It may be weeks before authorities know exactly how and why New York Rangers enforcer Derek Boogaard died, although foul play was not immediately suspected.

The 28-year-old player was found dead Friday in his Minneapolis apartment. Few details were available, but the news rippled across the NHL, where the 6-foot-7 Boogaard was a fan favorite and one of the game’s most feared fighters. He missed most of last season because of a concussion and shoulder injury from a fight.

“I don’t think we have any answers as to what happened or why it happened,” Ron Salcer, Boogaard’s agent, said Saturday.

Authorities received a report of a man not breathing shortly before 6:15 p.m. Friday, Minneapolis police Sgt. William Palmer said. Minneapolis fire officials were the first to arrive and determined he was dead.

Palmer said authorities do not suspect foul play at this point, but the police department’s homicide unit and the Hennepin County Medical Examiner’s Office are investigating. Palmer said the medical examiner will decide the cause of death.

An autopsy was being conducted Saturday, but county spokeswoman Carol Allis said results probably will not be released for at least two weeks.

She said in cases with no obvious signs of physical trauma or an obvious immediate cause of death, it takes time to receive results of laboratory tests. Allis said the medical examiner’s office doesn’t anticipate releasing preliminary autopsy findings until all results are in.
