Sheriff's deputies in Genesee County say they've never seen anything sicker.

They say this man, Kevin Traver Odette, has committed so many sexual crimes against children that they don't even know where to start.

"Our investigation revealed Kevin Odette first molested two boys he was babysitting for when he was 10 years old," says Genesee County Sheriff Robert Pickell.

What Odette faces now, however, is life in prison after being charged with sexually abusing five nieces and nephews, as young as 7 years old, and exploiting them in homemade child pornography.

Sheriff Pickell says the amount of child porn in Odette's Vienna Township home was repulsive.

"We recovered 75 VHS tapes, over 200 DVDs, two computers, several digital cameras, a sexually explicit diary dating back to 1996," he lists, citing all were full of porn, much of it depicting him in sex acts with young children.

"My investigators, who are seasoned investigators, told me the videos are the most graphic they've ever seen," Pickell says.

Odette may be charged with molesting those five children, but authorities believe he's exploited and abused dozens more.

"Based on our preliminary investigation, it's possible Kevin Odette may have abused up to 70 juveniles," he says.

That might include people in Lansing.

Odette told police he molested two former classmates at Waverly High School in the 1990s.

"We suspect there'll be a considerable amount of people we'll hear from in Lansing," Pickell says.

Police say Odette has ruined children's lives, but they'll do all they can to make sure he doesn't get that chance again.
