He wasn't diagnosed with Asperger's either.
Most (if not all) of the Asperger's diagnoses in these situations have been done post-mortem. That is not a valid method of diagnosis.
the article I read said he had been diagnosed as Aspergers. Was the attorney wrong?
found it:

“Earlier, Peter Rodger’s lawyer, Alan Shifman, said.... Mr Rodger’s son had been “diagnosed at an earlier age of being a highly functional Asperger Syndrome child”, had trouble making friends and had been receiving professional help.”
