(CBS) CBS News has learned that Mark Hasse, the Texas prosecutor gunned down outside the Kaufman County courthouse Thursday, was concerned about his safety in recent weeks.
Hasse told a longtime friend on Jan. 23 that he was being threatened. The friend said Hasse was carrying a gun everywhere he went and changed his exit route from work each day.
Hasse did not know who was behind the threats. He did not discuss the nature of them or how he received them..
Nearly $65,000 is now being offered for information in the murder, CBS DFW reports.
Authorities said no arrests have been made in the case. The Dallas County District Attorney's Office pledged $30,000 for information leading to an arrest and conviction of the shooting suspects, bolstering other reward money of roughly $35,000, according to CBS DFW.
District Attorney Craig Watkins told the station that the money came from assets seized in criminal cases.
"He is in a fraternity of prosecutors, so from Dallas County's perspective, we're going to do everything we can to bring those individuals to justice," Watkins said.
