Scott Peterson has asked the California Supreme Court for more time to appeal his death penalty conviction.
Peterson's lawyer sought the extension Friday - the deadline for the automatic appeal. It was the second such request made by Peterson's lawyer Cliff Gardner.
The court did not immediately respond to the request.
All death penalty cases are reviewed by the state Supreme Court.
Peterson was sentenced to death in 2005 after a San Mateo County jury found him guilty of killing his pregnant wife Laci.
The case garnered widespread attention beginning with Laci Peterson's disappearance on Dec. 24, 2002, and continuing through Scott Peterson's trial.
