Two years after two Delphi teenagers were murdered while hiking on the Delphi Historic Trails, their families are honoring their memory.

The families of Abby Williams and Libby German will hold a food drive at Delphi United Methodist Church on Feb. 13, the anniversary of the day the girls went missing in 2017.

The public is invited to drop non-perishable human and pet food at the church, 1796 U.S. 421, between 5 and 7 p.m. that day.

For those who can't make it to Delphi, the families say they're encouraging people to donate in Abby and Libby's names to a food pantry in their hometowns.

Also, if you're unable to take a donation to the church, the families' fund for softball facilities in their daughters' names is still accepting donations. The Libby and Abby Softball park is expected to have three ball diamonds along Indiana 25.

Work began on the project last year, but donations made to the project will go towards "the development, enhancement and maintenance" of new and existing softball facilities in Delphi.
