A routine traffic stop on a South Seattle street early Sunday put officers right in the midst of the miracle of childbirth.

Around 3:45 AM, Officer Anthony Reynolds saw a car running red lights and speeding down Martin Luther King Jr. Way S. When he pulled the car over at MLK and S. Graham Street, the driver jumped out of his car and shouted that his wife was in labor.

Officer Reynolds called for an ambulance, but the couple’s baby was determined to beat medics to the scene. Officers Lorissa Johnson, Nicholas Kartes and Jason Alvord joined Officer Reynolds at the scene, just as the couple’s baby girl was born. After first giving a full-throated cry as she burst into the world, the young girl began struggling to breathe. With the help of the child’s mother, Officer Reynolds cleared the baby’s airway and got her breathing again.

Medics arrived and transported the mother and child to a nearby hospital in stable condition. They’re doing well, according to the family, who took the time to send along a nice note thanking officers for their work. “You have helped deliver a precious gift,” they wrote. “we are so grateful.”

Update: Here’s the letter the family sent to the department:
