The search warrants make it clear what the agents are looking for. They showed up at John Mulinski's Covington home Thursday afternoon.
They want computers, bank records and employee records to see if Mulinski has been withholding payments to Labor and Industries, the Employment Security Department and the Department of Revenue.
Mulinski has had a difficult relationship with L&I. In fact, he's been cited no less than 11 times for contracting without a license.
Here's how the state's case is setting up this time:
The state claims Mulinski hired employees to work on the homes of Bellevue's Clinton Jones, Ryan and Liesl Brown of Woodinville, and Michelle Young of Black Diamond.
All of them have told KING 5 that Mulinski either did shoddy work or took the money and didn't finish the job.
Since 2007, Mulinski hasn't told the state about any employees working for him. But at the same time, three people who say they were his employees accuse him of owing them more than $21,000.
The state says Mulinski has been uncooperative and has made no attempt to contest or settle the wage complaints.
If Mulinski or his wife Shannon is convicted of intentionally evading payment of his L&I premiums, they could go to jail.
The last time we saw Mulinski he was heading to jail for violating the terms of his release - on three criminal counts of contracting without license.
Mulinski made bail in that case, but he's in a world of trouble. There are also 13 criminal counts of construction malfeasance against him in California.
