KAUFMAN, Texas -

The former justice of the peace in Kaufman County was charged with making a "terroristic threat," authorities said Saturday.

Eric Williams is in custody and scheduled to go in front of a judge Saturday morning, where bond will be set, a Kaufman County Jail spokesperson said.

Federal and local authorities had searched Williams' home on Friday as part of an investigation into the deaths of District Attorney Mike McLelland and his wife, Cynthia, whose bodies were found March 30 in their home. In late January, assistant DA Mark Hasse was fatally shot as he was leaving work in Kaufman, about 30 miles southeast of Dallas.

Williams hasn't been named a suspect in any of the deaths.

The district attorney's office prosecuted and convicted Williams last year for theft. He lost his justice of the peace position as a result.

Spokesmen for the FBI and the Kaufman County Sheriff's Office confirmed Friday they were executing a search warrant but declined to provide details. The warrant's underlying affidavit has been ordered sealed by a judge, said sheriff's Lt. Justin Lewis.

A listed phone number for Williams went unanswered Friday afternoon. But his attorney, David Sergi, released a statement Friday saying his client "has cooperated with law enforcement and vigorously denies any and all allegations."

"He wishes simply to get on with his life and hopes that the perpetrators are brought to justice," Sergi said.

Authorities have released little information about the case except to say they continue to follow leads, including possible ties to a white supremacist gang.

One month before Hasse's death, the Texas Department of Public Safety issued a warning to authorities statewide that the Aryan Brotherhood of Texas could retaliate for an October indictment that targeted some of its leaders. McLelland's office was involved in that investigation.
