Stolen Paycheck

Hello, posting my first question here regarding a recent event for my father.

This is in King County, WA.

My dad just informed me this weekend that someone got into his employee account with a community college and changed his direct deposit account. As a result, his last paycheck was stolen. He immediately alerted payroll but was told there’s nothing they can do besides file a police report. Since payroll had already paid him they cannot reissue another check.

He has filed a police report and they’re supposedly working with the bank to track down the owner of the other account. The officer in charge of the case has asked my dad if he wanted to appear as a witness and testify but he stated he only wants his money back.

At this point there is probably nothing for us to do but wait for law enforcement to conduct the investigation. Does anyone have any recommendations for what my dad can do in the meanwhile besides changing his passwords and keeping an eye on his credit and bank accounts?

Thanks!
