The widow of executed murderer Michael Richard has sued Texas Court of Criminal Appeals Presiding Judge Sharon Keller and unnamed defendants, alleging that Keller prevented the filing of Richard’s motion to stay his execution, resulting in his death.

Marsha Richard alleges in her original complaint in Richard v. Sharon Keller, et al., filed Wednesday in the U.S. District Court for the Southern District of Texas in Houston, that Keller ordered the CCA’s clerk not to accept paperwork concerning Michael Richard after 5 p.m. on Sept. 25. The state executed Richard later that day for the 1986 murder of a Hockley woman.
