KAUFMAN (CBSDFW.COM) – One day after Kaufman County District Attorney Mike McLelland and his wife Cynthia were found murdered, newly released court documents say former Kaufman County Justice of the Peace Eric Williams sent a threatening email to an unspecified official.

Documents say Williams’ threat implied that unless law enforcement responded to his demands, another attack would occur.

The documents don’t specify Williams’ alleged demands, but indicate that the threat led investigators to search Williams’ and his in-laws’ houses in Kaufman Friday afternoon.

Documents say Willliams sent the threat from his personal computer.

On Monday, Kaufman County Commissioner’s Court Judge Bruce Wood says progress is being made in the investigation, and that Williams was first mentioned as a suspect after assistant District Attorney Mark Hasse was murdered January 31st.

Sources tell CBS-11’s J.D. Miles that Williams will likely be charged with capital murder in the deaths of Hasse, and District Attorney Mike McLelland, and wife Cynthia, who were found murdered in their home March 30th.

Judge Wood says investigators are now looking to see if someone else was involved with Williams.

Williams has been in jail on a $3 million bond since early Saturday morning on a charge of making a terroristic threat and two charges of insufficient bond.

One of his neighbors, Richard Mohundro, watched as law enforcement officers emptied Williams’ house.

He says, “With the amount of personal belongings taken out of the house, I knew they had a big problem. The amount of manpower executing that, boy, they didn’t leav any stone unturned.”

On Saturday, investigators executed a search warrant at a Seagoville storage facility, where they pulled out a white Ford Crown Victoria.

Sources say it’s the same type of car spotted near the McLelland’s home on the night of their murders.

Sources tell us the storage unit was rented to Williams.

In addition to the car, sources say investigators found 20 weapons in the storage facility, and are in the process of conducting ballistics tests.
While Williams hasn’t been charged with the three murders, Kaufman residents are expressing a sense of relief after his arrest.

Susan Shannon says, “It is nice to know they have narrowed it down, there’s some very strong evidence and there may be some closure to this.”
Documents show authorities seized Williams’ cell-phone when they arrested him last weekend.

Sources say Williams’ lawyer David Sergei quit.

On Monday afternoon, Sergei’s office said he would have no comment and won’t return phone calls.
