There's no motive in the case, which has rattled even seasoned veterans of the Los Angeles Police Department.
"There was no incident or dispute or clear motivation for this horrific attack. He did not know his victim. It defies explanation," LAPD Deputy Chief Kirk Albanese told the Los Angeles Times. "He is not of sound mind.... The motive is mental illness."
Authorities have not identified the woman, but Van Nuys residents told KTLA she was known as Flo Parker or Violet.
