Authorities have not discussed a motive.
The slayings also called to mind the death of Colorado’s corrections director, Tom Clements, who was killed March 19 when he answered the doorbell at his home outside Colorado Springs. Two days later, Evan Spencer Ebel, a white supremacist and former Colorado inmate suspected of shooting Clements, died in a shootout about 100 miles from Kaufman. On Monday, judicial officials acknowledged Ebel was freed four years early because of a paperwork error.
In an Associated Press interview shortly after the Colorado killing, McLelland himself raised the possibility that Hasse was gunned down by a white supremacist gang.
After that attack, McLelland said, he carried a gun everywhere around town, even when walking his dog. He figured assassins were more likely to try to attack him outside. He said he had warned all his employees to be constantly on the alert.
