Full House actor John Stamos can sleep easy – a judge found his extortionists guilty of conspiracy in a Michigan courthouse on Thursday.

Scott Sippola, 31, and Allison Coss, 24, were convicted and sentenced to five years behind bars after the FBI launched a sting operation last year and it was discovered the duo was attempting to release incriminating photos unless Stamos paid them.

The extortionists contacted Stamos via email and demanded $680,000 from the actor in exchange for keeping the photos and information private.
