The body of a missing Florida Gulf Coast University student has been recovered from a lake on the campus, authorities say.
His body was found on Thursday after a 12-hour overnight search, Sheriff Marceno said.
McGrath did not have any visible signs of physical trauma, and his cause of death will be determined by a medical examiner, he added.
Thirteen other people were onboard the boat when McGrath fell overboard, the sheriff said. The group had been “having fun enjoying themselves” prior to the accident, the sheriff said.
All 13 were being interviewed independently on the night of the accident. The wake boat had a capacity of 16 people.
A multi-agency rescue effort consisting of dive teams, helicopter, marine boats, and drones were deployed to search for the missing teenager on Wednesday night.
When daylight broke on Thursday, the Lee County Sheriff’s Department’s Marine Unit & Underwater Operations used a boat with side-scan sonar to search the lake bed for McGrath.
Sheriff Marceno confirmed McGrath’s body had been found in a statement on social media at around midday.
“Our thoughts and prayers are with Graham’s family and the entire FGCU family,” he said.
The circumstances of his death are under investigation.
In a statement, Florida Gulf Coast University president Aysegul Timur said the “entire FGCU community” was devastated by McGrath’s death.
“It is with deep sadness that I inform you of the passing of Graham McGrath, the FGCU student who tragically went missing yesterday afternoon while on a private boat on the shared lake between the university and Miromar Lakes.”
Ms Timur thanked the Lee County Sheriff Office, the Florida Fish and Wildlife Conservation Commission, the Iona-McGregor Fire District, San Carlos Park Fire District and the university’s police department for their efforts in locating the student.
Counseling services were available to grieving students and taff, she said.
“During this time of great heartbreak and grief, FGCU wants to help our students, faculty and staff the best that we can. We encourage everyone to seek the assistance they need.”
McGrath died one week before his 20th birthday.
