HUNTSVILLE, Texas (AP) — A Texas man has been executed 13 years to the day of a convenience store robbery in which he set a clerk on fire in a Dallas suburb. Matthew Lee Johnson received a lethal injection Tuesday evening at the state penitentiary in Huntsville. He was condemned for the May 20, 2012, attack on 76-year-old Nancy Harris, a great-grandmother who he splashed with lighter fluid before setting her on fire. Badly burned, she died days afterward. Johnson expressed remorse Tuesday evening and asked for forgiveness from relatives of the victim who watched the execution through a window. Elsewhere, an Indiana man was executed earlier Tuesday for the killing of a police officer.
