Perry offers $100,000 reward for information on prosecutors' killers

McLelland's office had been part of a multi-agency investigation of the Aryan Brotherhood of Texas. McLelland had also vowed to find the killers of Kaufman County Assistant District Attorney Mark Hasse, who had been murdered near the courthouse where he worked a few months earlier.

"Today I'm announcing that my office is offering a cash reward of up to $100,000 for information leading to the capture and indictment of those responsible for the deaths of Mr. and Mrs. McLelland as well as Mr. Hasse," Perry said. "As you know, Kaufman Country Crime Stoppers is already offering a $100,000 reward for information leading to the arrest and indictment of those responsible for Mr Hasse's death."

Perry said he expected the killers to be found and arrested.

"It is our hope and our expectation that these rewards will help convince those who may be holding important information to come forward," Perry added. "Now regardless, the criminals responsible for these murders will be caught, they will be convicted, and they will pay the price for these horrific crimes."

A day earlier, Sen. John Cornyn (R-Texas) sent a letter to Attorney General Eric Holder asking the top Department of Justice official to allow federal court officials be allowed to carry firearms in court buildings.

Cornyn cited the deaths of the two Kaufman County prosecutors in his letter.

"Two state prosecutors have recently been murdered in Texas under suspicious circumstances possibly related to cases under their purview," Cornyn wrote. "Press reports indicate security measures covering some federal prosecutors have been increased, and I am concerned for the safety of other prosecutors at both the federal and state levels."
