Offender Prelog Web Program

In an effort to increase efficiency and productivity, the KBI Forensic Science Laboratory has an Offender Prelog Web Program available to our customers for DNA submissions to the DNA Databank. It is a web-based program for logging offender DNA sample collections which are required by Kansas law, K.S.A. 21-2511. The program can be accessed through the KCJIS portal:
