(CNN) — Evidence found in a storage unit could hold clues in the murders of two Texas prosecutors.
On Saturday, authorities arrested former Kaufman County Justice of the Peace, Eric Williams, on an unrelated charge.
He is being held on a $3-million bond for allegedly making a "terroristic threat."
The Dallas Morning News reports authorities found several weapons inside a storage unit linked to Williams.
He has a history with law enforcement authorities, including the Kaufman County District Attorney's office.
Last year, Williams got probation for stealing computers from the county and he lost his job.
"Something has triggered that the judge in the cases from last year, where he was accused of burglary of a building and theft, and taking laptop computer, or monitors from the county courthouse, he was almost called an appeal bot. And somehow whatever the activity was, there were some alleged threats after e-mail made after the Mcclelland killings, the judge said we're going to revoke your bond and hold you in jail until we figure out what's going on. So, that's - so right now the judge decided that it was best for him to be off the street. But the charges are probably forthcoming," said Pete Schulte, Attorney, Kaufman Co., Texas
District Attorneys Mark Hasse and Mike Mclelland prosecuted Williams for the computer theft.
Hasse was gunned down in January near the county courthouse.
Mike Mclelland and his wife Cynthia were found shot to death in their home last month.
Williams has not been charged in either of the killings.
