By Colleen Jenkins Feb 13 (Reuters) - The mother of the Alabama boy who was kidnapped from his school bus and held in an underground bunker for six days said on Wednesday she had not been allowed to speak with him during his captivity and worried that he would think she had abandoned him. Jennifer Kirkland said in an interview on "The Dr. Phil Show" that she had found some comfort in knowing that her son Ethan's abductor had cooked him chicken meals and asked law enforcement to fetch a red toy car he said the boy missed.
