How does lord voldemort's parents die?

Lord Voldemort's parents, Tom Riddle Sr. and Merope Gaunt, die under tragic circumstances. Merope, who was a descendant of Salazar Slytherin, used a love potion to seduce Tom Riddle Sr., but after he abandoned her, she gave birth to Voldemort and died shortly after from despair. Riddle Sr. was later murdered by Voldemort himself when he sought to eliminate any ties to his past, making his death a direct result of his son's actions.
