Kim Lene Williams, the wife of a former Texas justice of the peace, was charged with murder after confessing her involvement in the shooting deaths of the local district attorney, his wife and an assistant prosecutor. NBC'sGabe Gutierrez reports.

The wife of a jailed former justice of the peace in the Texas county where a district attorney and his wife were found dead in their home in March has been arrested and charged with capital murder.

Michael and Cynthia McLelland were found shot to death in their home March 30. Michael McLelland's deputy, Assistant District Attorney Mark Hasse, was killed in a separate shooting Jan. 31. Kim Lene Williams has been charged with capital murder in connection with all three deaths, Kaufman County sheriff's Lt. Justin Lewis said Wednesday afternoon.

Williams was admitted to the Kaufman County jail just before 3 a.m. local time Wednesday. She was held on a $10 million bond.

She confessed to her alleged involvement in the three killings in an interview with investigators on Tuesday, according to an arrest warrant affidavit the sheriff's office released Wednesday. She said her husband pulled the trigger, according to police.

"Kim Williams described in detail her role along with that of her husband, Eric Williams whom she reported to have shot to death Mark Hasse on January 31, 2013 and Michael and Cynthia McLelland on March 30, 2013,"according to the affidavit. "During the interview, the defendant gave details of both offenses which had not been made public."

Eric Williams remained in the Kaufman County jail after having been booked Saturday. He was being held on $3 million bond on a charge of making a terroristic threat and two charges of insufficient bond.

A probable cause affidavit, filed Friday in Kaufman County, alleged that a "terroristic threat was received via electronic communication" on March 31 by investigators looking into the McLellands' deaths.

"The threat implied unless law enforcement responded to the demands of the writer, another attack would occur," according to the affidavit.

A search for who sent the threat led investigators to the home of Eric Williams in Kaufman, where a search warrant was executed Friday.

"During the investigation, it was learned that the author of the electronic communication possessed unique identifiers to send the electronic communication," according to the affidavit. After a search of the house, "it was learned that the defendant had utilized these unique identifiers to send the threat" from his computer.

The search warrant affidavits for Williams' home were sealed and had not been released, Lewis told NBC 5 of Dallas.

Eric Williams was convicted of theft last year, a case in which he was prosecuted by McLelland and Hasse. Williams lost his position as a justice of the peace and had his law license suspended because of the conviction.

Investigators working on the deaths of the McLellands and Hasse found that both men "believed that Eric Williams blamed them for his removal from office" and "regularly carried handguns after the Eric Williams jury trial because they believed Eric Williams to be a threat to their personal safety," according to the affidavit released on Wednesday,

In an interview earlier this month with NBC 5, Williams denied having anything to do with the McLellands' deaths and said he didn't own a gun.

"If I was in their shoes, I would want to talk to me," he said at the time. "In the investigators' mind, they want to check with me to do their process of elimination."

An attorney for Williams said in a statement Friday that his client "has cooperated with law enforcement and vigorously denies any and all allegations."
