Police had been searching the east coast of Florida for Josiah Saintil, who would have been 2 months old next week. The Florida Department of Law Enforcement and Port St. Lucie Police issued an amber alert after he was reported missing Friday in Port St. Lucie.
Coral Springs Police Chief Tony Pustizzi said Friday investigators think they know the identity of the body found in the car on a Coral Springs parking lot, the South Florida Sun Sentinel reported.
Formal identification will be made by the Broward County Medical Examiner's Office.
Janus Saintil Jr., 24, was in custody late Friday, police said. Investigators found the body after tracing Janus Saintil's movement from North Lauderdale to Port St. Lucie and then back to Broward County the Sun Sentinel said.
Josiah Saintil had been taken to Port St. Lucie after a domestic dispute that turned violent Thursday night in North Lauderdale, the Broward County Sheriff's Office said. Janus Saintil was driving in a car with the baby, the baby's mother and two other adults when an argument broke out and Janus Saintil drew a gun, the sheriff's office said.
Police said Santil abducted the three adults and dropped the baby off in Port St. Lucie. Police said an accomplice helped Janus Saintil try to force one of the kidnapped adults to pull cash out of an ATM, but drove away after the man yelled for help.
It was not known what happened to the other two kidnap victims, the newspaper said.
