Authorities in Palm Beach County said Thursday that the baby found floating near the Boynton Beach Inlet likely drifted north from Broward County.
The infant, know as Baby June, was between four and seven days old, Palm Beach Sheriff's Office Capt. Steve Strivelli said in a press conference.
Investigators believe the baby was born between May 25th and May 28th. The infant appears to be African America, maybe Hispanic or mixed.
Previously, Capt. Strivelli, who works in the Special Victim's Unit, had said that authorities are investigating the "tragedy" as a medical examiner works to determine a cause of death.
"It's gut-wrenching. We hate seeing it. We desperately want to get to the bottom of what happened," Strivelli said. "We are asking anyone in the public who has any information about this case or what might have happened, about the parents or who they might be, to contact the PBSO."
An off-duty firefighter was boating near the Boynton Beach Inlet when he made the discovery on Friday.
