The videos were allegedly made in Piscataway in September 2014.
The Retro Fitness of Piscataway, on Kingsbridge Road. PISCATAWAY - There are 14 people who were surreptitiously videotaped by a Bound Brook man two years ago and the victims still don't know about it.
The man charged with spying on several men at various unidentified locations, Javier Tavira-Flores, 25, faces multiple charges of invasion of privacy.
The incidents happened in Piscataway in September 2014, in which Tavira-Flores allegedly filmed or photographed several unnamed victims without their knowledge and while their intimate parts were exposed, according to a previous report citing court documents.
At least one incident allegedly took place at the Retro Fitness of Piscataway, the report said.
"This was a situation where Mr. Tavira-Flores basically waited in a restroom for what I can tell for people to walk in and out ... and he was videotaping them during a particularly personal moment so to speak," said Middlesex County Assistant Prosecutor Joseph Sermon on a recently obtained recording of a pretrial intervention hearing last month.
Authorities have identified three of the 17 victims allegedly filmed by Tavira-Flores, officials said. The remaining 14 have not been identified.
"Frankly, the state has to speak for 14 unidentified victims here," Sermon said during the hearing. "People out there in the public that were victimized, frankly that don't even know they've been victimized at this point."
He added, "We're not going to publicize these videos obviously and say 'Oh, hey does anybody out there know one of these individuals, to some extent we may never find out who those other victims are."
Somerset County-based attorney Francine Gargano, who is representing one of the alleged victims, said last week that she was aware authorities had not identified 14 other victims.
Tavira-Flores' attorney, Jonathan Petty, said during the hearing that his client's motivation "was probably the culmination of another failed, yet secretive homosexual relationship that Mr. Tavira-Flores had that ended."
He added, "Mr. Tavira-Flores had no one in the world that he could discuss that with because he has been rejected by his own family, and for a two-week, give or take, stretch judge, he acted out for all of the crimes that are alleged in this indictment."
Superior Court Judge Diane Pincus ultimately rejected Tavira-Flores' request for PTI, according to Petty.
It remains unclear what authorities plan to do about the alleged remaining unidentified victims.
Sermon was reached by telephone but declined to comment.
The spokesman for the county prosecutor's office, James O'Neill, could not be reached for comment.
A call to Tavira-Flores' attorney, Jonathan Petty, was not returned.
Tavira-Flores also allegedly operated a photography business.
