Texas executes man convicted of shooting estranged wife to death in 2005

John Gardner, 64, was pronounced dead at 6:36 p.m. at the state’s death chamber in Huntsville, the Texas Department of Criminal Justice said in a statement. Soon after they got married in 1999, Tammy Gardner began showing signs of physical abuse that included bruising, headaches, sleeplessness, anxiety and depression, prosecutors said. On Jan. 23, 2005, about a month after she filed for divorce, Tammy Gardner, 41, asked a co-worker to help her “disappear” so no one could track her.
