A concert was held in Cedar Rapids Sunday night to help the family of a police officer who’s recovering from an assault. The event included a surprise guest. Several organizations have held fundraisers for officer Tim Davis, who suffered a serious head injury in March.

The concert on Sunday was billed as "The Final Fundraiser" by Cedar Rapids Police Protective Association and the Cedar Rapids Police Auxiliary. Hundreds of people attended, including officer Davis. It was his first public appearance since the assault. Davis did not address the crowd and his family did not want to comment, but told reporters they’re grateful for all the help.

Cedar Rapids police officer Rod Schulte believes the incident has actually strengthened the community and the department. "It’s a tight knit group now," Shulte said. "Everybody’s willing to work with everyone else to try and curtail what’s going on in the city."

Seventeen-year-old Jose Rockiett is charged in the assault on Davis. Sunday’s concert raised nearly $8,000.
