There are literally countless possible motives. Nobody on this bbs that I know of has any knowledge of this case and wouldn't have idea more than anyone else. Off the top of my head these are some that I thought about. 1. Anger at a girlfriend or spouse 2. Anger at a workers where the girlfriend or spouse worked 3. Jealousy the girlfriend or spouse was spending too much time with the workers of the Macy's 4. Anger that one of the girls at Macy's rejected him/made of him/laughed at him/was rude to him 5. Anger that one of the girls at Macy's was supposedly rude or insulted the shooters girlfriend or spouse 6. Disgruntled worker 7. Religious fanatic and terrorist 8. Mentally deranged Attention seeker 9. Attempted robbery gone wrong 10. Political disagreement with one or more of the workers at Macy's 11. One or more of the workers at Macy's were going to testify against a friend of the gunman at an upcoming trial 12. One or more of the workers at Macy's were going to testify against a friend of the gunman at an upcoming trialOne or more of the workers at Macy's were going to testify against a friend of the gunman at a trial that already happened 13. Shooter was upset with customer service from one or more workers at the Macy's 14. Being in Washington State, it's possible that he was a member of an Native American Indian Tribe, and was discriminated against by workers at the Macy's. The list could go on and on, and it's pure guess work on my part or your part, or anybody else's part not connected with this case.
Armenians have been planning attacks on US soil for denying the Armenian genocide and aligning themselves with Turkey.
Maybe they were Native Americans, he quantum-leaped from the 1830s, and they were looking for Seahawks tickets last-minute.
Well I guess it's good to see that this is just good old fashioned crazy relationship violence than some kind of terrorism.
