Closed for a family emergency, that's what the sign says at the martial arts studio run by 42-year-old Robert Lintzenich, who is charged with five counts of first-degree criminal sexual conduct.
"It's shocking, shocking," says Ludmila Gess, who owns a business close by. "You think about and hear about these things everywhere else. You don't think that it can happen so close to where you are."
"It's kind of scary," echoes Nicole Colgan, whose nephew attended the suspect's classes. "You don't know who you can trust anymore. Just going there for Tai Kwon Do practice, helping them, really good with the kids, really friendly, so it's really shocking to me."
This picture from the studio's website identifies Lintzenich as "Mr. L," a certified Tae Kwon Do instructor with more than 20 years experience.
Livingston County Undersheriff Michael Murphy says authorities have identified two victims of sexual abuse, both close to him.
"One of the victims stated the abuse had been going on for at least 10 years," says Murphy.
Murphy says Lintzenich has no criminal record, but that complaints had been made against him in two other states.
"If those allegations are legitimate, then he needs to go away for a long time--there is no question about that," Murphy says.
Authorities are not aware of any other victims, but Murphy says concerned parents should err on the side of caution.
"Bottom line is it certainly wouldn't hurt to ask their children if there was any inappropriate activities or behavior that happened while they were at the studio," he says.
Lintzenich is currently being held at Livingston County Jail on $1,000,000 bond.
If convicted, he faces life in prison.
