Couple Convicted of Trying to Extort John StamosA Michigan couple were convicted Thursday of trying to extort $680,000 from actor John Stamos by threatening to sell old photos of him with strippers and cocaine to the tabloids unless he paid up.

Allison Coss, 24, and Scott Sippola, 31, both of Marquette, were found guilty in federal court of conspiracy and using e-mail to threaten a person's reputation - charges that could land them in prison for up to five years.

Police arrested the two in a sting in December at an Upper Peninsula airport after Stamos reported being the victim of an extortion attempt.
