JACKSONVILLE, Fla. -

Police are still searching for the husband of an 18-year-old mother found dead in her apartment Thursday.

Investigators suspect foul play in Rosa Garcia's death, but they have not released her cause of death.

They spent they day looking for several people, including her husband, to shed more light on what happened.

One man who lives in the gated apartment complex said he heard a loud noise, possibly a gunshot, and saw a flash of light, then heard running the night before Garcia was found dead.

Garcia worked at La Nopalera in Jacksonville Beach. While neighbors say they didn't know her well, they said they would often see Garcia, her husband and daughter outside.

"The (2-year-old) child is currently in our care," Department of Children and Families spokesman John Harrell said.

He said DCF is trying to figure out if the girl will be placed with family, and if she may have seen what happened to her mother.

"It's not clear what the child may have seen or may have witnessed," Harrell said. "Typically you're talking about children who are not verbal. We certainly hope that the child did not see what happened. It's a very tragic situation."

As police try to figure out what happened to the child's mother, they continue to search for her 20-year-old father, Garcia's husband.

Investigators haven't been able to find him and are looking for the family's car, a silver Nissan Altima.

Garcia's husband hasn't been named a suspect, and Channel 4 crime analyst Ken Jefferson says right now investigators just want to find out what he knows.

"He needs to just come forward and share with authorities what he knows, because he's giving the appearance that he's on the run and he's trying to avoid police," Jefferson said. "It's only going to make it difficult for him."

Police believe people in the community shouldn't be concerned. Jefferson said they should still keep their eyes open though and be on the lookout for the car and Garcia's husband, and call police if seeing him.
