Lt. Jason Meier told the Free Press that the calls came in around 10:13 p.m. and paramedics arrived to the scene in 4 minutes and 38 seconds where they found Kivlenieks unresponsive. Kivlenieks was transported to Ascension Providence Hospital in Novi, where he was pronounced dead, Meier said.
Police appear to have redacted some of the audio from the phone calls, including the location of the incident.
While Novi police said an initial investigation indicated that Kivlenieks died after he slipped and fell while fleeing a hot tub following a fireworks malfunction, an autopsy performed Monday found Kivlenieks died from chest trauma from a fireworks mortar blast.
