Authorities confirmed on Tuesday night that a body found inside the trunk of a white, Mitsubishi Eclipse was that of Ebony Jackson, News9, a broadcast station in Oklahoma, said.

The Oklahoma City mother went missing in St. Louis. Her three-month-old baby was found abandoned at an apartment complex last Friday, authorities said. The St. Louis Metropolitan Police department said on Wednesday at a news conference that there was some trauma to the woman's body, possibly indicating foul play.

While the baby was found safe inside a Breckenridge Hills apartment complex, authorities said the woman had not been heard from since last Thursday. It remains unclear how the baby ended up inside the apartment complex.

Jackson was visiting friends in East St. Louis, police told News9. Her family members said that she had phoned a cousin who lives in St. John and left a message on his cellphone that she was going to visit him. She never arrived.

Jackson's car was found in the 4400 block of Elmbank in North St. Louis on Tuesday morning, News9 reported.

"It's just totally out of character for her to be in a neighborhood like this, or just the car being in a neighborhood like this," a family member told the news broadcast station.

Her family members said that they have determined she made a phone call from Fairview Heights, where she was with a friend, although the identity of that friend remains unknown, they said

A spokesperson for the St. Louis Metropolitan Police Department confirmed the department`s involvement in the homicide case, but indicated there were still questions about where the woman was murdered.

A Fox News affiliate in St. Louis reported that he baby has been taken in to state custody, pending the results of a paternity test taken by a man identifying himself as the father. The two reportedly had a stormy relationship, multiple media accounts said.

Police said they are also examining the woman's arrest history in Oklahoma City. Local police said that Jackson has been arrested three times since 2005, including once for assault and battery on a police officer.

On Nov. 27, 2012, Jackson's most recent arrest in Oklahoma City, police said she used her son's stroller to hide merchandise at an area Wal-Mart. Jackson was confronted, and arrested, when she walked out, they said.

In 2011, she was allegedly caught stealing at a Dillard's Department store at Quail Springs Mall.

The woman's family has reportedly told police that she suffered some sort of previous brain injury, which causes her not to remember things.

Police said that they are looking for leads in the case and encouraged anyone with information to send it through the St. Louis chapter of CrimeStoppers.
