A woman is dead after she was struck by a Philadelphia Fire Department ambulance late Thursday night, according to police.

The crash happened at the intersection of F Street and East Allegheny Avenue in Kensington. The police Crash Investigation Division was called to the scene about 10 minutes before midnight.

A South Philadelphia family wants answers after they identified the victim as 49-year-old Kelly Kissell.

"She just knew how to turn a frown upside down," said Kissell's son, Damian Benitez Jr.

The family of Kissell is remembering her as a woman who was full of life and someone who always led with kindness.

"She had a good character. She was so genuine, generous," said Benitez Jr.

The thought of losing her is still hard to fathom as the family continues to struggle with the crash that led to her death.

"I didn't want to believe it. I still don't believe it. That's why I think I'm so calm right now," said Kissell's sister, Stacy McCaffery. "We are in shock. I kept saying earlier there is no way. No way."

The family said Kissell was cleaning the street outside her home when it happened.

Police said no other vehicles were hit in the incident and that the ambulance was not responding to a call at the time.

Kissell was struck when the ambulance was making a right turn from Allegheny onto F Street, police said. The medics in the ambulance immediately requested additional assistance and administered emergency care to Kissell, according to police.

A second medic unit pronounced her dead at 12:01 a.m. Friday.

"We look up to police officers, ambulance drivers. We love them all. I support them. My family supports them. We're for them all the way. You need to do a better job," said McCaffery. "How can you not see what's right in front of you?"

The Philadelphia Fire Department released this statement on the incident:

"We are saddened by the incident overnight involving our medic unit and the death of a pedestrian. We offer our sincere condolences to their loved ones. The Philadelphia Police Department is leading the investigation and will complete a thorough inquiry into what happened. We will release further details when they become available."

While the investigation continues, the family is hoping for answers.

"I want some clarity. I just want to know where, when, why, how, who," said Benitez Jr. "I just want to at least know what happened."

Kissell's family said the 49-year-old leaves behind a son and two grandchildren, one of them she sadly never got the chance to meet.
