During work he helped save people's lives, and personal time police say he ruined lives.
For weeks police worked with a sketch of a man they believe sodomized an 11-year-old girl in her apartment building's elevator after she walked her dog.
But it wasn't until Monday that another rape victim came forward, this time with a license plate number.
Victim's neighbor says "He deserves everything he gets. Nothing less a whole lot more," said one of the victim's neighbors.
Police say 33-year-old Angus Pascall is the suspect in a string of five sex assaults.
Pascall lives in Brownsville and works nearby at a fire department paramedic in Canarsie.
Detectives say all the alleged rapes happened in that vicinity.
It started in 2001, a 22-year old woman says the suspect armed with a gun got in her East Flatbush home and raped her.
Then in May of last year, a 19-year-old woman says she was sodomized in her apartment building elevator also in East Flatbush.
In the third case, a 14 year old girl says she was sexually assault at gun and knifepoint in Canarsie.
Two weeks ago, an 11-year-old girl says she too was raped in Crown Heights
And finally a 20-year-old woman says she was walking down the street Monday, forced into a car in Canarsie and raped.
In two cases investigators say the suspect took advantage of his fire department special key to lock his alleged victims inside those elevators.
"It's a good thing they got him. He's a pedophile. We have a lot of children out here," adds the neighbor.
Police say three victim's positively identified Pascall and DNA points to a single suspect.
But his neighbors don't believe the accusations. "This guy can get any woman he wants. He has a body, he got a good look. He's a hard working guy and this is what it comes down to. I guess you never know," said Clem Williams.
Pascall is charged with rape, possession of a weapon and endangering the welfare of a child.
