The little girl had been alive for a week or less when she was found floating in the Atlantic Ocean off the coast of Florida.

Forensic analysis has determined that strong coastal currents pulled the tiny body of the child, now dubbed "Baby June," for miles—meaning a wider search area than previously believed, according to authorities.

The little girl was likely placed in the water in Broward County to the south, and the remains drifted for 20 miles or more, according to Capt. Steven Strivelli of the Palm Beach County Sheriff’s Office.

The body was in the water for anywhere between 6 and 18 hours—in which time it traveled the distance, the investigator added at a Thursday press conference.

“It’s scientifically-based, but I don’t want to discuss how we’ve arrived at (that finding),” said Strivelli. “We’re full steam ahead with Broward County.”

The girl was found last Friday at 1 p.m., partially submerged on the ocean side of the Boynton Beach Inlet, by an off-duty firefighter. The remains were between 75 and 100 feet off the shoreline.

Based on the timing and condition of the body, the child was born sometime between May 25 and 28.

The child also had pricks in her heels that were noticed at autopsy—meaning she had routine neonatal tests performed on her. While that means it’s likely that she was born at a hospital, the child could have also been delivered at home or a private birthing center and brought to a place where she received medical attention afterward.

The child is neither Caucasian nor Asian—and could be mixed-race, black, or Hispanic.

The cause and manner of death have not been released by authorities—and particularly whether the child was already deceased when she entered the water.

The relatively quick discovery means that decomposition was likely limited, according to the forensic literature. Bodies will float in warm water for approximately eight to 10 days, and water initially slows down the processes of decay, according to Practical Homicide Investigation, the standard textbook authored by retired NYPD “murder cop” Vernon Geberth. But other factors that come into play with investigating “floaters” include marine life effects, and currents—which can both disfigure remains, according to the text.

Sheriff Ric Bradshaw also announced this afternoon that there is now a $10,000 reward for anyone who provides information leading to an arrest in connection with the death of the baby.

Investigators said they cannot rule out that the baby may have come from a “migrant boat” in the region.

Anyone with information on the death is asked to contact the Palm Beach hotline: (561) 688-4155.
