JACKSON, Miss. (AP) -- An advocacy group and the brother of an inmate scheduled for execution Tuesday have filed a lawsuit to preserve evidence in the case for additional testing.
The lawsuit was filed after the FBI said there were flaws in the "microscopic hair comparison analysis testimony or laboratory report'' and offered DNA testing in the case of Willie Jerome Manning.
The 44-year-old Manning was sentenced to death in the 1992 slayings of two students. Manning says that hair found in one victim's car was not proved to be his.
Mississippi Attorney General Jim Hood has said DNA testing wouldn't exonerate Manning.
The Innocence Project of Mississippi and Manning's brother filed a lawsuit Friday in Oktibbeha County Chancery Court to prevent the destruction of evidence in the case, whether he's executed or not.
