KAUFMAN -- Kaufman County Assistant District Attorney Mark Hasse is being remembered as thorough, tough, and fair by those who were in the courtroom with him.
"Well, he has dealt with some of the worst people in our society and was a very aggressive prosecutor," said Kaufman County Judge Bruce Wood.
The reward for information that leads to a conviction in the case climbed to over $71,000 Friday.
He could be "in your face," said attorneys who knew Hasse, but he never crossed the line. For the same reason criminals might not have liked Mark Hasse, the rest of Kaufman County did.
"The thing I keep hearing over and over is how bright and intelligent he was," Wood said, "but also how fair he was to defendants as well."
Wood once testified in a case Hasse prosecuted. He remembers Hasse being confrontational, but professional. That was his reputation even in the 1980's, when he was an assistant DA in Dallas.
"I just know he was a very good prosecutor. One of the best," said former Kaufman County Judge Wayne Gent. "To be a good prosecutor, that comes with the territory -- you have to be aggressive."
Hasse was known to carry a gun and sources confirm he was armed when he was ambushed Thursday morning, walking from his car to the courthouse. Witnesses saw a gunman, possibly two, in all black, maybe even in tactical gear confront him, shoot him, and then take off.
Investigators are going over hundreds of cases Hasse has worked - even cases from years ago - expecting to uncover a link between his life profession and his death.
While Hasse has tried cases involving the Aryan Brotherhood, he had no open cases involving them. That group is a part of the investigation but detectives say it is not the sole focus, by any means.
