People on the scene all said they never imagined a woman could give birth that quickly.
But, timing was on the mom's side because a police cruiser happened to be driving by just as the baby was about to enter the world.
Inside that car was Philadelphia Highway Patrol Officer James Pembroke.
He just happened to be riding along the 1200 block of Huntington Street a bit after 5:00 p.m. Wednesday when he saw a bunch of people jumping and waving their arms, trying to flag him down.
The mother's cousin, Donnie Wells, was among the first on the scene and he says the baby's head was already crowning when Officer Pembroke arrived.
So, the officer had to do something he doesn't usually do - deliver a baby.
Wells told us officer Pembroke did a wonderful job calming the mom-to-be, 37 year old Olyn McCollum.
Pembroke says he simply went with his instincts. They got the mom into the back of his patrol car and that's where he completed the deliver.
As good fortune would have it, the next officer on the scene was Charles Waters, a former paramedic. He cut the umbilical cord and wrapped up the baby until paramedics arrived a short time later.
Mother and child are now doing just fine. Officer Pembroke had one final message for Mrs. McCollum, "Good luck. And if you ever need me again, just stand outside jumping and maybe I'll see you again."
