"Perez was later the subject of an Internal Affairs Bureau investigation and was caught peeping into apartment windows and in the act of having sex with a prostitute, according to court filings. He resigned shortly afterward. He had been off-duty during all the Pattern #1/91 incidents."

I'm not sure but that NYPD cop, Perez, per the Long Island Press, does seem like a good candidate. Let's say he kills the girls who fought back or maybe even those that bit or scratched him...I'm thinking of "Peaches"...the time line fits. He was said in that article to be 30 in 1991 so that puts him at 50 today...maybe a little too old, now, to be dismembering people.
If I read the article correctly it appears that Perez was initially reassigned to the "Evidence Room" but later, after being caught in the act of peeping, he "resigned." So, presumably by the time Peaches is murdered in 1997, this guy has been put out to pasture and was by then a FORMER NYPD officer. He probably held a good grudge against his former co-workers. It is possible that this would fit into a SK profile in that he may have escalated from his rape MO to other more vicious acts and by 1997 began killing his victims...initially feeling like he had to eliminate any identifying markers on the victims bodies. Another interesting fact about the "Silver Gun Rapist" is that he often attacked by twos; meaning two victims at a time. That shows that he was very confident in his ability to control his victims.
