A third woman, Jasmine Miller, 26, was also attacked, but survived to tell officers what happened during the attack. Walker, 23, is a relative of the women.The chief said toxicology tests will establish what drugs were in Walker’s system at the time of the attacks, and it’s possible methamphetamine was involved.
