PITTSBURGH (KDKA) – A man charged with stabbing a step-brother to death will not be required to testify in a civil case brought by his parents against Western Psychiatric Institute and Clinic.

Allegheny County Judge Michael Della Vecchia quashed a subpoena that would have required Troy Hill Jr. to testify.

Hill is accused of stabbing his two 11-year-old half-brothers back in 2007 in their Penn Hills home. One of them died.

Hill’s parents filed a lawsuit against Western Psych claiming its professionals should have done a better job of warning them about his mental illness. Their suit claims wrongful death and negligence.

Hill was ruled incompetent to stand trial shortly after the stabbings and has yet to go to trial in criminal court.

The judge had concerns about his rights against self-incrimination since his criminal trial is still pending.

Jury selection in the civil case has begun. Testimony is expected to begin tomorrow.
