Firefighter Robert Alexander always followed in his father’s footsteps — even in death.
The 43-year-old — who worked on FDNY fire boats — died Monday of a brain tumor stemming from his time at Ground Zero.
For Alexander, succumbing to a 9/11 illness is a heartbreaking family affair — a year earlier, his father Lt. Raymond Alexander, died of cancers linked to his time on the pile, FDNY sources said.
"World Trade Center illnesses continue to take the lives of far too many FDNY members, now including two generations of the Alexander family — a father and son who served so bravely, for so long,” FDNY Commissioner Daniel Nigro said Wednesday.
