Growing up, half sisters Glennette Rozelle and Jennifer Mack were used to hearing their parents fight.
At StoryCorps, the women remember the night that changed everything for their family.
It was Valentine's Day, 1977. Minnie Wallace and Virgil "Glenn" Wallace were raising four children outside Oklahoma City. Glennette, then 7, and 10-year-old Jennifer, who was Glenn's stepdaughter, were home on a night that took them decades to process.
