• Arya Singh, 29, was arrested Thursday based on DNA evidence
  • The baby's father told cops he had a girlfriend at the time who was pregnant
  • The infant's body was found floating in the water near Boynton Beach in June 2018

A Florida woman was arrested for the death of her newborn, four years after the cops found the body of the infant, "Baby June," floating in the ocean near Boynton Beach.

The Thursday arrest was the latest in an investigation that began after an off-duty firefighter spotted the newborn floating in the water on June 1, 2018. The infant girl was given the name "Baby June," and her details were entered into CODIS, the national DNA database.

Even after initially checking with more than 700 babies born during that time, the police had no leads in the case. However, the investigation eventually led to the suspect, identified as 29-year-old Arya Singh, after cops successfully traced the baby's potential father, who helped them in the probe, NBC News reported.

The unidentified father told the cops that he had a girlfriend around that time who was pregnant. However, the man never knew he had a baby and reportedly thought his girlfriend had an abortion, police said.

Baby June's DNA matched with Singh's after investigators tested them through a piece of garbage without notifying her about the discovery until she was arrested Thursday.

"The men and women in law enforcement always think they're tough and they've seen it all. But I guarantee you when you see an infant — a newborn infant, floating in the ocean that somebody has discarded like a piece of trash — it tugs at your heart," Palm Beach County Sheriff Rich Bradshaw said in the press conference, applauding the dedication and effort made by the investigating team.

Meanwhile, Singh claimed that she was not aware of her pregnancy until she gave birth in a hotel toilet on May 30, 2018. "She said that when the baby was born, she wasn't sure if the baby was alive or the time the baby went into the inlet she was already deceased," police said.

Investigators have not revealed further details of the case but believe Singh is the sole suspect and plans to charge her with first-degree murder, reports said.

Singh is expected to have a first appearance in court Friday.
