LAS VEGAS (AP) - O.J. Simpson claimed that when he took items from a pair of sports memorabilia dealers back in 2007, he was only taking what rightfully belonged to him. But an attorney representing the families of his ex-wife and her friend are claiming some of the stuff wasn't Simpson's at all. David Cook is a lawyer who has been trying to get Simpson to make good on the $33.5 million he's liable for in a civil judgment that found he was responsible for the deaths of ex-wife Nicole Brown Simpson and Ronald Goldman. Cook claims Goldman's father still has still has ownership rights to nine "game" footballs, should they ever be sold.
