A search of Leaf and his pickup truck turned up 28 oxycodone pills, a narcotic for which Leaf does not have a prescription, Hickman said. The label on an empty prescription bottle also found in Leaf's golf bag was made out to an acquaintance, who told police that Leaf entered his house without permission on Thursday and stole the bottle, which contained about 15 pills.
Hickman said police don't know where the other 13 pills came from.
"Leaf eventually admitted to stealing some Oxycodone pills from the associate whose name was on the empty prescription bottle," Hickman wrote in his statement.
Hickman said authorities believe Leaf may have broken into other homes over the past 1 ½ years in search of prescription drugs and is asking those victims to come forward.
Leaf has not returned calls or text messages seeking comment and a message left at his parents' phone number was not returned. He released a statement through his publicist after his first arrest on Friday that says he has "made some mistakes and have no excuses" but that he is "confident that there will be further understanding when the facts are revealed."
Leaf, a former standout quarterback for Washington State, was the No. 2 pick in the 1998 draft behind Peyton Manning. But Leaf flamed out as quarterback for the San Diego Chargers, gaining a reputation as one of the biggest busts in NFL history
Last year, Leaf had surgery to remove a benign tumor from his brain stem and later underwent additional radiation treatments.
On March 21, Leaf told an Associated Press reporter in an email exchange that he had struggled through treatments and had an MRI scheduled for the end of the month, but "I'm doing/feeling much better and am excited for the rest of 2012."
