305 A.3d 1068
Pa. Super. Ct.2023Background
- On April 3, 2016, Yaw forced entry into an apartment armed with a handgun and metal baseball bat; the occupant (victim) was beaten in the head, later died of blunt-force head trauma.
- Police recovered a .22 casing; witnesses (roommate, roommate’s girlfriend, and the female acquaintance) identified Yaw in photo arrays and at trial; the female acquaintance later recanted an initial claim of rape but then gave consistent statements implicating Yaw and helped locate the bat.
- Yaw was convicted by a jury of first‑degree murder, burglary, and kidnapping; sentenced to life plus consecutive terms; direct appeal affirmed and judgment became final July 19, 2019.
- Yaw filed a PCRA petition claiming trial counsel ineffectiveness for failing to investigate/present a diminished‑capacity defense based on traumatic brain injury (TBI), mental-health history, and childhood abuse.
- Trial counsel had retained Dr. Frank Dattilio (forensic/clinical psychologist) and Dr. Carol Armstrong (neuropsychologist) for evaluation/mitigation; neither concluded Yaw lacked the capacity to form specific intent.
- At the PCRA hearing Yaw presented Dr. Jethro Toomer, who opined Yaw could not form specific intent due to TBI and related impairments; the PCRA court denied relief and the Superior Court affirmed, holding counsel’s strategy was reasonable and no prejudice shown.
Issues
| Issue | Yaw's Argument | Commonwealth/Trial Counsel's Argument | Held |
|---|---|---|---|
| Whether trial counsel was ineffective for failing to investigate and present a diminished‑capacity defense at guilt phase | Yaw: counsel failed to consult the right expert and did not pursue diminished capacity despite TBI, lifelong mental illness, and abuse, which would negate specific intent | Counsel: relied on two experts who found no diminished capacity; pursued provocation/voluntary‑manslaughter/third‑degree strategy; telephone calls and other evidence showed planning and ability to form intent; no prejudice | Affirmed denial of PCRA: no arguable merit to claim; counsel had reasonable basis; no prejudice shown |
