SEDONA, AZ (WTAQ) - Closing arguments in the trial of a self-help author in Arizona will continue for a fourth day next Tuesday.

James Arthur Ray is accused in the deaths of three people, including one from Milwaukee.

Ray led a sweat lodge ceremony in a rural area near Sedona, Arizona, in October 2009 to conclude his week-long "Spiritual Warrior" seminar.

His attorney argued Friday that authorities messed up the investigation and that prosecutors had failed to follow up on the possibility that there were other factors in the deaths.

Forty year old James Shore of Milwaukee was one of the victims.

Prosecutors will offer their closing arguments next week.
