Child Claiming to be Timmothy Pitzen is NOT the Missing Teen

3:31 PM PT -- Timmothy's Aunt and Grandmother have just spoken out, thanking law enforcement and promising that they will never stop looking for Timmothy.

They also asked everyone to join them in praying for Rini, stating, "We hope our tragedy will help to shed some light on the horrific problems of suicide and missing children in our country."

2:05 PM PT -- The story just keeps getting more bizarre ... the kid claiming to be Timmothy isn't a kid at all! Cops say he's a 23-year-old MAN named Brian Michael Rini.

1:48 PM PT -- According to The FBI, DNA testing has revealed the 14-year-old claiming to be Timmothy is NOT the missing child. A statement reads, "A local investigation continues into this person's true identity."

Timmothy Pitzen -- a 6-year-old child who famously went missing in 2011 and was featured on "Live PD" -- has allegedly been found in Ohio after escaping his captors.

The story's pretty wild. A teenager discovered by locals in north Kentucky Wednesday morning claimed to be Timmothy and said he'd just escaped his 2 kidnappers. He reportedly said they'd been holding him for 7 years. The locals then called 911.

Cops went on the hunt, and eventually found the boy in Sharonville, OH ... just outside of Cincinnati. He claims he's 14-years-old now, and managed to escape from a Red Roof Inn ... although he's unsure where the motel was. He describes his kidnappers as white men covered in tattoos on their necks and arms who look like bodybuilders.

It's unclear if the teen, who's now in police custody is, in fact, Timmothy. A DNA test to confirm his identity is reportedly underway and should take about 24 hours.

Timmothy initially disappeared after his mother took him out of school one day for a 3-day vacation, but she ended up being found dead a few days later at an Illinois hotel. A note was found near her body, saying Timmothy was safe with people who'd care for him.

The story was heavily covered at the time, and even featured last year on the popular A&E show, "Live PD." The show produced a visual rendering of what Timmothy should look like now.
