Extensive fire damage and the structural collapse of the home at 1430 N. 119th St. make it impossible to determine the cause of the fire that killed John K. Lorentz, 50, on Aug. 18, officials have said.
According to a statement released by Wauwatosa Fire Chief Rob Ugaste:
The state fire marshal has concluded the investigation, which did determine that the fire began in the northeast portion of the second floor.
The medical examiner's report states that Lorentz died of smoke inhalation and thermal injuries. A toxicology report is pending.
