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.He was placed on the FBI's Top Ten Most Wanted list. The same year, two children at the camp saw the FBI's Wanted poster and told the camp's staff about it.
They reported Alcala to the authorities, leading to him being extradited to California.
Because Shapiro's family had moved to Mexico and wouldn't let their daughter testify, Alcala got off with a guilty plead for a lesser assault charge.
When the FBI connected him to his old alias, they questioned him.
He confessed to knowing Hover, but denied committing the murder.
In 2003, while a third trial of Alcala was being planned, his DNA, which had been sampled during his time in prison, connected him to two other victims.
In 2010, Alcala was tried for a total of five murders: Samsoe, Jill Barcomb, Georgia Wixted, Charlotte Lamb, and Jill Parenteau.
In spite of what he had done, he was only found guilty of giving marijuana to a minor and violating his parole and was released after two more years of indeterminate sentencing.
In 1977, Alcala got permission from his parole officer to visit relatives in New York City.
Criminal profiler Pat Brown later suggested that this rejection angered Alcala further since he afterwards killed at least three more women within two years.
His last known victim was 12-year-old Robin Samsoe, who was abducted on her way to ballet class in 1979 in Huntington Beach and her decomposing body found in the Sierra Madres twelve days later.
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.
