"I saw a glimpse of him," said Cynthia Medina, a victim.
But a glimpse is all Medina needed.
"I felt a little power knowing that he could see us and we're the reason why he's still in there," said Medina.
Twenty-five years-ago, Medina and Mary Taylor were raped by Quarles.
Quarles was accused of attacking more than a dozen women. The sexual assaults were carried out as the victims' husbands or roommates were forced to watch.
He was sentenced to 50 years, but eligible for release after only 25, a now extinct state law that neither victim knew about.
"When I found out he was to be released, I fell apart," said Medina.
Medina did some digging and found out Quarles was to be released next week.
"He was going to slip through the cracks. He was just going to get out and be...somebody's neighbor," said Medina.
Together, the two sought out power attorney Gloria Allred. The district attorney, who apparently did not know of the possible release, is now seeking to keep him locked up.
"On the 19th, a judge will hear from two of the psychologists in this case that found that he does qualify under the sexually violent predator law," said Deputy District Attorney Wendy Patrick.
The civil case could have the 51-year-old committed for an extended sentence.
"I'm going to spend the rest of my life, or at least the rest of the time that he's alive in my life, worrying about this person," said Taylor.
And while a legal loophole was something his victims hadn't thought would be possible, they have been living with the memories all this time.
"It never goes away," said Medina.
