The 23-member Jackson County grand jury unanimously returned a “no true bill” on Monday after reviewing an extensive investigation into the circumstances surrounding Wells’ death.

According to the Jackson County District Attorney’s Office, prosecutors presented the jury with phone forensic reports, GPS records, surveillance footage, information obtained through 132 subpoenas, and testimony from 43 witnesses.

The decision means no criminal charges will be filed based on the evidence currently available.

Wells was found dead in waters near Horn Island, Mississippi, on July 6, two days after traveling to the island with friends for a Fourth of July gathering.

Investigators determined Wells had traveled aboard a boat called The Triton, one of three vessels used by the group.

During the return trip, The Triton reportedly suffered a motor problem and bilge pump failure, causing the boat to take on water before another vessel had to tow it toward the mainland.

Authorities concluded that Wells remained behind on Horn Island when the boats departed.

One detail that fueled speculation surrounding the case was that Wells’ cellphone returned to the mainland without him. Investigators, however, noted that other passengers’ phones were also transported aboard separate boats and said they found no evidence that the phone’s location pointed to criminal activity.

Despite the grand jury’s decision, Wells’ exact cause and manner of death remain officially undetermined.

The Mississippi State Chief Medical Examiner and an independent forensic pathologist retained by Wells’ family both reached that conclusion.

Court documents reportedly state that an accidental drowning remains consistent with the available evidence, although neither examiner was able to definitively establish drowning as the cause of death.

Both examinations also identified bruising to the back of Wells’ head.

Investigators determined the injuries were not fatal and found no evidence of physical trauma severe enough to have caused his death.

One witness told authorities that Wells had slipped awkwardly while getting off a boat but continued socializing afterward and did not appear seriously injured.

Toxicology testing also reportedly found no cocaine in Wells’ system.

Investigators said Wells purchased alcohol using a fake identification document but found no evidence that adults over the age of 21 had illegally supplied alcohol to Wells or his friends.

The investigation also addressed several allegations that circulated online following Wells’ death.

Among them were claims that Wells had been involved in a fight before he disappeared and accusations of misconduct involving his friends or their families.

The grand jury ultimately determined there was no evidence showing criminal conduct occurred.

Authorities also examined viral photographs said to show Wells attending a pool party connected to the Fourth of July trip. Investigators determined those images were taken before the holiday.

Officials additionally reviewed audio circulating online that purported to capture a SeaTow call involving The Triton. Investigators said the viral recording differed from the original call.

Another allegation claimed that medical officials had improperly withheld major organs before Wells’ family arranged an independent examination.

The forensic pathologist hired by Wells’ family reportedly confirmed that standard procedures had been followed.

The grand jury ultimately found insufficient evidence to support allegations of foul play, leaving the case without criminal charges.

Still, the investigation is not necessarily permanently closed.

The Jackson County District Attorney’s Office noted that Mississippi has no statute of limitations for homicide, meaning the case could be brought before another grand jury if credible new evidence emerges suggesting Wells’ death involved criminal activity.
