Pennsylvania U.S. Senator Bob Casey was supposed to attend a fundraiser in Pittsburgh last Friday. Instead, the Scranton Democrat joined his Lehigh Valley Republican U.S. Senate colleague Pat Toomey for the somber memorial service of Christopher David Hill, a U.S. Marshal killed in Harrisburg while serving a warrant to a fugitive.

Hill was an 11-year veteran of the U.S. Marshals Service and an Army veteran. He died when executing a warrant for the arrest of Shayla Lynette Towles Pierce, who was wanted by the Harrisburg police for terroristic threat offenses, when 31-year-old Kevin Sturgis of Philadelphia opened fire on the officers from the second floor of her home.
