Following the April 29th execution of Clayton Lockett, the Tulsa World, along with legal representation from The Reporters Committee for Freedom of the Press, filed a lawsuit against the state of Oklahoma. On Friday, more than 5,000 pages of interview transcripts and other records were released.

The transcripts include about 100 interviews the Department of Public Safety conducted with witnesses during its investigation into Lockett’s execution. However, some of the records are heavily redacted without explanation from the DPS.

A hearing in the World’s lawsuit is set for March 27 in Oklahoma County District Court.
