Firefighter Michael Lubig was a man whose colleagues say lived his life with no fear.
The 46-year-old, second-generation fireman died late Monday, days after suffering a medical emergency at a west side firehouse and being rushed to Henry Ford Hospital.
Detroit Fire Commissioner Eric Jones said the cause of death is under investigation, and the incident unfolded during a 24-hour shift Thursday while Lubig was working a detail as an acting sergeant at Squad 4 on the city's west side.
That day, Lubig and his crew had battled three fires and gone out on a medical run.
Jones said Lubig's fellow firefighters worked on him before EMS transported him to the hospital.
