(KCEN) -- We have an update on the Texas prosecutor shot to death outside a courthouse.
Tonight a friend of the mans says he feared for his life.
A Dallas attorney and friend of Kaufman County Assistant DA Mark Hasse says he recently started carrying a gun to work.
He told her, "I've been threatened" but didn't know by whom.
According to Colleen Dunbar, "He said, 'I've been threatened.' I said, 'Who's threatening you.' he said, 'I don't know. He had his gun on him when he would leave the courthouse. He said, 'You know, Colleen, there are three exits to the courthouse. I go out a different exit every day now, and I have my gun drawn.'"
Investigators are looking into whether Hasse's killing was in retaliation for any of his former cases.
