A prosecutor says authorities may never know why a south Alabama man killed a school bus driver and held a 5-year-old boy hostage for six days in an underground bunker.
District Attorney Kirke Adams said Friday that 65-year-old Jimmy Lee Dykes wanted to go on live television to make a statement, but he never told negotiators exactly what he wanted to say.
Dykes was due in court the day after the standoff began for a hearing on a menacing case filed in December after he allegedly fired a gun at neighbors.
Meanwhile, authorities are digging around the site where Dykes held the boy hostage before he was killed in an FBI operation that rescued the boy.
Aerial photos taken by The Associated Press show workers have partially excavated the bunker constructed by Dykes.
