Only supposition my part here: Wait, first, though, please clarify. How did the Hasse murder come off, or how were perceived threats disseminated to Hasse despite limited threat info availability? Or are your alluding to the murder of Kaufman DA, McClellan?
I was referring to Kaufman County District Attorney Mike McLelland and his wife. My understanding was they were armed at all times and always used the peep hole at home and were being very careful.
