What he says
My primary residence is in the 44th. I mean it's no secret that I own some property in another district. But, you know, my primary is in the 44th and I've registered with the Secretary of State, the Boone County clerk and I've got all my, you know, as far as all my paperwork is taken care of there to be a resident of the 44th.

He has never said when he moved in, how much time he spends there, or what he does with the larger house in the 47th.
What the water meter says
A screenshot posted in a comment on his own Facebook page, since removed, appeared to show the water account for the Buffalo Drive house over the summer of 2026. The committee has not been able to authenticate the document. If it is genuine, this is what it shows.

The EPA puts average household water use at about 82 gallons per person per day. Low usage does not settle where someone lives. Travel, a bad meter, or something else could explain it. But 282 gallons in a summer is not what an occupied home looks like, and he should explain it.
What the Constitution says
Article III, Section 4 requires a representative to have lived in the district for one year before Election Day. Section 13 says a representative who moves out of the district vacates the seat. Section 18 makes the House itself the judge of whether a member meets those requirements. Missouri courts look at where a person actually lives and intends to stay. Owning property, getting mail, or filing paperwork at an address does not by itself make it a residence.
He lives somewhere. The record does not make it clear where, and he has not cleared it up.
