Commonwealth v. Shu Feng Hsu

Summary

The Massachusetts Supreme Judicial Court affirmed the conviction of Shu Feng Hsu for involuntary manslaughter, holding that the evidence was sufficient to support the verdict and that the trial judge did not abuse his discretion by admitting expert testimony that the infant’s injuries were "consistent with" abusive head trauma. The court reasoned that a rational fact‑finder could infer the defendant’s reckless conduct and that the expert testimony met the Daubert‑Lanigan reliability requirements while being properly limited to avoid prejudice.
