The Investigations Division is currently comprised of:

  • Eighteen detectives
  • Eleven school resource officers
  • One computer forensic specialist
  • Three forensic specialists
  • Two crime analysts
  • Two evidence technicians

We work together in conjunction with our patrol officers and the community in order to achieve our mission. There were many notable accomplishments and highlights in 2016.


The detective division is directed by one commander, one captain, and three Lieutenants. Two detectives specialize with investigating sensitive sex crimes, one detective works on Internet Crimes Against Children (ICAC) cases, one detective works on human trafficking and prostitution cases, and one detective specializes in child abuse cases. In addition, one detective is trained in Arson investigations. 

The remaining detective’s works cases including:

  • Burglaries
  • Frauds
  • Homicides
  • Robberies
  • Sexual Assaults
  • Thefts
  • Any other case that needs in depth follow up


Detectives receive training in death scene, overall crime scene and evidence collection, interview and interrogation as well as other training needed to successfully investigate crimes and refer cases to the District attorney.

Homicide Investigations

In 2016 the Detective Division investigated four homicides in Green Bay. The shooting death of Ricardo Gomez on April 2nd, the shooting death of Guleda Hirsi on September 11th, and the shooting death of Zachariah Boose on September 29th. Each of these homicide resulted in arrests with the suspects awaiting trial. These cases can take as long as two years to resolve. On November 22nd Patricia Hayden was killed by Joseph Kiefer who subsequently killed himself.

Technology & Transitions

We doubled the size of the computer cell phone analysis lab last year as this is becoming an increasingly important part of our investigation work. Keeping up with technology will be an ongoing challenge. Also in 2016 we transitioned from sworn to civilian in computer forensic position. This allows the police department to put an additional officer on the street while hiring a trained civilian that has studied this field in college.

In 2016 we also began the transition from sworn to civilian in the crime scene forensic position (CSI). All new CSI’s require a bachelor’s degree in forensics. This again allows the police department to put more officers on the street while hiring highly trained people to process crime scenes and evidence.


In 2017 we are working with other Brown County Law Enforcement agencies to create a county wide response protocol missing children. The Child Abduction Response Team (CART) is designed to put resources quickly into an area where there is a missing or abducted child.

The Green Bay police department has partnered with the Golden House to apply for a grant that will help train all officers on conducting Lethality Assessments during domestic violence investigations. The Green Bay police department refers more than 500 domestic violence cases to the district attorney’s office annually. The goal of the lethality assessments is to prevent domestic violence related homicides.


Many crimes in Green Bay are crimes of opportunity. Citizens can help deter crime by keeping valuables in vehicles out of sight and locking car doors. Also remember to secure bicycles and keep homes and garages locked.
