A Sun Prairie post office will be renamed in honor of fallen firefighter Capt. Cory Barr. The Senate passed bipartisan legislation to make the change Wednesday. Barr died last July while responding to a gas leak in downtown Sun Prairie. Barr is credited with evacuating more than 100 people from the affected area before an explosion erupted. He was the only casualty of the explosion. “Capt. Cory Barr paid the ultimate sacrifice to protect Sun Prairie residents and save lives. Capt. Barr is a hero and I am proud that we are honoring his public service and commitment to protecting others by officially designating the Sun Prairie building in his name,” said Wis. Sen. Tammy Baldwin, who introduced the legislation along with Sen. Ron Johnson.
