What is the test for habeas corpus relief from a conviction for aggravated robbery?

Because Pounds is applying for habeas corpus relief from a state conviction, he can succeed with his evidentiary challenge only by showing that no rational trier of fact could have found the required nexus beyond a reasonable doubt. See Jackson v. Virginia, 443 U.S. 307, 324 (1979). We conclude that Pounds has failed to make that showing. The statute broadly defines the types of relationships an aggravating robbery need bear to the underlying murder; it even includes murders committed in flight from a robbery. See Wash.Rev.Code Ann. Sec. 10.95.020(9)(a) (Supp.1988). The evidence showed that Pounds robbed the victim of his wallet, a gold chain, and other belongings at gunpoint while they were riding in a car to the site of the murder. Pounds kept the gun aimed at the victim from the time of the robbery until his death. Based on such evidence a rational trier of fact could find the required nexus between the robbery and the murder.
