WASECA, Minn. — An effort to sell T-shirts for a Minnesota police officer injured in a shooting has raised nearly $16,000, supporters said.

Waseca Officer Arik Matson was shot in the head in an exchange of gunfire in January. A group of people representing various businesses on Wednesday presented Matson's wife, Megan, with the money gained from the sale of about 1,200 T-shirts, the Alberta Lea Tribune reported.

Lori Nelson and her son, Trent, run 407Designz in Alden. Lori Nelson said that after her son designed the shirt, they posted it on Facebook, and the effort grew rapidly from there. The design includes the words “praying for Arik.”

Megan Matson said every penny counts toward her husband's recovery and he is making steady progress.

“The prayers are definitely working through him,” she said, noting he has been in good spirits.

The suspect in the shooting, Tyler Janovsky, is charged with with three counts of attempted first-degree murder of a peace officer.
