The umbilical cord was still attached to the baby, FOX Tampa reported. 

Authorities also released an image of a red sedan. 

"The medical examiner is in possession of the child," Lakeland Police Chief Sam Taylor said. "Detectives and police are out there canvassing the area to find any information they can that will lead them to who put the child in the dumpster."

Taylor said he believes the newborn was in there for less than 10 hours. It's unknown whether the child was a stillborn or a victim of homicide, he said.
