PALM BEACH, Fla. (WFLA) – Four years after the body of an infant was found in the ocean off the coast of South Florida, an arrest has been made in connection with her death.

On Thursday afternoon, the Palm Beach County Sheriff’s Office announced that the mother of “Baby June,” Arya Singh, 29, has been arrested and charged with first-degree murder.

Detective Christoffel stated that when she received this case, they had just got a lead generated from the crime lab about a potential father.

“We got the DNA from the father, he was very corporative, he knew nothing about the baby,” she said. “He knew that he had a girlfriend around that time that told him she had been pregnant but had taken care of it. He was thinking she had an abortion.”

After the DNA was tested, it was confirmed he was the father. This led police to a possible suspect as to the mother.

The detective stated that they were able to get Singh’s DNA from a piece of trash and confirmed she was the mother with a second sample.

Over the next several months, investigators began building their case and obtained search warrants for phone and GPS records.

“We learned that she was at the Boynton Beach Inlet on May 20, 2018, about 40 hours before we located this baby,” Christoffel said. “She searched local news for days and months after. She did see the first articles on June 1, around 5 p.m. and she never came forward after all this time.”

After interviewing Singh, several friends, and family members, it was determined that she was solely responsible for Baby June ending up in the Boynton Beach Inlet.

According to authorities, Baby June, born on May 30, 2018, was already deceased by time she reached the inlet.

Singh never named the infant.

Baby June was found when an off-duty Boynton Beach firefighter saw a body of a female infant while out boating near the Boynton Beach Inlet.

A medical examiner had ruled the case a homicide. It was determined that the baby was no more than 14 days old. She had a needle prick to her heel and her umbilical cord had been cut.
