Sedgwick County CPS Scandal: When Law Enforcement Fails Families
The people of Sedgwick County, Kansas, are now facing a troubling question: What happens when the very people entrusted to protect our children are the ones who compromise their safety?
Detective Shawn McMahon, a longtime officer with the Sedgwick County Sheriff’s Office, has been charged with two felony counts of Making a False Writing and one felony count of Interference with Law Enforcement. McMahon worked in some of the most sensitive and vital child protection units, including the Exploited and Missing Children’s Unit (EMCU) and later the Internet Crimes Against Children (ICAC) task force.
The allegations are serious. According to the Sedgwick County District Attorney, McMahon is accused of falsifying official reports and prematurely closing child abuse investigations between 2019 and 2024. An external investigation was launched in December 2024 when internal audits raised red flags about CPS-related cases that lacked critical follow-up.
Wichita Police’s ALERT team took over the investigation and found that multiple child protective services cases were marked as complete, despite no interviews, no medical exams, and in some instances, no investigation at all.
Let that sink in.
We’re not just talking about paperwork mistakes. We’re talking about the potential erasure of truth in cases that impact real families. And in a system already known to tear families apart more often than it protects them, the consequences are staggering.
Sedgwick County CPS Failure: Broken Trust, Broken Families
These criminal charges are not just about one detective. They are a flashing red warning about the fragility of trust in Sedgwick County Child Protective Services and law enforcement.
When families speak out about false CPS allegations, investigator bias, or children being removed without due process, they’re often dismissed. But what happens when law enforcement is caught faking the process entirely?
Here’s what we know nationally about the dangers of the foster care system:
Nearly 50% of youth who age out of foster care will experience homelessness within four years.
60–70% of children in human trafficking come from the child welfare system.
Children in foster care are twice as likely to suffer from PTSD as U.S. war veterans.
Fewer than 3% of aged-out youth earn a college degree.
One in four foster youth will be incarcerated within two years of aging out.
Counties receive $41,000 to nearly $200,000 per year in federal and state reimbursements for every child they place and keep in foster care.
These statistics reveal a troubling pattern: instead of supporting struggling families, CPS and the foster care system often dismantle them. And now, with allegations of false reporting and case manipulation within Sedgwick County CPS investigations, that harm has only deepened.
If the charges against Detective Shawn McMahon are true, children may have been taken from stable homes or left in dangerous situations—based not on facts, but on forged files.
Some families may have been wrongly shattered. Others may never know that their case was quietly sabotaged. Either way, this is more than misconduct—it’s systemic collapse.
The Felony Allegations Against Detective Shawn McMahon
All suspects are presumed innocent until proven guilty in a court of law. However, based on the complaint filed:
False Writing (2 counts): Detective McMahon allegedly recorded investigative actions that never occurred.
Interference with Law Enforcement (1 count): He is accused of hindering active investigations by fabricating or omitting key details.
These felony charges reflect not just ethical failure, but legal and constitutional violations—especially when they involve Sedgwick County families and vulnerable children.
Consequences and Next Steps in Sedgwick County
Detective McMahon is currently suspended without pay. The Sedgwick County Sheriff’s Office has launched an internal audit to review every CPS-related case he handled between 2019 and 2024.
He is expected to appear in Sedgwick County District Court the week of July 14, 2025.
Each felony charge carries potential prison time. But the greater cost—the lives impacted, the trust broken, the children displaced—cannot be measured in years or months.

How many other CPS workers, investigators, or county officials are making decisions that devastate families without just cause?
