash., say three arrests have been made and at least one other person is being sought in the killing of an armored car guard at a Wal-Mart.

Lakewood police spokeswoman Lt. Heidi Hoffman says investigators are not sure whether one of those already arrested might be the man who shot guard Kurt Husted on Tuesday afternoon. The two robbers also took a money bag when they confronted Husted as he left a bank branch at the Wal-Mart.

She says a tip led police to arrest one man Wednesday morning. A man and a woman were arrested Tuesday night and booked into the Pierce County Jail.

Hoffman says surveillance video at the store makes it clear the robbery was planned and the shooter made no attempt to take the money without violence.
