GENERAL REMINDER TO ALL VOLUNTEERS AIDING IN THE SEARCH OF MISSING PERSONS. We have come across a few cases where an individual will create a post search for a missing relative, and the individual posting does not have good intentions. For example, someone claims to be searching for a long lost sister, but doesn’t know their last name. There are criminals who monitor posts to find new victims. Please be careful when providing information you may come across in investigation efforts to help family members. Be sure you vet the person who has authored the post. Another example may be a spouse who has willingly escaped an abusive marriage and the abuser is out searching for the spouse. We all need to take a few extra steps in responding to pleas for help, to ensure we do NO harm.

Dear Missing Person page administrators,
If you have contact with family members who have stalled missing or murdered cases in their family, please feel free to let them know our services are available at no cost or fees, should they need assistance with search effort strategies, with new and evolving investigative tools and techniques or information/knowledge regarding typical law enforcement practices, we are happy to share any working knowledge to aid them in their search efforts. They may reach us at our Armchair Detectives, Missing and Murdered page, or may contact myself at [email protected]. If we can provide assistance, we are retired volunteers and happy to share our working knowledge and expertise. Thank you.

Dear Friends of Missing persons,
I have just finished working two cases with families; one of a missing father, and one of an assistant DA found deceased in her home. Both cases were resolved differently, but successfully. I am looking to advocate for a few more families to provide counsel in investigative techniques the loved ones can legally and ethically do to support law enforcement in the search for their missing family member, and in generating new ideas and techniques to assist in resolving cold cases.
Our requirements at Armchair Detectives are that we only work with a family member; we do not do investigative work ourselves, we counsel you in how to work and question and provide knowledge to your assigned L.E. Investigators. It’s not as easy as it looks. Often a family member doesn’t know what questions to ask. Or they have access to information that they are completely unaware of. We do not detract from investigations, we simply provide information that may help family members in their own search.
Please reach out here, on this page via messaging, if you have a loved one, or know of a loved one who could use assistance in working more cohesively with L.E. to find their missing family, or find out what happened to a family member. We do not charge any fees, or accept tips, monetary benefits of any kind. We simply are available to act as assistance with families during their own search efforts or in working with their assigned Investigator. We are now open to accept three new cases. Thank you, Diana Diehl

I have established a submittal form for all families who wish to have their missing person potentially matched to unidentified dead remains through out the USA. We will provide a family member with a report showing possible matches to provide the LE Investigator handling their case. This is helpful in older cold cases, where time has been sufficient to measure against found remains. This is strictly free of all charges and may help families seek to exclude unidentified remains from medical examiner cases. To all families with missing family members, it is critical to submit DNA comparisons to be sampled against the DNA of remains. Your medical doctor or LE Investigator can explain how to go about this process. Each report will explain why each unidentified case is being submitted to you as a potential match. Please submit requests with each missing persons case information to [email protected]. I am happy to provide a list of all available potential matches, and the logic behind each potential case, so that families can better work with their LE Agencies to resolve cold cases more timely.

I have had to unfollow several politically based commenters. This site is strictly for missing and/or murdered unsolved cases. Do not follow this page unless you are posting an unsolved murder case or a missing persons case. We are trying to disseminate as much information as possible on unsolved cases, not your political commentary. Thank you.
