He says he has it but he keeps blowing me off with lame excuses.
You may file an incident report with the police. It will be up to the investigative detective, however, to decide whether criminal charges will be filed or not.
This is probably not an issue of criminal law. If you released the item to him voluntarily it is not a crime ... unless there is some reason to question the effectiveness of your consent. For example if he tricked you in the first place and never had any intention of fixing it, then it could be alleged that consent was obtained by fraud.... but that can be hard to prove unless he has done it to others.
This is probably best handled in small claims court but might not be worth the effort.
