Rebecca Jayne Penix, 52, of Waco, Texas, died on September 13, 2015, after being shot multiple times in the head during a domestic incident at her home. The arrest affidavit says the shooting followed an argument in which her husband, Michael Hanley Penix, told investigators Rebecca woke him in the middle of the night and he shot her; bloodstain patterns indicated she was lying on her back when struck.

Rebecca was born September 27, 1962, in Dallas and worked in health care management. A member of the Church of Christ, she is survived by her daughter Mallory Davidson and son Mitch Davidson. Michael Penix was arrested in connection with the killing; he later pleaded guilty and was sentenced by a McLennan County jury to 99 years in prison in December 2016.

Rebecca’s daughter Mallory has spoken publicly about domestic violence and uses her mother’s story to raise awareness of isolation and mood changes as warning signs. If anyone knew Rebecca or witnessed events around that night, does anyone have information that could add context to what happened?
