Two sisters have been charged with leaving their children alone at the Lego store at Eastview Mall. Francisca Lopez of West Henrietta and Yaquelina Rosario De Hernandez are both charged with endangering the welfare of a child. Ontario County sheriff's deputies say they allegedly left their two children, ages 7 and 9, unattended in the store for two hours yesterday while they shopped elsewhere in the mall.Store employees contacted mall security. The parents were paged over a mall loud speaker but did not reply. They were charged when they returned to get the children. A few weeks ago, a Pittsford mother was charged for leaving her 10-year-old son alone at the same store.
