As a "career detective," Shannon was the lead investigator in over 5,000 cases, including unattended deaths, homicides, and the successful prosecution of a 1994 rape cold case that resulted in a 64-year sentence. Shannon's unparalleled commitment to the development and demonstration of best practices for working with victims of sexual assault, child abuse, and domestic violence led to her recognition as a subject matter expert throughout the metro area. 

Following retirement in 2021, Shannon pursued an opportunity in the academic world, as a senior-level Title IX investigator for a large university. However, Shannon was soon drawn back to law enforcement, joining the Johnson County District Attorney's Office in Olathe, Kansas as a criminal investigator in 2022. Shannon is an investigator with the Johnson County Officer Involved Critical Incident Investigative Team (OICIIT) and she is a member of the Johnson County Domestic Violence Multi-Disciplinary Team. She is the longest standing member of the Johnson County Sexual Assault Response Team and the current Chair elect.

As an instructor, Shannon provides trauma-informed sexual assault and domestic violence training for her law enforcement peers, recruits, prosecutors, medical providers, and other stakeholders. As a public speaker, Shannon presents at law enforcement conferences on a regional and national level and she has testified before the Senate and House Judiciary Committees at the State Capital. She represents District 1 as a Governor elect for the Kansas Peace Officers Association (KPOA). She is an avid photographer in her free time.
