Cranberry Township Cpl. Dan Hahn returned to light duty in December 2012, about 22 months after he hopped over a jersey barrier while chasing 22-year-old Thomas Booth back on Feb. 14, 2011.
Neither man apparently realized they were on an overpass above Interstate 79.
Booth died. Hahn broke his back, sternum, ribs, and had a concussion.
The municipality plans to promote the 50-year-old Hahn to sergeant before he retires Jan. 31.
