Adam Joseph Herrman, born Irvin Sylvester Groeninger III, was 11 years old when he disappeared from his family's mobile home at Pine Ridge Estates in Towanda, Kansas, in the spring of 1999. His adoptive parents, Doug and Valerie Herrman, would later claim he ran away after Valerie spanked him with a belt, and they never reported him missing. Nobody outside the family knew Adam was gone at all until late 2008, nearly a decade later, when his own adoptive sister discovered something that didn't add up and brought her concerns to the authorities herself.

A History of Reported Abuse

Adam's time in the Herrman household was marked by repeated, documented concerns from outside the family well before he disappeared. In November 1996, when Adam was still a young child, Derby Police removed him from the home for two days while investigating allegations of abuse, after he was found with bruises and abrasions. Doug and Valerie were cleared during that investigation, and Adam was returned to their care. In January 1998, Adam's school, Pleasantview Elementary, separately reported suspected abuse to Derby Police. The following month, the family relocated from Derby to Towanda, a move that placed them under a different jurisdiction's oversight entirely.

Accounts From Within the Family

Years later, relatives who had witnessed life inside the Herrman household came forward with detailed accounts of what Adam had reportedly endured. Justin Herrman, one of Valerie and Doug's own biological children, described his mother's behavior toward Adam as including punching him, pulling his hair, striking him with wooden spoons, and shoving him. Other family members alleged that Valerie refused to feed Adam at times, made him sleep in the bathtub without a pillow or blanket, and locked him in the bathroom for extended periods. Justin also said Adam was not allowed to play and was made to perform housework for extended stretches throughout the day. Justin, reflecting on his mother's behavior more broadly, described her as someone who could be a genuinely good person when she was not in a bad mood, but who became, in his words, a monster when she was.

A Story of Running Away

According to Doug and Valerie's account, Adam disappeared during the first week of May 1999, having run off after Valerie spanked him with a belt during a disciplinary incident. The couple maintained that Adam had a documented history of running away from home and characterized his final disappearance as simply another instance of the same pattern, one that, in their telling, did not seem to warrant involving law enforcement at all.

Nine Years of Institutional Silence

What makes Adam's case especially disturbing is not simply the alleged abuse he suffered, but the sheer length of time that passed with no outside party recognizing he was actually gone. Doug and Valerine continued receiving state assistance connected to Adam for years after his disappearance, and Kansas's Department of Social and Rehabilitation Services continued operating under the belief that Adam remained in the Herrman household, receiving no indication otherwise from the family itself.

A Sister's Discovery

That institutional blind spot finally cracked around Thanksgiving 2008, when Crystal Espinosa, one of the Herrmans' adoptive daughters, contacted the state agency in an effort to locate Adam herself. What she learned did not match what her parents had told the family for years. According to SRS records, Adam had supposedly remained with the Herrmans until 2005, directly contradicting the family's longstanding claim that he had returned to state custody back in 1999. Espinosa, alarmed by this discrepancy, shared her findings with SRS and voiced her own longstanding suspicions that Adam had been abused by her mother, finally setting in motion the investigation that should have begun nine years earlier.

An Investigation That Named Suspects

Once law enforcement became formally involved, both Doug and Valerie Herrman were named as suspects in Adam's disappearance. Sheriff Craig Murphy, overseeing the investigation, stated plainly in a 2009 interview that investigators were not certain what had happened to Adam, and that they were working the case as though it involved a death, without leaning definitively toward any specific theory of what actually occurred. Searches of properties connected to the family failed to turn up any human remains, and investigators noted at the time that murder charges remained a possibility even without ever recovering Adam's body, given the strength of circumstantial evidence surrounding his disappearance and the family's own conduct in the years that followed.

Convicted, But Only of Fraud

Despite being named suspects in Adam's disappearance, Doug and Valerie Herrman were never charged with harming him directly. They were, however, prosecuted for a separate crime connected to his case, fraudulently collecting more than 52,800 dollars in public assistance and tax deductions tied to Adam after he had already vanished. In 2011, the couple pleaded guilty to wrongfully receiving 15,488 dollars in subsidies between November 2003 and July 2005, money paid out under the continued assumption that Adam remained in their care. Doug received a nine month prison sentence, and Valerie received seven months, penalties that addressed the financial fraud itself while leaving the central question of Adam's actual fate formally unresolved.

A Hoax That Went Nowhere

In 2020, a claim circulated suggesting that a person online was, in fact, Adam Herrman, alive and reaching out after decades of silence. Investigators quickly examined and dismissed the claim as false, one more false lead in a case that has produced very few genuine ones over the years.

A Father's Death, A Mother Who Remains

Doug Herrman died of natural causes in July 2016 at the age of 61, having never faced charges connected directly to Adam's disappearance itself. Valerie was eventually released from prison after serving her sentence for the fraud conviction. Investigators have continued to state their belief that Valerie holds whatever information might finally explain what happened to Adam, information she has never disclosed.

A Fresh Dig in 2026

The case saw renewed activity in April 2026, when a tip prompted the Butler County Sheriff's Office to conduct an excavation near the mobile home park in Towanda where Adam once lived, focusing specifically on an area between a street and a privacy fence line in the old neighborhood. The search concluded within a few hours, with the sheriff confirming that nothing significant was found. The dig nonetheless represented the most concrete investigative activity connected to Adam's case in years, a reminder that Butler County investigators have never formally closed the file even as the trail has remained largely cold since the initial 2008 investigation.

Still Missing

More than 25 years after Adam Joseph Herrman disappeared from a Kansas mobile home park, following years of documented concern from teachers, neighbors, and eventually his own siblings, he has never been found, and no one has ever been charged in connection with whatever actually happened to him. He would have turned 39 this past June. Investigators continue to believe that Valerie Herrman remains the person most likely to hold the answer to where Adam actually is, an answer that, more than a quarter century later, she has still never provided.
