Lynsi Snyder, the 34-year-old billionaire heiress and president of the In-N-Out burger chain, is frequently described as "reclusive," "private," even "mysterious." But in a new, nearly 10-minute video interview with I Am Second, Snyder gets surprisingly candid about her past. Snyder, granddaughter of the chain's founders, opens up about how she spiraled after her father died of a prescription-drug overdose in 1999. She discusses her own drug and alcohol abuse, failed marriages, and how she feels religious faith ultimately saved her, Business Insider reports. Snyder inherited half of In-N-Out's shares when she turned 30, and will get the other half in May when she turns 35. More on her background here. (More Lynsi Torres stories.)
