Alonzo Brooks, a 23-year-old mild-mannered man, attended a party at a rural house outside La Cygne, Kansas on April 3, 2004, and never returned home. His family organized a search party of approximately 50 volunteers, and on May 1, 2004, they discovered his body in brush along a creek in Linn County.
