Update: At 6:44 p.m. Tuesday, the Griffith family released a statement through Kim Savage, the Sarasota Memorial Health Care System's media contact.
The statement read:
"Indiana University freshman Isaac Griffith remains in a medically induced coma in Sarasota Memorial’s Critical Care Unit. His condition is critical, but stable. Doctors say he is showing small, but incremental improvements.
Isaac’s parents, Shannon and Kim Griffith are by their son’s side and deeply grateful for the prayers and support from friends and followers across the states. They have asked for privacy during their son’s recovery and shared the following statement:
'We deeply appreciate the prayers and outpouring of support coming to us through tweets, calls and messages, both from Florida and Indiana. We are seeing positive signs throughout the day and winning small battles that give us hope.'”
Update: At 10:13 a.m. Tuesday, the IDS received the incident report from the Sarasota County Sheriff’s Office. The incident was reported at 7:31 p.m. Monday.
According to the report, Griffith consumed alcohol in his hotel room before going to Siesta Beach. While in the water, the current pushed him away from shore, and he was reportedly taken about 15 yards away from the swim buoy, where he started to go into distress.
The report said Griffith's friend Mitch McCune rescued him and brought him back to shore, where he had a pulse but was unconscious. His breathing was reportedly short and sporadic so McCune performed CPR while 911 was called.
The report read "the hospital later reported Griffith's CAT scan results came back normal which is promising."
According to the report, IU football senior wide receiver Nick Stoner and redshirt freshman safety Ty Smith were also drinking with McCune and Griffith, and were also there with them when the accident happened.
Update: At 6:45 a.m. Tuesday, Shannon Griffith tweeted that he and Kim have been at Isaac's bedside in the intensive care unit since 2 a.m. His father said Isaac's vitals are stable but the freshman is still in a medically induced coma and is on a ventilator to help his lungs heal.

Editor's note: The word "burials" in Shannon Griffith's statement was likely auto-corrected from "vitals."
