People v. Loker

Summary

The California Supreme Court affirmed Keith Thomas Loker’s convictions for multiple robberies, murders, attempted murder, assault, and burglary, as well as his judgment of death. The opinion addresses the admissibility of an autopsy photograph, jury instructions concerning flight, motive, and alternative theories of first degree murder, and the use of a psychiatric report during penalty-phase cross-examination. The court concluded that the asserted errors either lacked merit or were not prejudicial.

Holdings

1. The trial court properly admitted the autopsy photograph because it was relevant to the nature and placement of the fatal wounds, supported the prosecution's theory, and was not unduly prejudicial.
2. The challenged flight and motive instructions were proper, and the jury was not required to unanimously agree whether first degree murder rested on premeditation or felony murder.
3. The prosecutor and trial court committed several errors by using the Gaughan report as broad, suggestive, and sometimes irrelevant rebuttal, but the errors did not prejudice the penalty verdict.
4. The trial court did not violate defendant's constitutional right to present mitigating evidence by excluding marginal, speculative, cumulative, or irrelevant testimony concerning other family members and the religious community.
5. The trial court did not abuse its discretion by refusing to continue a protective order that would have restricted the prosecution from investigating defense witnesses and matters the defense intended to present.
6. The trial court properly excluded evidence that two victims had methamphetamine in their systems because it had negligible impeachment value and was not relevant to guilt, penalty, or victim-impact issues.
7. The prosecutor improperly injected personal experiences and beliefs into penalty-phase argument, but the error was harmless; other challenged argument was forfeited or not prejudicial.
8. The trial court was not required to instruct that mitigating factors need not be proved beyond a reasonable doubt or unanimously, and the instructions adequately informed the jury that sympathy and compassion could be considered.

Questions Presented

1. Whether an autopsy photograph of a murder victim was relevant and not unduly prejudicial.
2. Whether the flight, motive, and murder instructions were legally proper and whether the jury had to unanimously agree on a particular theory of first degree murder.
3. Whether the prosecutor's use of a psychiatric report during penalty-phase cross-examination exceeded the permissible scope of character rebuttal and prejudiced defendant.
4. Whether the trial court improperly limited mitigating evidence concerning defendant's upbringing and family history.
5. Whether the trial court abused its discretion by refusing a protective order restricting prosecutorial investigation of defense witnesses.
6. Whether toxicology evidence concerning the victims' methamphetamine use was relevant and admissible.
7. Whether evidence regarding Arizona plea negotiations was properly admitted.
8. Whether the prosecutor committed misconduct through improper cross-examination and penalty-phase argument.
9. Whether the trial court improperly excluded hearsay concerning a relative's criminal conduct during the penalty phase.
10. Whether the penalty-phase instructions adequately addressed mitigation, sympathy, and the burden applicable to mitigating factors.
