Prescott, Arizona - The investigation continues into the deaths of a Milwaukee man and two others at an Arizona sweat lodge.
Investigators say they are interviewing hundreds of people.
Authorities are treating the deaths as homicides and say self-help guru James Arthur Ray is the primary suspect, but that others are also being investigated.
Last month, Ray led the ceremony as part of his five-day "Spiritual Warrior Retreat."
Ray says he's hired his own investigative team to determine what went wrong.
The case is expected to go to prosecutors next month.
