CID Investigator Jeff Bilbo investigates a variety of different types of crimes with an emphasis on property.  Investigator Bilbo recently earned his Arson Investigator certificate to add to more than 30 years of Law Enforcement training he has gathered through multiple different agencies and states.  Investigator Bilbo has also attended the Oklahoma State Crime Scene Investigation and Homicide schools. Investigator Bilbo spent 2 years as the Holiday Island deputy when he was working patrol before being promoted to CID as an Investigator.  

Although all CID works their own cases individually, Investigators work together with a "team approach" when handling more serious or complicated case situations.  This approach is helpful in solving cases that may require an Investigators specialty training in dealing with a situation where he/she has more knowledge in a particular aspect of the crime.  We have found that being able to rely on each other's training or experience to be especially effective in solving felony crimes.  All Investigators have advanced training in interviews and interrogations.
