11 Del. C. § 8532: Original complaint.

A missing person complaint may be made to any county, town, city or state law-enforcement agency or any other appropriate state agency. The law-enforcement agency having primary jurisdiction over the verified location where a missing person was last seen shall be responsible for receiving a missing person complaint and initiating the investigation. If the location where the missing person was last seen cannot be verified, the law-enforcement agency having primary jurisdiction over the missing person’s last known place of residence shall be responsible for receiving a missing person complaint and initiating the investigation. Such complaint shall state the age of the missing person. When an agency has received a missing person complaint, such agency shall immediately disseminate all known facts concerning the missing person to all county and state law-enforcement agencies, and to any other law-enforcement agency which may be appropriate. A new missing person complaint shall have high priority.
