You answer is unclear as to what you want to do. Do you want to sue the person that kidnapped you? You weren't the victim of a murder - unless you're asking the question from beyond. You should contact the police again if you're concerned for your life or the local prosecutor's office. They may be able to help.
This is not legal advice nor does it create an attorney-client relationship. This is for education and informational purposes only. It is always recommended that you contact an attorney with any concerns as each individual case is unique.
In addition to what Attorney Wills suggested, you can also file for a restraining order against this person.

There is no confidentiality online. Volunteering to answer this question does not create an attorney-client relationship. The likelihood of a positive outcome is increased with the help of an experienced criminal litigator. Seek out an experienced criminal litigator for a free consultation.

Sorry but you don't get to "open" a criminal case. Only the DA can file charges after reviewing the appropriate police report. The fact that the detective is not doing anything should tell you something. Either the facts don't support your claim or he is doing further investigation. As for a civil action, I suggest seeking a restraining order against the person who "kidnapped" you because I doubt a civil action will go anywhere. But you can always talk to a civil attorney and explain your case.
