In Michigan, a Sunday service turns into a battlefield. Thomas Sanford, a 40-year-old veteran of the US Marines, struck a church with his truck, fired an assault rifle, and then set the church on fire with gasoline. At 10:25 a.m., the attack started. Police showed up in a mere 30 seconds, which was an amazing response. Just 8 minutes later, Sanford was shot and killed by officers. At least four people were killed and eight others were injured in the horrifying attack. >> Well, I couldn't believe it. I just could not believe it, man. Cuz that guy was a good guy, man. He never had no problem when he came over here and he was friendly as heck. >> The building was completely destroyed by the fire and it partially collapsed. Due to the presence of suspected explosives in his truck, the FBI has classified it as targeted violence. A community is left wondering why as they look for a reason, a political motive or a personal breakdown? Drop your theory in the comments.
