Parents were in shock Wednesday evening after they learned their children's taekwondo teacher was charged with raping a 12-year-old girl inside the studio in Queens.

Many parents showed up at Hugo's Taekwondo on Skillman Avenue in Woodside with their children only to find the studio closed. None of them had heard a longtime instructor with Hugo's was arrested on charges of first-degree rape and endangering the welfare of a child.

According to the Queens district attorney's office, 36-year-old Hector Quinchi of Woodside allegedly had sexual contact and intercourse with a 12-year-old girl who was enrolled at the taekwondo studio where he worked as an instructor.

Investigators said they believed the sexual contact occurred multiple times between August 15 and October 5, when Quinchi allegedly had sex with the preteen.

According to the criminal complaint, Quinchi confessed to the allegations.

Most parents NY1 spoke to said they knew Quinchi and were shocked by the news.

"Oh yeah, he's a really good instructor. I'm surprised with that I'm hearing so, you know, innocent until proven guilty. I think we should hear more about it. Shocking, I guess," one parent said.

Whether guilty or not, the owner of Hugo's said Quinchi will not return to work. Victor Armijos said he has been serving the neighborhood for 20 years and must maintain his stellar reputation with the families who entrust him with their children.

He said he was shocked because Quinchi was a former student himself and was always professional. But now he says that trust is broken and his heart goes out to the girl.

"I feel very bad for her family because everyone in martial arts is like a family," Armijos said. "He is very good. He had good potential teaching children and everything, and now with what happened I don't know."

Quinchi was arraigned in Queens Criminal Court on $100,000 bail. He faces up to 25 years in prison if convicted. His next court date is set for November 8.

Investigators urged other parents who suspect their child was victimized to call the NYPD Child Abuse Squad at 718-261-2737.
