INDIANAPOLIS (AP): A man given three death sentences for the slayings of his wife and two teenage stepchildren in the family's Gary home is appealing his case to the Indiana Supreme Court.
 
       Among 48-year-old Kevin Isom's chief arguments is the fact that he can only die once.
 
       A Lake County jury convicted Kevin Isom last year in the 2007 shooting deaths of his 40-year-old wife, Cassandra, 16-year-old Michael Moore and 13-year-old Ci'Andria Cole.
 
       Defense attorney Mark Bates is asking the Supreme Court on Thursday to throw out Isom's death sentences or grant him a new trial.
 
       A judge declared Isom's first trial a mistrial following issues over jury selection.
 
       Isom is one of 13 inmates held on Indiana's Death Row.
