ST. LOUIS, Mo. (KSDK) - The body of a 30-year-old suspected of abandoning her infant son last week in a Breckenridge Hills apartment building was found dead in the trunk of her own car.

Ebony Jackson's 2004 Mitsubishi Galant was found Tuesday around 10 a.m. in the 4400 block of Elmbank Avenue.  The car was located via GPS.  The vehicle was towed to a secure location so police could begin a thorough search.

Jackson's 3-month-old baby was discovered in the hallway of the Hickory Trace Apartment building in the 3500 block of Dehart Place on the night of Friday, January 4.

A man from Oklahoma claiming to be the father of the baby said Ebony Jackson left with their son and was headed to Missouri. That man came to St. Louis earlier this week to take a paternity test, the results of which are still pending.

The St. Louis Metropolitan Police Department did not identify a cause of death.  An autopsy will be peformed to ascertain that information.

Meanwhile, Pine Lawn Police Chief Rickey Collins called NewsChannel 5 to say he would be going to the corner of Jennings Station and Natural Bridge roads Wednesday from 9 a.m. to 3 p.m. to collect $5,000 to put as reward money for information leading to the arrest and conviction of Ebony Jackson's killer.
