Butler County Sheriff: Man claiming to be Adam Herrman is not him

WICHITA, Kan. (KWCH) Update Monday, Feb. 24, 2020

A Wichita man took to social media over the weekend, claiming to be a Butler County boy missing since 1999. Investigators say it's all a hoax.

Butler County Sheriff Kelly Herzet was the original investigator on the case when Adam Herrman disappeared. He says he knows the case better than anyone and knows for a fact the man claiming to be Adam is lying.

"I received a phone call (Sunday) from my detective who is in charge of the Adam Herrman case now, and asked me if I had seen what was on social media. And I told him, 'no, I really don't follow social media,'" Herzet says.

That phone call led Herzet to the Twitter page using Adam Herrman's name, started by a Wichita man claiming to be the missing boy, not seen since he was about 10 years old, more than 20 years ago.

"Knowing as much about the case as I know about the case, I knew for sure it was not Adam Herrman,," Herzet says.

He says the man making the claim has caused a stir on social media, even prompting calls from Adam's family, but the man refuses to cooperate with the sheriff's office.

"It wasn't long after someone read this on Twitter. The family is calling me going, 'Is this Adam?' Herzet says. "And I'm telling them, not even knowing as much as I know about the case, 'no, this is not Adam."

Why the man who once worked for the Butler County Detention Center is making the claim, Herzet doesn't know. What he does know is that this man is not who he claims to be in the recent video he shared.

"The person claiming to be Adam Herrman is not Adam Herrman. I mean, that's the bottom line," Herzet says. "Social media can take that wherever they want to take that, and they can say whatever they want to say."

Herzet says he's spoken with the family claiming to be Adam Herrman and says they are trying to get him to take the Twitter account down and cooperate with investigators.

Herzet has also discussed the developments with prosecutors and at this time, there are no plans to file any charges.

Eyewitness News has received several messages concerning a newly created Twitter account that claims to be missing Adam Herrman.

Adam disappeared from the home of his adoptive parents, Doug and Valerie Herrman, back in 1999. He wasn't reported missing for 10 years.

In 2018, Valerie told Factfinder 12 investigator Michael Schwanke that she feared losing her other kids, so she never reported him missing.

The Butler County Sheriff's Office is aware of the Twitter account. They are investigating the claims.
