Here we go.
The man charged in a multi-count child exploitation case in Shawnee County is now telling the court—through his attorney—that he didn’t have the mental capacity to commit the crime.
Not didn’t do it.
Not wrong guy.
Just… couldn’t form the intent.
The Filing
In a new court document filed April 29, defense attorney John W. Kerns formally notified the court that Joseph James Lake III intends to argue that, because of a mental disease or defect, he lacked the required mental state to commit the alleged crimes.
That’s legal language for:
“Even if it happened, he wasn’t mentally there.”
This is filed under Kansas statute K.S.A. 22-3219, which allows a defendant to raise what’s essentially a mental state defense.

Let’s Be Clear About What That Means
This is not a free pass.
This isn’t a magic wand where charges disappear because someone says “mental health.”
What it does is shift the fight:
- From what happened
- To what was going on in his head when it happened
And that’s a much harder thing to prove.
Is It a “Valid Excuse”?
Short answer: It’s a valid legal strategy. Not a guaranteed defense.
For this to actually work, the defense has to show:
- A recognized mental disease or defect, and
- That it prevented him from forming the specific intent required for the crime
That’s a high bar. Courts don’t just take someone’s word for it.
Expect:
- Psychological evaluations
- Expert witnesses
- A battle between doctors on both sides
And even then? Jurors tend to be skeptical—especially in cases involving allegations like this.
Why This Filing Matters
Because it changes the tone of the entire case.
Up until now, this was shaping up as a straight prosecution:
Multiple counts.
Digital evidence likely in play.
Trial set for July.
Now?
This becomes a credibility war:
- Experts vs. experts
- State vs. defense narratives
- Intent vs. incapacity
The Reality Check
Let’s not lose the thread here.
The charges themselves—multiple counts of sexual exploitation of a child—are among the most serious filed in this courthouse.
And filing this kind of defense doesn’t mean the case is weak.
It means the defense is looking for any viable path to create reasonable doubt.
What Happens Next
If this defense moves forward, the court may order:
- Mental health evaluations
- Competency hearings
- Additional pre-trial motions
And that July trial date?
Don’t be surprised if it moves.
Bottom Line
This isn’t a dismissal.
It’s not an acquittal.
It’s a pivot.
And now the question isn’t just “Did it happen?”
It’s:
“Could he legally be held responsible if it did?”
That’s where this case is headed next.
