Prosecutors in Rock Springs, Wyo., said Tuesday that one of those victims was Christine Ruth Thornton, 28, of San Antonio.
They said Alcala met Thornton and killed her while on a road trip, then buried her on a ranch in Granger, Wyo.
By the time they arrived, Alcala had struck Shapiro with a steel rod and raped her.
When they knocked on the door, he escaped out the back and evaded arrest. In 1971, Alcala is believed to have raped and strangled Cornelia Crilley, a Trans World Airlines flight attendant, in her Manhattan apartment.
His father, Raoul Alcala Buquor, abandoned the family when he was young. In 1968, he graduated from the UCLA School of Fine Arts with a Bachelor of Fine Arts degree and later studied film under Roman Polanski (whose wife would later become a victim of the Manson Family) at the New York University under the name "John Berger".
When he was 12, he, his mother Anna Maria Gutierrez, and his sisters, Christine and Marie, had moved to suburban Los Angeles. In the summer, he worked as a counselor at a drama camp for children in New Hampshire.
Alcala's first known victim was an eight-year-old girl named Tali Shapiro, whom he abducted as she was on her way to school.
