FORT WAYNE, Ind. (AP) _ A Fort Wayne man on Indiana’s death row for his conviction in the fatal 1997 shootings of four men has lost his latest appeal.
 
  A federal judge in South Bend last week denied Joseph Corcoran’s death sentence appeal, finding that he failed to show that Indiana’s decisions to uphold the death penalty in his case were contrary to decisions by the U.S. Supreme Court.
 
  The Journal Gazette reports Corcoran’s attorneys said they plan to appeal. Corcoran’s case has been reviewed by the U.S. Supreme Court twice, a federal court twice and the Indiana Supreme Court five times.
 
  The now 37-year-old Corcoran was convicted in 1999 of killing his brother, his sister’s fiance and two other men in July 1997. His attorneys have said he was mentally ill.
