The Washington County Sheriff’s Office Investigative Division primarily investigates felony level crimes in all areas that utilize the Sheriff’s Office as their law enforcement agency, while also providing assistance to partnering agencies throughout Washington County.
The Washington County Sheriff’s Office strives to provide high-quality law enforcement services to the public we serve. While each crime that is reported is evaluated thoroughly for evidence and solvability factors, not every crime reported is assigned to a detective. Detectives working in the Investigations Division are assigned cases through a variety of means; including calls from patrol, direct calls to scenes, referrals from other law enforcement agencies or community services, and through assignment by the Detective Sergeant or Division Commander.
The General Investigative Unit primarily investigates felony level crimes in all areas that utilize the Sheriff’s Office as their law enforcement agency. This unit is also available to assist all local law enforcement agencies throughout Washington County. Some types of crimes that are investigated are homicides, assaults, burglaries and thefts.
Those investigators assigned to the Computer Forensics work a wide variety of cases. They are called upon to assist in drug investigations, homicides and fraud cases. Also, they are responsible to investigate child pornography cases. The Washington County Sheriff’s Office Computer Forensics Unit works in partnership with the Minnesota Internet Crimes Against Children (ICAC) to investigate and bring charges against those that perpetrate these crimes. This unit is also responsible to assist with investigations involving many different types of multi-media.
The most common forms we encounter and investigate in Washington County are sex trafficking and labor trafficking. We’ll start with a couple of definitions.
Sex Trafficking is the recruitment, harboring, transportation, provision, or obtaining of a person for the purpose of a commercial sex act, in which the commercial sex act is induced by force, fraud, coercion, or in which the person induced to perform such act has not attained 18 years of age.
Labor Trafficking is the recruitment, harboring, transporting, provision, or obtaining of a person for labor or services, through the use of force, fraud, or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage, or slavery.
What are some of the ways traffickers control their victims?
One way is through debt bondage. The trafficker may have paid for clothes, transportation or housing for the victim. They then hold the victim financially obligated with undefined or ever increasing debt payment.
Traffickers make sure to isolate their victims from the public, and from family and friends.
Traffickers often confiscate the passports, visas or identification documentation until the "debt" is paid. They will threaten the victim with deportation or imprisonment to buy their silence.
Victims may remain silent due to threats of violence towards them, or their family or friends. Traffickers will also use shame by threatening to expose the victim on the internet.
Traffickers will almost always control the victims time, money, personal affects so victims are completely dependent.
How Do You Identify a Trafficking Victim?
