Sarah Jenkins radioed it in from the corridor and they had Delilah in the ambulance in under two minutes, and Charlotte went with her, and I sent Pearl in the front of the truck because that little girl was not going anywhere without an adult who had been kind to her.

Nine days later, an emergency physician at the children’s hospital told a detective that the difference between a good outcome and a very different one had been “somewhere between forty and ninety minutes.”

Charlotte walked two point four miles.

I have done that walk.

It took me fifty-one minutes at an adult pace in dry weather, and I stood at the corner of Twenty-Sixth for a while afterward, because that is where she would have had to cross four lanes with a sick child.

Pearl Achebe told me afterward what happened in that break room in the eleven minutes I was in the lobby, and I put it in a supplemental report the next morning because it turned out to matter.
