KAUFMAN, Texas (AP) — The estranged wife of a former justice of the peace in North Texas is expected to plead guilty to murder in connection with the 2013 slayings of a district attorney, his wife and a top prosecutor.

Kim Williams is charged with three counts of capital murder, but it's unclear if she will plead guilty to all three indictments Tuesday.

Prosecutor Toby Shook says a tentative plea deal has been reached but declined to provide specifics until the agreement is signed.

Defense attorney Paul Johnson declined to comment.

Williams' husband, Eric Williams, was sentenced to death earlier this month for killing Cynthia McLelland, wife of Kaufman County District Attorney Mike McLelland. Eric Williams has been charged, but not tried, in the deaths of Mike McLelland and prosecutor Mark Hasse.
