FILE - In this April 18, 2013 aerial file photo are the remains of a nursing home, left, apartment complex, center, and fertilizer plant, right, destroyed by an explosion in West, Texas. The families of 15 people that died in the plant explosion, 12 of them trying to respond to the initial fire, have spent the last year navigating the difficult balance between seeking answers and finding closure. Lawsuits filed in the weeks afterward are mired in a complex legal process that could uncover new details on the incident through testimony, but key questions will remain unanswered for many months to come.
