Denton County Sheriffs Deputy Jason Quigley made a U-turn to stop a speeder in a pickup on Farm Road 2449 Monday, and ended up helping to deliver a baby.Deputy Quigley was westbound on the road when an eastbound pickup whizzed passed him at 97 miles an hour, sheriff's spokesman Tom Reedy said in a news release. Quigley turned around and stopped the truck, expecting to issue a ticket for exceeding the 55 mph speed limit.But Jeremy Smith of Ponder leaned out the driver's side window and yelled that his wife was about to deliver.Quigley notified dispatch, who notified paramedics at a nearby Denton fire station, Reedy said in the release.But Jessica Taylor said her baby couldn't wait. So both men hastened around to the passenger's side and caught the baby as it came out.Quigley got a new raincoat from his patrol car and wrapped the baby in it, Reedy said. Denton EMS paramedics arrived within minutes, and gave the father instruction on cutting the umbilical cord, the spokesman saidJayden Leigh Smith, a girl, was born at 8:38 a.m., according to dispatch call notes. She weighed 6 pounds, 13 ounces, and is 18 ½ inches long, Reedy said.Jeremy Smith said he was headed to Denton Presbyterian hospital when he was stopped. When he saw the red lights flashing in his rearview, he thought, "OK, here's our escort.""Once he told me the situation, my main concern was getting medical help," Quigley said. "From the time I stopped the vehicle until she gave birth was less than a minute. And there's no telling what would have happened if she had given birth while they were still en route, especially driving at that speed."Mother and baby were transported to Presbyterian Hospital of Denton, where both were reported doing well, Reedy said.
