Here is an old article that says Mr. Seacat was arrested Friday, and the article was originally published May 13th, 2011. May 13, 2011 was a Friday.
"The charges, filed Friday by Kansas Attorney General Derek Schmidt, allege 35-year-old Brett Seacat killed his wife, Vashti Seacat, 34, and endangered their two young sons in setting the fire at their Kingman home."
