Oklahoma must give death row prisoners suing the state more information about a new lethal injection protocol released in February.

Judge Stephen Friot of the U.S. District Court for the Western District of Oklahoma ordered officials on Tuesday to give the inmates all available information about execution training by June 5 and to update them as changes are made.

The inmates reopened a lawsuit challenging Oklahoma’s lethal injection process after state officials announced the new protocol. Their next filing is due July 6.

OKLAHOMA CITY (AP) — Attorney General Scott Pruitt has asked a state appeals court to set an execution date for a man convicted of killing his former girlfriend and her two children.

Pruitt asked the Oklahoma Court of Criminal Appeals Monday to set an execution date for 39-year-old Michael Edward Hooper. Hooper was convicted of three counts of first-degree murder and sentenced in Canadian County to die for the 1993 shooting deaths of 23-year-old Cynthia Jarman and her children, 5-year-old Tonya and 3-year-old Timmy. Each was shot twice in the head.

OKLAHOMA CITY (AP) — An anti-death penalty group says a man scheduled to be executed next week is mentally impaired and wants Gov. Mary Fallin to reconsider clemency.

The Oklahoma Coalition to Abolish the Death Penalty wants Fallin to reconsider her denial of clemency for 56-year-old Garry Allen. The state Pardon and Parole Board in 2005 recommended the governor commute Allen's sentence to life in prison without parole.

But after reviewing the case, Fallin last month rejected that recommendation and ordered the execution to be carried out on April 12.
