A Memphis judge ruled Monday that the estate, represented by April Alley, lacks standing to request the testing.
Alley is the daughter of Sedley Alley, executed in 2006 for the murder of Marine Lance Cpl. Suzanne Collins.
April Alley petitioned for the testing after investigators in a Missouri murder case contacted the Innocence Project about a possible connection between another suspect and Collins.
A statement from the prosecutor reads, “After 34 years of appeals by the defense, the Collins family continues to be the only victim in this case.”
Alley’s attorneys have filed a notice that they will appeal.
