Cause of Death for Missing Teen Confirmed by Medical Examiner in Florida Case

The cause of death for the missing North Carolina teen found in a Manatee County retention pond has now been officially confirmed. The medical examiner ruled the cause of death as drowning, with the manner of death classified as accidental. The case of the missing teen generated weeks of questions from the public, and officials say the findings close a major part of the investigation.

The confirmation follows extensive forensic work after 18-year-old Giovanni Pelletier disappeared in early August while visiting Florida. The medical examiner’s announcement addresses the central question families and authorities had been trying to answer about how the teen died.

Official Findings on the Cause of Death for the Missing Teen

The District Twelve Medical Examiner’s Office reported that Pelletier died from drowning and determined his manner of death as accidental. Officials said a forensic anthropological exam showed no signs of trauma or injury. Toxicological testing of liver tissue revealed only a small trace of ethanol, which the medical examiner noted is consistent with natural decomposition rather than intoxication. These findings were emphasized in the official review.

Investigators also evaluated video evidence collected from the area surrounding the retention pond. The footage showed Pelletier alone and moving through the area before his death. According to authorities, this aligns with the conclusion that no other person caused or contributed to the drowning. The sheriff’s office said the video supported the medical examiner’s findings and helped verify the timeline of events.

Pelletier had traveled to Florida from North Carolina to visit family in Englewood. According to investigators, he left around 1:30 a.m. on August 1 with a cousin and two of the cousin’s friends—individuals Pelletier had never met in person before that night. Text messages released by authorities show that Pelletier discussed smoking marijuana during the drive. Officials said he wrote that he had not used marijuana recently because of court obligations in North Carolina.

According to statements given to detectives, Pelletier smoked in the car during the early portion of the drive and began “tripping” shortly after. The cousin told investigators that Pelletier became agitated, “raging,” and acting erratically. The group stopped the vehicle on River Road so Pelletier could use the bathroom, but they said his behavior did not stabilize.

Authorities reported that while driving north on I-75, Pelletier sent several alarming text messages to his mother. The messages contained the word “Help” in separate, rapid succession. Moments later, investigators said Pelletier opened the car door while the vehicle was moving. Witnesses in the car told deputies that he shouted threatening statements, including “I am a demon and I will wreck this car,” and claimed he would harm everyone inside. According to the sheriff, Pelletier was known to carry knives.

The driver pulled over near State Road 70. Witnesses said Pelletier exited the vehicle, ran into the southbound lanes, then crossed into the northbound lanes, narrowly avoiding traffic. He reportedly left behind his backpack and cellphone. The individuals he was traveling with placed the items along SR 70 before continuing their drive to Brevard County.

Pelletier’s mother received the concerning texts but did not reach her son. Authorities said she later discovered the phone was moving toward Tampa, not knowing a truck driver had picked up the items on the highway. Tampa police eventually recovered both the phone and backpack after she reported the movement.

A missing person’s case was officially opened later that morning. When Pelletier’s remains were discovered in the retention pond, investigators focused on piecing together the sequence of events. The final medical examiner’s report now provides the clearest explanation of what happened in the hours after the teen fled from the vehicle.

Community Response and Broader Takeaways

The confirmation of the cause of death for the missing teen brings closure to a case that stirred widespread concern. Families in both North Carolina and Florida followed the developments closely, as did many online communities tracking missing-person investigations. Officials said the findings reinforce the importance of immediate reporting when young individuals exhibit signs of distress or altered mental states.

The sheriff’s office emphasized that the accidental drowning underscores the risks of impaired judgment, confusion, and panic—especially at night and near active roadways. Community leaders said the case serves as a reminder of how quickly high-risk situations can escalate and how complex missing-person cases can become when multiple jurisdictions are involved.

The medical examiner’s confirmation closes a difficult chapter for the family and authorities. The ruling on the cause of death for the missing teen offers clarity after months of uncertainty and speculation. Officials say the findings reflect a thorough, evidence-based review intended to provide final answers.
