The People v. Mercado, 156 Cal.Rptr.3d 804

Mercado was convicted of second-degree murder and attempted murder with enhancements for inflicting great bodily injury and injuring a pregnant woman; she was sentenced to 32 years to life.
Davis, eight months pregnant, was struck by Mercado’s Range Rover during a dispute over Davis’s pregnancy and car keys, resulting in Davis’s injury and the baby’s death.
Waller, Davis’s former partner, testified to Mercado’s jealousy and threats toward Davis; he indicated Mercado intended to kill Davis.
Independent eyewitnesses Cotton and Gilyard observed Mercado hit Davis with the car; their testimony supported that the killing was intentional.
Medical evidence showed the baby’s death was due to blunt force trauma, with the autopsy labeling the death a homicide based on the circumstances.
Mercado challenged aspects of trial including jury instruction handling, effectiveness of counsel for failure to obtain a psychological report, confrontation-clause issues from medical examiner testimony, cumulative error, and sentencing enhancements.]
The court ultimately affirmed the judgment as modified and denied the related habeas petition, addressing Williams v. Illinois implications on testimonial evidence and other authorities.]
The court struck a three-year enhancement under § 12022.7 and ordered an amended abstract of judgment reflecting sentencing modifications.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did the trial court err in answering the jury's deliberation question about CALCRIM 520/570 elements?	People argues the court shifted burdens by requiring all three elements.	Mercado contends the response was misread as burden-shifting.	No error; answer correctly addressed conjunctive elements for both instructions.
Was Mercado deprived of effective assistance by not obtaining Dr. Baca's report in time?	Mercado asserts failure to use the report prejudiced her heat-of-passion defense.	Mercado's evidence did not establish the objective provocation element; report would not have changed outcome.	No ineffective assistance; prejudice not shown.
Did Dr. Chinwah’s testimony about the baby’s manner of death violate the Confrontation Clause?	Mercado claims reliance on coroner’s investigator statements was testimonial.	Statements were not testimonial under Williams/Dungo; proper basis for expert opinion.	No Crawford violation; any error harmless.
Is there merit to Mercado's cumulative-error claim?	Mercado asserts multiple errors collectively harmed trial.	Only one or no prejudicial errors present.	Rejected; no cumulative error.
Was there sentencing error in the enhancements for the Davis injury and fetus-related harm?	The concurrent enhancements improperly punished the same injury.	Only the greatest enhancement applies under § 1170.1(g).	Three-year § 12022.7 enhancement stricken; judgment affirmed as modified.
