Over half a century ago, Frisco lost a guardian in blue in a harrowing incident that resonates through the years. On January 29, the Frisco Police Department remembered Officer Joe Murphy, who became the department’s first line-of-duty fatality when he perished in a vehicle crash back in 1968. Joe Murphy, not just a dedicated officer, but also a sibling of the decorated military icon Audie Murphy, left behind a legacy of service for the city of Frisco, according to the Frisco Police Department.
