The Sun Prairie High School gym was packed, alongside Barr's family, his widow Abby and two young children were hundreds of community members and first responders, some from as far as Lincoln Nebraska.
Throughout the service we were reminded his family was his sweet spot, everyone in the community loved that about him.
His death even brought people who didn't know Cpt. Barr to the memorial service
"It's such a tragedy that we're here to come together for him and the family," said Karen Kuemmel, who lives in Sun Prairie.
In October his name will go on the State Fallen Firefighters’ Memorial in Wisconsin Rapids.
