WATCH Ex-Justice of Peace Probed in Texas DA Slayings

The guns that police found in the home of a former Kaufman County, Texas, justice of the peace will be compared to the ballistics in the slayings of two county prosecutors who were gunned down earlier this year, sources say.

Eric Williams, 46, of Kaufman, was booked into the Kaufman County Jail early Saturday morning for allegedly making a "terroristic threat" to residents via email. Police have not released the nature of the alleged threats. He is jail on a bond of $3 million.

Williams' attorney, David Sergi, did not return ABC News' request for a comment.

Williams has not been named a suspect in the deaths of the Kaufman County officials. His hands were tested earlier this month for gunshot residue in connection to the slayings. The test results were negative, officials said

The search of his home and storage facility comes after the fatal shooting of District Attorney Mike McLelland and his wife, Cynthia, whose bodies were found in their Forney, Texas, home March 30. Assistant District Attorney Mark Hasse was gunned down in January outside the county courthouse.

A number of weapons were removed from Williams' home and will be compared to ballistics in the killing of McLelland and his wife, as well as forensics in Hasse's slaying, the sources said.

Ballistics test should be complete early this week.

Police are also looking closely at a Ford Crown Victoria that is tied to Williams. It is similar to the one allegedly seen in the McLellands' neighborhood around the time of the killings.

The district attorney's office prosecuted and convicted Williams last year for two counts of felony theft, which resulted in his losing his justice of the peace position.

The slain prosecutors gave closing arguments before a jury convicted Williams last April. They questioned his character and suggested he was prone to threatening others. A former girlfriend testified before he was sentenced that he had shown her a gun and frightened her enough to call the police.

Hasse said at the trial, "He's an elected public servant who is just a flat-out thief and burglar and needs to be removed from office and convicted of being a thief and a burglar, [because] that's exactly what he is, with quality evidence of him doing it on video."

McLelland described the case as an example of "the fox watching the henhouse."

Williams received two years' probation, and in addition to losing his job, lost his law license.

Williams appealed his conviction. He is scheduled for a hearing May 22 in the Fifth District Court of Appeals in Dallas.
