Autopsy results show that Michael Philbin, the 21-year-old son of Green Bay Packers offensive coordinator Joe Philbin, drowned.
The Oshkosh, Wis., Police Department issued a preliminary report on Wednesday saying the cause of death was freshwater drowning, though no foul play is suspected.
Divers recovered Philbin's body on Monday 30 yards from the shore in the Fox River in Oshkosh, about 50 miles south of Green Bay.
According to ESPN, Philbin was last seen on Saturday while out with friends near the University of Wisconsin-Oshkosh when he separated from the group.
Police reports detail a call made by Philbin around 2 a.m. on Sunday to a friend in the group, but did not sound distressed. Friends called the police on Sunday about a half hour later when he never returned for his car nor contacted anyone.
A large search effort followed after a security guard at a nearby business near the Fox River phoned police to report someone calling for help around 2:30 a.m.
The death of Michael Philbin, the second of Joe Philbin's six children, comes days before the coach and the Packers prepare for Sunday's NFC divisional playoff game against the New York Giants.
The Philbin family's obviously going through a tough time right now, and as we always have, we're a family-first philosophy with our organization, with our program, said Packers coach Mike McCarthy during a Monday press conference. So we're supporting Joe and his family the best we can, and we're holding out hope that this comes to a positive conclusion.
Joe Philbin released a statement on Tuesday through the Packers.
We love Michael so much and will miss him dearly. He loved his family, friends and life. His memory will live on in the hearts and minds of all who knew him, Joe Philbin said. We are appreciative of the prayers and the support of our family, friends and the Packers family. We ask for continued respect and privacy for our family as we deal with our loss.
