Brissa Limones of Yuma, Ariz., was nine months' pregnant, only two weeks from her delivery date. Her two previous deliveries were quick and virtually painless. She nearly had her first child in K-Mart and delivered her second child in a pickup truck on the way to the hospital. Yearning for a short vacation before the baby arrived, Limones and her family decided, at the last minute, to travel across the border to Rocky Point, Mexico, for the Labor Day Weekend. Before they left, her uncle jokingly told Linomes to bring a pair of scissors.

On Saturday, the family spent several hours at the beach. But at 5 a.m. on Sunday, contractions woke Limones. She saw a doctor two hours later, who told her she had dilated to 7 centimeters, and urged her to have the baby in Mexico. Because Limones and her husband are U.S. citizens, they decided to risk the drive back to Arizona by way of the Lukeville Port of Entry.

At 8:00 a.m., when they arrived at the Lukeville port, Limones was already in labor. The Customs inspector working primary inspection motioned the car to secondary; another inspector called an ambulance hoping that paramedics would arrive in time. "I heard an inspector say that someone is having a baby in secondary inspection," says Osorio. Because of the EMT training he received in the Army, Osorio thought he could help with the delivery.

Osorio and other Customs inspectors brought Limones into the conference room and placed her on the floor. Everyone was nervous and waiting patiently for the ambulance to arrive. Osorio took Limones' vitals, asking her many questions such as how many previous pregnancies she's had and how far along she was in this pregnancy. Three park rangers from the Organ Pipe Cactus National Monument also came on the scene to help.

"We were all hoping that she would have the baby in the hospital, but all of a sudden her water broke, and I said, 'I guess we're having the baby here,'" explained Osorio. Supervisory Inspector Dwain Zimmerman raced to find clean towels for the delivery.

At 8:25 a.m., with one big push and the help of Osorio and Ranger Julie Horn, Annette came into the world, five minutes before the nearest ambulance arrived from Ajo, Ariz.

"He was great, he was awesome. I couldn't thank him enough," the new father said of Osorio. The Customs inspectors and park rangers who helped in the delivery, including Osorio, took turns holding the healthy 6-pound, 12-ounce baby girl.

Osorio was a fireman in Nogales before coming to Customs, and as a fireman, he delivered two babies. "I wasn't nervous at all, just surprised because I didn't think my job at Customs would ever involve delivering babies," says Osorio.

"Things like this happen at bigger ports, but never in Lukeville," says Zimmerman. "As far as anyone knows, this is the first time that a baby has been born at the Lukeville port."
