Wyoming, MI — Police say a rowdy visitor at a Grand Rapids-area hotel set up a phone to try to record the fatal shooting of a security guard who was sent to remove him. The 21-year-old gunman then went to his mother’s house nearby and killed himself. The incident occurred Tuesday at the Grand Rapids Inn in Wyoming. The security guard was identified as John Cain Jr. The 21-year-old gunman was identified as Jacob Grygorzyk. His video was posted on social media but subsequently removed. Wyoming police say the video didn't show the shooting, but shots could be heard in the background.
