A domestic dispute in Jackson, Mississippi, on the evening of Wednesday, January 29, 2014, ended in gunfire that killed 49-year-old Tyrone Liddell Sr. and his 74-year-old mother, Bertha Lee Liddell. The next morning both bodies were found: Tyrone Sr. in the front yard of the Voorhees Avenue home and Bertha inside the residence. Both had been shot multiple times; investigators reported a .40-caliber weapon was used, though the firearm had not been recovered at that time.

A neighbor outside the home said they heard the argument between Tyrone Sr. and his 20-year-old son, Tyrone Liddell Jr., the night of the shootings. With assistance from the younger man’s mother, officers located and arrested Tyrone Jr. in a vehicle in Jackson on Thursday night; he was charged with two counts of murder and held without bond as the sole suspect in the double homicide.

If anyone has information about the events on Voorhees Avenue that night or about the whereabouts of the weapon, please share what is known.
