On February 8, 1975, 24-year-old African American woman Betty Williams was brutally murdered in Fort Worth, Texas, by 26-year-old Kenneth Granviel, a convicted serial killer. Granviel lured Betty Williams to his apartment under the pretense of giving her a package of cigarettes. Once inside, he attacked her, turning her upside down to disorient her, then proceeded to rape and stab her multiple times. During the assault, another woman, 21-year-old Vera Hill, entered the apartment. Granviel stabbed her in the chest, stomach, and back until she collapsed. He then returned to the bedroom to continue his assault on Betty Williams, beating and stabbing her further. Although she was still alive, Granviel left the apartment, only to return later and find her attempting to stop her bleeding. He told her to stop, and she complied, ultimately succumbing to her injuries.
Following these murders, Granviel's violent spree continued. He visited a friend's house, where he raped the friend's mother and held other family members hostage. He then kidnapped one of the daughters, took her back to his apartment, and raped her. Granviel's actions led to his arrest and subsequent confession to multiple murders. He was convicted and sentenced to death, with his case highlighting the dangers posed by individuals with violent tendencies and the importance of thorough criminal investigations.
