Police in Novi, Michigan, said Monday that 24-year-old Columbus Blue Jackets goaltender Matiss Kivlenieks died after hitting his head following a Fourth of July fireworks accident. Lt. Jason Meier of the Novi Police Department said a mortar-style firework tilted slightly and started to fire toward people nearby. Kivlenieks was in a hot tub and fled along with several other people, but he slipped and hit his head on concrete, Meier said. The fire department and EMTs got to the private home about 10:13 on Sunday night and took him to a local hospital, where he was pronounced dead, Meier said. An autopsy is scheduled for Monday. "At the moment, we're pretty certain this was a tragic accident," Meier said.
