RICHMOND, Va. — Two Virginia men convicted of setting fires that killed their children are seeking to clear their names.

Attorneys for 57-year-old Davey J. Reedy and 36-year-old Michael L. Ledford contend that the science used during the investigations in the late 1980s and 1990s was flawed.

But prosecutors stand by the men’s convictions.

Reedy received two life sentences for the deaths of his two children in a 1987 fire in Roanoke. He was paroled in 2009 and has a clemency petition before Gov. Bob. McDonnell.

Ledford is serving a 50-year sentence for the 1999 death of his son in a fire in Stuarts Draft. A clemency petition is being prepared for him.
