As the manhunt for the ex-L.A. cop wanted for the murder of three reaches its sixth day, authorities are exploring the possibility that he may have received outside help. The suspected associate, identified as “JY,” could have been essential in helping the fugitive flee to Mexico, where authorities now suspect he is hiding. The detailed explanation of his moves was released in court records Monday, according to an affidavit by Inspector U.S. Marshal Craig McClusky, who first suspected the possibility of an accomplice. The report sheds additional light on Dorner’s path, including his failed attempt to hijack a boat in San Diego, even after subduing the captain. Now offering a $1 million reward for the rogue ex-cop, prosecutors anticipating his capture have already filed murder and attempted-murder charges against him.
