According to Fox News he might be:

RENO, Nev. — A pair of women’s underwear found with the body of a college student who had been kidnapped and strangled may have been left behind to taunt authorities searching for a serial rapist, police said Tuesday.

The underwear contained the DNA of two people — the same man who committed at least two sexually motivated crimes against other young college women in the area in the past four months, and an unknown woman, police said.

“Our belief is the suspect in this case left these panties there either to taunt the police, to taunt the community, or somehow didn’t realize he had them and dropped them in that regard,” Chief Michael Poehlman told KKOH Radio.

The black thong underwear, emblazoned with the head of the cartoon character the Pink Panther, found with the body Friday did not belong to 19-year-old strangling victim Brianna Denison, police said.

Investigators are trying to determine whether the unknown DNA belonged to another woman who might have been assaulted.

Denison’s killer is feared to be a serial rapist. Check out Gretawire which has a nice round up and the most unseemly display of amateur sleuthing in the comments section you’ll find this side of a Black Dahlia convention.

Let’s just hope authorities can catch this animal soon.
