Gina Bos

Gina Bos disappeared near Duggan's Pub in downtown Lincoln on Oct. 17, 2000, at the end of open mic night. She put her guitar in her trunk and then vanished.

More than 100 tips have been investigated, Sgt. Ken Koziol with the Lincoln Police Department said in 2016. The high-profile case has an electronic file thousands of pages long, among the largest Koziol can remember in his then-38 years on the force.

The cold case is classified as a missing persons case, although it’s highly unlikely Bos, 40 when she disappeared, is alive. Koziol declined to detail the leads the department has chased, citing the open investigation.

Bos was a middle child in a large, close-knit family; she was waiting for a Habitat for Humanity house and had begun a new job when she vanished.

Bos’ sister, Jannel Rap, became the family’s spokeswoman early in the search. She started the Squeaky Wheel Tour, traveling the country performing and bringing attention to Gina and others who are missing in the cities she visited. She also started 411 GINA, a website with a hotline for tips about her sister’s whereabouts.

Said Koziol: “Someone knows what happened to her. Hopefully one day they will finally find it in their soul to come forward.”
