A state appeals court panel this week upheld a Lancaster man’s conviction for strangling a woman who was sent to his home to repair a refrigerator.

The three-justice panel from California’s 2nd District Court of Appeal rejected the defense’s contention that there was insufficient evidence against Williams Franklin Hughes to support the jury’s finding of premeditation and deliberation involving the July 14, 2017, killing of Lyndi Fisher.

The appellate court justices found there was “overwhelming evidence’’ against Hughes, who was convicted in May 2019 of first-degree murder for the 36-year-old woman’s slaying at his home in the 43200 block of Doverwood Court.

“Evidence of motive further supported a finding of premeditation and deliberation, as the jury reasonably could have inferred that appellant was motivated to kill Fisher in retaliation for her perceived role in planting or retrieving a surveillance device in his refrigerator,’’ the 71-page ruling states.

The appellate court panel noted that the prosecution had suggested that Fisher may have rejected a sexual advance by Hughes, which might have motivated him to kill her.

Superior Court Judge Carlos Chung—who was called upon after jurors convicted Hughes to determine whether the defendant was sane or insane at the time of the killing—subsequently found that he was sane.

“Substantial evidence supported the trial court’s finding that appellant had failed to prove, by a preponderance of the evidence, that he had been incapable of understanding the wrongfulness of killing Fisher at the time he killed her,’’ the appellate court panel found.

Hughes first told detectives that an intruder pressed a gun against his eye and commanded him at gunpoint to take a walk. He said he complied by taking a 45-minute walk, and then spent two hours in the house before finding her body in the garage and claimed not to know what happened to her.

Hughes—who was arrested the day after the killing—is serving a 55-year-to-life sentence in state prison.
