After 34 months, in 1974, he was released and kidnapped a 13-year-old girl named as "Julie J." in court records, forced her to smoke marijuana and kissed her.
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.
Shortly after arriving (coincidentally during the time that Son of Sam was active), he is believed to have killed Ellen Jane Hover, a 23-year-old socialite.
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.
The sentence was overturned twice, first in 1984 because the jury was told about his previous convictions before the trial and then again in 1986 on the grounds that a witness had been hypnotized.
While in prison, he published a book titled You, The Jury, in which he denied killing Samsoe and posited another suspect.
They reported Alcala to the authorities, leading to him being extradited to California.In 2010, Alcala was tried for a total of five murders: Samsoe, Jill Barcomb, Georgia Wixted, Charlotte Lamb, and Jill Parenteau.
