(AP) Three people were arrested on charges of swapping a 5-month-old boy for a downpayment on a used Dodge Intrepid and cash, police said Tuesday.

Nicole Uribe, 23, is accused of trading the baby to Jose-Juan Lerma, 47, and his wife, Irene, 27, in exchange for $1,500, $500 which was to be the downpayment, Pueblo police Sgt. Brett Wilson said. Details of the dollar amount were first reported by The Gazette.

The asking price for the baby was initially $10,000, but that later dropped, Wilson said quoting an affidavit. Wilson said negotiations were still under way and it was unclear whether future payments on the 2000 car for Uribe were part of the deal.

All were arrested on suspicion of felony trafficking in children and were being held at the Pueblo jail under $50,000 bail each.

The baby was placed in a foster home, Wilson said. Wilson said he couldn't speculate on the motives for the alleged deal.

He said police found the child and arrested Uribe within hours of getting a tip on Monday. The Lermas were arrested on Tuesday.

Wilson said all three were Mexican nationals and federal officials had been asked to investigate their immigration status.
