The person who entered the information into NaMUS is listed as the Case Owner in the Contact section. In this case, that is Claudette Hysjulien, Detective Sergeant for the Chaffee County Sheriff's Office. The Case Owner may also designate an alternate contact, which Sgt. Hysjulien has done. She listed Special Agent Kevin Koback of the CBI.
Normally, if the Case Owner retires or moves on, a new contact within the LE office that originated it will be named as a Case Contributor, but the original listing for case owner will remain. The NaMUS case number is 4925.
In answer to the actual question, the information on NaMUS all originated with Detective Sergeant C. Hysjulien, who has the case responsibility within the CCSO. IMO
