CARSON CITY, Nev. (AP) _ A condemned killer committed suicide a day after Nevada's Supreme Court stayed his execution against his wishes, officials said Friday.

The body of Dennis L. Nogue, 26, of Walnut Creek, Calif., who hanged himself, was found in his locked single cell during a routine check late Thursday, said Nevada State Prison Warden Harol Whitley.

Nogue, condemned to die by injection March 4 for a March 1986 strangling, had told investigators he wanted the death penalty because he didn't want to spend the rest of his life in prison.

The high court Wednesday delayed the execution to determine whether Nogue properly waived his right to an appeal of his death sentence.

Nogue gave no indication of his plans, said Don Helling, an acting associate warden.

''All I can say is, look at what he said in court. He was serious about not wanting any delays in his execution,'' Helling said.

Nogue pleaded guilty in the slaying of Eric Henning, 19, also of Walnut Creek, who was beaten with a rock and strangled with a leather thong March 6 in a canyon area near Carson City.

Nogue said he killed Henning because Henning had informed on him in an apartment burglary. He also said Henning was armed with a gun and might have killed him.

Nogue also was convicted when he was a teen-ager for killing a fisherman on the Sacramento Delta.
