An app called CrimeDoor is the latest tool that some hope will help solve the murders of Delphi teens Libby German and Abby Williams.

The founders of CrimeDoor have made it possible for users to spend time walking through the crime scene using an augmented reality feature.

The feature allows people to see victims’ bodies and parts of the rooms or areas where crimes were committed.

The app features hundreds of unsolved cases, each one with its own profile, evidence and facts.

Founders Neil and Lauren Mandt told WISH-TV, sometimes seeing things in 3D can bring back memories that could help solve cold cases.
