Missing Person and Locate Person Investigations

ICS of Washington accepts missing persons cases in Washington, even if no crime has been committed, or if the police have already conducted an investigation.  Traditionally, missing persons cases are handled by local law enforcement and the FBI, in collaboration with the AMBER Alert system, but often a private investigator will be called in to assist or take over a case when these agencies are unable to help. In the state of Washington it is not illegal for children to run away, and so the local police will not be able to help.  Private investigators are not bound by the same jurisdictions and regulations as police, which means that private investigators can find runaways in Washington. Many lost person cases in Washington simply fall outside the scope of criminal investigations, for instance, if you’re searching for a friend or family member with whom you have lost contact. If you have an unsolved missing person case, or need to locate a lost person in Washington, ICS can help.
