NEW KENSINGTON, PA. (AP) — The father of the man sentenced to death for the murder of New Kensington police officer Brian Shaw was convicted Wednesday for the intimidation and retaliation of a potential witness at his son’s trial last year. Gregory Baucum was convicted on two misdemeanor counts Wednesday but acquitted of a felony charge. The former Arnold resident faces up to four years in state prison when he’s sentenced later this year. Authorities have said Baucum threatened the witness on social media, labeled her a snitch and published details online of her cooperation with law enforcement.
