Was there any evidence that Ted Bundy was bisexual?

I was actually looking up his bio today (not wiki), and there were no indications he was bi-sexual. There's a rumor that he was also a necrophiliac and kept ten severed heads in his apartment. I found no evidence of this either.

No. He never said he's bisexual. Although some experts or people who knew Ted Bundy suggest that he may have had homosexual tendencies.
