(Seattle, WA)  --  Seattle Mayor Ed Murray says the name of the man who's accusing Murray of sexual abuse is "not familiar" to him.  Delvonn Heckard has elected to reveal his identity, about two weeks after he filed a lawsuit that claims he was a teenager when he was abused by Murray and was paid money by the defendant for sex.  Murray tells KOMO-TV he didn't have sex with Heckard or any other minor and has never paid anyone for sex.  Murray says he's sure the accusations are politically motivated.
