Makena White, the 28-year-old girlfriend of PGA Tour golfer Jake Knapp, died suddenly earlier this week. The exact cause of her death has not been publicly disclosed by her family or close associates. Fans and friends noted her past health issues with tachycardia, a condition involving an abnormally fast heart rate, which she had mentioned in social media posts earlier in 2025. However, it remains unclear if this was related to her passing. Tributes have described her as a vibrant, loving person deeply missed by her family, friends, and her dogs. Donations in her memory have been suggested to the Bruyère Brain Health & Memory Clinic and the Griffin Bell Endowment Fund as a way to honor her.
