(CNN) -- Investigators were searching Monday for two people who were discovered in a car in New Mexico with a 5-year-old boy who was reportedly kidnapped from Missouri, police said.
The boy -- Devon Denman -- was taken from Lake Ozark, Missouri, said Lt. Eric Garcia of the New Mexico State Police. The boy is safe and is in police custody.
Police are searching a 200-mile area around Gallup, New Mexico, west of Albuquerque, for Elizabeth Denman and Mark A. Cochran, Garcia said.
Elizabeth Denman is believed to be the young boy's mother, Garcia said. The other person police are looking for, Mark A. Cochran, is a registered sex offender, according to the Missouri State Highway Patrol website.
Both are considered "armed and dangerous," said Garcia.
Police found the boy after they pulled over a car Monday morning for having a busted tail light, they said. A trooper approached the car after determining it was stolen, but the vehicle drove away and a pursuit began, said Garcia. Several shots were fired at police during the chase, Garcia said.
Speeds during the chase exceeded 100 mph, he added. The vehicle eventually ran over stop sticks -- a device police use to puncture tires and stop chases -- and the tires blew out, Garcia said. No one was injured in the shooting, he added.
Devon was found in the back seat of the vehicle, unharmed, Garcia said.
