Major Crimes Unit

Headed up by Detective Sgt. Linda Mixon, the Major Crimes Unit encompasses three different areas of investigation including crimes against women and children - primarily sexual abuse and child abuse, Homicide Investigations and Victim Advocates.

The Major Crimes Unit investigates homicides, sex crimes, computer crimes, missing juveniles, child pornography and related crimes, and includes the agency’s victim advocates. The Major Crimes unit also maintains records on registered sex offenders and conducts quarterly address verifications on offenders living in Monroe County.

This highly trained unit conducts investigations throughout Monroe County working closely with districts and with the public. The unit consists of five detectives, four victim advocates and one supervisor, Detective Sergeant Linda Mixon.

The unit investigators are certified with Internet Crimes Against Children (ICAC), the National Child Abduction Response Team (CART), Department of Children and Families, Customs and Border Protection, Immigration and Customs Enforcement, and the Florida Department of Law Enforcement (FDLE). They work closely with these and other agencies on many of their investigations.

When they aren’t working active investigations, Major Crimes investigators are involved with the homicide cold case squad. This squad also consists of retired law enforcement officers and FDLE investigators. The cold case squad continues to examine older homicide investigations, as new technology - and thus new information - becomes available.

Victim Advocates: There are four victim advocates working for the Monroe County Sheriff’s Office. The advocates serve all of Monroe County and the city of Key West. The advocates assist victims of crimes committed in the county, in particular the victims of violent crimes. Advocates are available throughout the county at all times.

Some of the funding for the advocates comes from a grant from the Office of the Attorney General. Victim Advocates are an integral part of the criminal justice process, especially where arrests have been made. They are responsible for contact with victims and they assist during the trial process help to gain successful prosecution of defendants. Click here for more information about this program.
