What was the biggest impediment to Wendy Wood's healing after the attack?

According to her daughter Adrienne Spore, the single biggest impediment to Wendy Wood's healing was not knowing who had attacked her and killed her husband of nearly 45-50 years. Wendy was described as strong and committed to getting justice for her husband after the brutal attack in Lake Tahoe. Adrienne explained that identifying the perpetrators would have enabled her mother to move beyond her grief and fully recover from the tragedy. Wendy's inability to know who was responsible prevented her from finding closure and healing from this traumatic event.
