UPDATE 4/15: The Kaufman County Sheriff's Office released the arrest warrant for the terroristic threat charge against Eric Williams. It confirms an electronic communication was received by law enforcement officials investigating the McLelland murders that implied unless law enforcement responded to the demands of the writer, another attack would occur.
The author of that communication possessed unique identifiers to send the communication. During the search of Eric Williams' residence on April 12, investigators learned Williams used those identifiers to send the threat from his personal computer, according to the warrant.
On March 31, the day after Kaufman County District Attorney Mike McLelland and his wife were found dead in their Forney home, someone sent an anonymous e-mail threatening additional attacks, sources tell News 8.
That e-mail was traced back to former Justice of the Peace Eric Williams, according to those sources.
Williams is the main suspect in the murder case, sources say. He is currently jailed on unrelated charges and being held on $3 million bond.
News 8 has learned that 20 weapons were recovered from a unit at a Seagoville self-storage locker in connection with the unsolved Kaufman County murders. Sources said the locker had been rented on behalf of Eric Williams.
A source tells News 8 federal investigators are conducting ballistics tests on the weapons, which are similar to those used to kill Kaufman County prosecutor Mark Hasse on January 31 and District Attorney Mike McLelland and his wife Cynthia, who were found dead at their home on March 30.
Sources said investigators also seized a Ford Crown Victoria sedan from the storage facility that was allegedly purchased by Williams back in February under a false name.
Sources said they have surveillance video of that vehicle driving into and out of the McLellands' neighborhood on the day they were slain.
Sources said law enforcement officials obtained enough probable cause to search Williams' home and other properties after placing Williams under surveillance and by getting subpoenas in this case.
Williams was convicted last year for stealing three county-owned computers. Mark Hasse and Mike McLelland prosecuted him.
Williams also had his license to practice law suspended following his conviction.
He and his attorney, David Sergi, have vigorously denied any connection to the murders of the McLellands and Hasse. Sergi has not been available for comment since Williams was arrested.
Williams remains in the Kaufman County Jail on a $3 million bond after being arrested at his home early Saturday morning for allegedly making terroristic threats.
