"Are we talking about Jose Padilla, the guy arrested for plotting to detonate a dirty bomb in the U.S.? Or a different "John Doe #2" ?" At the time of his arrest, some remarked that Jose Padilla resembled the John Doe #2 sketch. So, I presume Rodney King was referring to that Jose Padilla.
For much more on the Jose Padilla angle:
http://www.whoisjohndoe2.com Lana Padilla is not Filipina. She's anglo, maiden name Walsh. Padilla is the surname of her third husband, Leonard Padilla.
In an interview with the Wall Street Journal (facilitated by yours truly), she said she was not aware of any relation to Jose Padilla (but she did think that he looked a lot like the JD2 sketch).
Nichols' second wife, Marife Torres, was a Filipina.
