According to the Carrollton Police Department (CPD), William Gomez, 57, and his two grandchildren were reported missing around 8:15 p.m. Sunday after Gomez told family members he was taking them to the mall in a nearby town but hadn't returned six hours later.
CPD says Gomez accessed the bank account in Little Rock shortly before 8:00 a.m. Monday, and Little Rock authorities are now assisting in the search.
Family members told police that Gomez suffers from a condition that causes memory loss and does not have his cellphone with him.
Gomez was last seen possibly wearing a blue shirt and black pants, and was driving a white Jeep Grand Cherokee with Texas license plate number DH1-Y337.
His grandson Marcus Gomez, 7, was last seen wearing a white t-shirt, cream-colored shorts and black Velcro shoes.
His granddaughter Dominique Gomez, 8, was last seen wearing blue pants and a floral shirt, according to police.
