The Soroptimist Three Rivers Club will sponsor the third annual Walk to Stop Child Trafficking Now on Sunday.

State Sen. Jerome Delvin (R-Richland) will kick off the walk, which begins at noon in Columbia Point Park in Richland.

Stop Child Trafficking Now is a nonprofit dedicated to fighting the demand for child sex trafficking. Last year, more 40 communities around the world participated and raised $750,000.

The event is free and open to the public. The suggested fundraising minimum is $100. To register, go to events.sctnow.org/Richland.
