KNOXVILLE, Tenn. (NBC News) - During his first few months on the job, FBI agent Troy Sowers found a missing baby who had been kidnapped. After 22 years of service, his colleagues decided to surprise him by reuniting Sowers with the child he found. 

In 1997, newborn Stewart Rembert was abducted from the hospital by a woman impersonating a nurse, according to NBC News. After the police and the FBI began their massive search, Rembert was found 19 hours later in a box next to a dumpster by Agent Sowers.

On Friday morning, the FBI celebrated Sowers' retirement. His colleagues tracked down Rembert, now a corporal in the Marine Corps, and invited him to Tennessee, according to NBC News. 

"It's crazy to think that without his efforts, I wouldn't even be here today," Rembert told NBC News just before the two met. "I wouldn't be a Marine. My family wouldn't be the same... I'm just super excited and honored to meet this man today."

Sowers said the reunion was "probably one of the best surprises I've ever had." 

Sowers explained how he had managed to find Rembert with the help of other law enforcement officials by convincing Rembert's kidnapper to tell them where the baby was. Sowers didn't think he would ever see the newborn again after they found him, according to NBC News. 

After Sowers was reunited with Rembert, he told him, "I'm glad [to see] what you've done with your life. Pass it on."
