Law enforcement officials have shared further details about human remains found in a Florida nature reserve this week, specifying that a “badly decomposed” portion of a human skull were found in area that had been until recently been underwater.

According to WFLA, two law enforcement officials told NBC News that “a portion of a human skull, badly decomposed” was found at the Carlton Reserve on Wednesday, over a month after Laundrie’s parents say he went for a hike there on September 13 and didn’t return. The human remains are pending a positive identification.

“I don’t know when the ID process will be complete,” Dr. Russell Vega, the chief medical examiner for Florida’s Twelfth District, told WFLA.

As previously reported, Laundrie’s parents returned to the environmental park that is adjacent to the Carlton Reserve on Wednesday, just after it was re-opened to the public. The parents are believed to have been the first to find articles belonging to Laundrie. A backpack and a notebook were reportedly found near the remains.

It is unclear if investigators discovered any remains beyond the partial human skull. News Nation Now reporter Brian Entin posted on Twitter that police officers went to the Laundrie family home in North Port on Friday, but stayed for only about two minutes.
