ONTARIO COUNTY, N.Y. -- Victims of a Victor man who admitted to secretly taping dozens of teens and women in his business changing room say they are satisfied he is going to prison.

Dozens of people packed into the Ontario County courtroom on Monday to support each other and to find out the fate of Glen Siembor, 47. They breathed a sigh of relief as the judge sentenced him to five to 15 years in prison.

“I’m thinking that he deserves everything that he getting in prison. I’m happy he’s going to prison,” victim Abigail Hall said.

Like many of his victims, Hall said she regarded her basketball and soccer coach as a close, trusted friend. That was until she found out he had secretly taped her and her sister in his businesses changing room after asking her to try on undergarments.

“Our family has been through some tough times with this, and we’ll pull together and conquer through it,” Hall said.

In June, Siembor plead guilty to 33 counts of unlawful surveillance and one count of endangering the welfare of a child.

Not only do investigators say they found cameras in his Victor-based business Tri Running and Walking, some victims who spoke in court on Monday say they found out he had taped them showering in his home.

One victim said she considered him one of her closest friends and had tried on clothes when he convinced her to. When she found out what was going on, she said he cried and promised to go to counseling. She called him an “excellent manipulator” and said he was “playing me like a fool.”

Another victim said her family befriended him and he violated that trust by sneaking a camera into her bedroom. Now she said she can longer sleep in her own bed. They said they felt his sentencing was justified.

“I think it’s well deserved,” victim Brigid Lawler said. “It’s needed. I’m happy about it.”

District Attorney Michael Tantillo said he was also pleased with the sentence.

“The length of time this went on for almost 10 years, the profound psychological impact this had on so many people and then on top of that what was really troubling is was what he did with these videos afterwards, how he used them for his own sexual gratification and what I found most troubling was the fact that he did this as he was viewing images of little children,” Tantillo said.

Before his sentencing, Siembor said he accepts full responsiblity for his actions. He told his victims sorry several times and said his feelings of remorse were sincere.

Some, however, said they don't believe him.

“Not at all,” Hall said. “He’s not sorry, I don’t believe he’s sorry one bit. He did it for many years. If he was sorry he wouldn’t have done it.”

Siembor’s attorney, David Murante, feels his sentencing was too severe. He said Siembor was diagnosed with depression, ADHD and bipolar disorder which could have caused reckless behavior and believed he could be rehabilitated.

“I think that’s a harsh sentence, too harsh for the conduct he committed,” Murante said. “Not to say he shouldn’t have been punished, but the question is proportionality.”

Tantillo pointed out there are an estimated 15 more unidentified victims out there, but for the known victims this is some closure.

“Obviously there’s going to be some left open-ended questions and why he did it and everything, but there’s some closure to this,” Hall said.

The judge mandated Siembor must also register as a sex offender. There will be a proceeding later to determine his level.
