A 6-year-old boy went missing in 2011. On Wednesday, a teen identified himself to police as the missing child and told them he'd escaped a years-long captivity, according to a Sharonville police report.

On Thursday, FBI said DNA tests show that the person is not Timmothy Pitzen.

The teen was found by authorities in Newport, Kentucky.

Timmothy Pitzen of Aurora, Illinois, a suburb of Chicago, would be 14 years old today.

On Wednesday, the teen told police he'd escaped two male captors, one with a spider-web tattoo and the other with a snake tattoo, after they held him for nearly eight years.

He said he ran across a bridge into Kentucky as he fled his captors.

When did Timmothy Pitzen disappear?

Timmothy disappeared on May 12, 2011, according to the National Center for Missing & Exploited Children.

He was last seen at a water park in Wisconsin Dells, Wisconsin, according to the national organization that provides a database of missing children.

Mother Amy Fry-Pitzen found dead

His mother, Amy Fry-Pitzen, pulled Timmothy from his kindergarten class for a family emergency one day before the disappearance, according to a Chicago-based CBS affiliate. But no family emergency existed, and Fry-Pitzen accompanied her son on a trip to the Wisconsin water park and a zoo in Brookfield, Illinois, a suburb of Chicago.

His mother was later found dead in a Rockford, Illinois, hotel.

A note left behind stated Timmothy would never be found, but that he was safe and being cared for by a loved one, according to CBS Chicago.

Aurora Police Detective Lee Catavu told the outlet that there isn't "a single person in her life that believes Amy Pitzen has hurt that child."

The Aurora Beacon-News reported that Amy Fry-Pitzen struggled with depression and an "unhappy marriage" before taking her own life.

Timmothy's grandmother, Laura Pitzen, told The Beacon-News she believed, especially because Timmothy was growing older, that he'd one day be found.

"I feel it's not long, when he will be showing up," she said.

Father Jim Pitzen shares memories

Timmothy Pitzen's father, Jim Pitzen, shared memories of his son with mystateline.com in 2017.

Timmothy was a kindergarten student at Greenman Elementary School in Aurora, and Pitzen recalled the last time he saw his son, running toward a teacher before school.

Timmothy had hopped out of his father's Jeep and told his dad he loved him.

Cheryl Broach, Timmothy's teacher, told mystateline.com that she suspected something may have been amiss when Timmothy's mother didn't give her forewarning that she'd be pulling Timmothy from school.

"He walked down with his backpack on and he turned at the clock and waved, 'See you tomorrow.' I said, 'See you, Timmothy,' and he walked (away) and I would never see him again," Broach said.

Pitzen said Amy Fry-Pitzen adored her son, and that he was the "one person she would never do anything to."

"It's terrifying, not knowing where he's at," Pitzen said in 2017. "I keep hoping everyday that he comes home."
