What are you basing this on?
In one sentence you're suggesting there is little factual information and in the next your naming suspects/organizations.
Sound like pure speculation to me.
Last month Kaufman County Assistant District Attorney Mark Hasse was gunned down outside the local courthouse by two men in tactical gear who remain at large, and authorities fear the murders may be connected to a retaliatory plot by Mexican cartels.
The drug cartels freelance their retail distribution and enforcement work to local street and prison gangs across the United States, and have recently been targeting both Mexican and U.S. law enforcement officials for assassination.
In the past the Kaufman District Attorney’s Office assisted in a federal investigation targeting the Aryan Brotherhood of Texas which allegedly is a methamphetamine distributor for the Gulf cartel as reported by Dave Gibson for the Examiner.
Assistant DA Hasse was assassinated on 1/31/13 in broad daylight in downtown Kaufman on the steps of the courthouse. Now his boss has been killed in his home. We may reasonably infer that a, the killers are fearless and b, they are big on making examples and sending messages.
And though the Sheriff's Dept. is tight-lipped about last night's killings some information is out there. Some is anecdotal, a Sheriff's I know told me that they were leaning towards the AB killing Hasse in revenge for his actions towards them.
Some you can glean from the internet:
