CORAL SPRINGS, Fla. -

A missing 1-month-old boy is found dead in a car, and his father is taken into police custody, the Broward Sheriff's Office said Friday.

An Amber Alert was issued Friday for 1-month-old Josiah Saintil, whom police believe was abducted by his father, Janus Saintil, 24, of Deerfield Beach, on Thursday.

The Broward Sheriff's Office said Saintil was believed to be traveling in a stolen black 2008 Kia Spectra with Florida license plate No. K52-8LH.

On Friday afternoon, Coral Springs police said, the body of a child was found in the car at 11000 Royal Palm Blvd. in Coral Springs.

Coral Springs police said that Janus Saintil was taken into custody. BSO said Friday afternoon that investigators have identified the deceased child as Josiah Saintil.

"When you say you've seen it all, this is one of those things. Obviously, it was almost like the baby was carelessly discarded inside the trunk, a total lack of respect for the baby's life," said Broward County Sheriff Al Lamberti.

BSO said the incident began Thursday night, when Janus Saintil was going to a North Lauderdale Walmart with his girlfriend, Claudia Harriott, 22, their son and two friends, Marissa Murray, 22, and Andrew Pennent, 22.

Saintil and Harriott got into a fight and Saintil took out a gun, according to the sheriff's office. Saintil then forced Harriott and and the two others to drive to Port St. Lucie at gunpoint with the baby. Saintil dropped the baby off at a house and then drove to a second house and an ATM, detectives said.

Saintil tried to force Pennent to take out cash from the ATM, and when he refused and yelled for help, Saintil fled in the Kia that belonged to Murray's mother, according to investigators.

Coral Springs police, with help from the U.S. Marshals Service were able to trace Saintil to the Palm Trace condominiums. An officer was waiting there when Saintil pulled in around 2:45 p.m. Friday. He and an 18-year-old woman were taken into custody. The officer found the baby shortly afterward as he searched the car.

Lamberti explained what will happen next.

"We're doing some crime scene investigation. At some point here shortly, we are going to transport the entire vehicle, intact, to the medical examiner's office. At that point, an autopsy will be done, more crime scene work to determine exactly the cause of death, which we do not know yet, and then we'll go from there," Lamberti said.

Saintil, wearing a white jumpsuit, was taken to the Broward County jail shortly after 11 p.m. Friday night.

Police said he faces charges of first degree murder and armed kidnapping.
