In the killing of a Texas District Attorney and his wife Saturday -- and the death of the DA's deputy two months earlier -- suspicion seems to be focusing on a white supremacist gang. But authorities aren't ruling out drug cartels, local meth makers or even someone with a grudge.
In a press conference, Gov. Rick Perry said prosecutors have a dangerous job. "This, I think, is a clear concern to individuals who are in public life. Particularly those who deal with some very mean and vicious individuals. Whether they’re white supremacy groups or whether they’re the drug cartels that we have."
Last year, DA Mike McLelland's office helped bring down 34 alleged members of the Aryan Brotherhood of Texas.
In December, the state warned of possible revenge attacks. Assistant DA Mark Hasse was killed the next month. But he was not involved in that investigation.
