Navy veteran John Bond, 77, was killed on Sunday after Thomas Jacob Sanford unleashed an attack on the Church of Jesus Christ of Latter-day Saints in Grand Blanc Police said Thomas Jacob Sanford opened fire on more than a hundred people who had gathered for a service at the Church of Latter Day Saints in Grand Blanc on Sunday Sanford got out of the pick-up with two American flags raised in the truck bed and started shooting, Police Chief William Renye told reporters. The attacker apparently used gas to start the fire and also had explosive devices but it wasn't clear if he used them, said James Dier, of the Bureau of Alcohol, Tobacco, Firearms and Explosives.One family friend told journalist Ty Steele that Sanford had been battling PTSD.'It's hard to feel sad for someone who did something so terrible, and I still feel sad. I had heard through family events that he had had PTSD,' she said.'He would make comments occasionally and it was something that was kind of talked about. It wasn't talked about in depth... so I don't know the depth of his issues.' Sanford's loved ones, including his wife and both of his parents, also frequently shared pro-Trump messaging on their social media pages. But investigators are still trying to establish a motive. Nearly a week before the horrific tragedy, Kris Johns, a resident running for city council, said he had a conversation with Sanford in which the shooter fumed about his hatred of Mormons. The city council candidate, who was canvasing the neighborhood at the time, said: 'He was extremely nice at first. He even talked about his child who had a serious medical concern. The charred wreckage of the building is still being searched as of Monday. It's pictured on Sunday after the attack'But when the conversation turned to religion, I just wanted to get off the door and away from him.'Johns said Sanford told him he previously lived in Utah - a state with close ties to Mormonism - where he had a brief relationship with a Mormon woman. Johns, who spoke to Detroit Free Press about the conversation with Sanford, who shared his struggles with drug addiction after his time in the service. The 44-year-old said 'it was one thing after another,' as Stanford went on to ask him if he believed in God. Johns, a Christian who is a member of the Solid Rock Community Church in Burton, replied 'yes' to Sandford, adding: 'From there, the conversation takes a very sharp turn.' He was then asked by Sanford about the Mormon bible, the role Jesus plays in the religion, the history of the LDS church, and more, Johns said. 'I just didn't know what the next question was going to be,' he added. 'There’s certain things you don’t forget. This is not a forgettable guy.'It was very much standard anti-LDS talking points that you would find on YouTube, TikTok, Facebook,' Johns said of Burton.As he went on to speak of the religion, Sanford told Johns that he had his tattoos removed so he could take part in church ceremonies. Several tattoos were seen on his arm in Facebook photos of Sanford, including barbed wire imagery and what appears to be a dreamcatcher.
