( CNN ) -- How do you swipe $ 7 million in toys , electronics and other stuff without anyone noticing ? Apparently , in Mom 's flowing black dress , according to federal prosecutors who have charged three members of an Illinois family with transporting stolen property across state lines . They 'd been at it for a decade , prosecutors said . Prosecutors say Lela Bogdanov stuffed merchandise in the blue lining of her big black dress , then walked out of the stores -- often with family members staging a diversion to draw the attention of employees . The family -- Lela Bogdanov , her husband Branko Bogdanov , both in their 50s , and daughter Julia Bogdanov , 34 -- then sold many of the items to a fence who unloaded them on eBay , prosecutors claim . The alleged fence is cooperating with authorities and was not named by prosecutors . The couple netted more than $ 4 million from the sale of stolen goods with a retail value of more than $ 7 million , according to the U.S. Attorney 's office in Chicago . The Bogdanovs ' decade-long scheme began to unravel , prosecutors say , when loss-prevention experts at Barnes and Noble and Toys R Us noticed huge amounts of merchandise had gone missing . They found an eBay account selling the same items in similar quantities as those allegedly stolen from their stores . Secret Service agents arrested the trio Wednesday at their Northbrook , Illinois , home . They 'd just returned home from a trip to Oklahoma , Texas and Louisiana , during which prosecutors say they stole more items . If convicted , they face up to 10 years in prison , a $ 250,000 fine and restitution .
