A freeze mob was held Saturday afternoon.
Participants stood motionless to protest the possible parole of one of the men convicted of killing Paula Bohovesky.
The 16-year-old Pearl River High School student was raped and murdered in 1980.
51-year-old Robert McCain will appear before a parole board later this month.
"I have two nightmares. One that Paula would be forgotten and we'd lose her past as well as her future. And the other is that her killers would get out and they would do it again," Paula's mother Lois Bohevski said.
A second man convicted in Bohovesky's murder was denied parole in May.
