Can a civilian solve cold cases?

According to the National Institute of Justice, America is in a cold-case crisis. Because of this, law enforcement agencies and resources are sparsely saturated. The FBI's 2017 Uniform Crime Report says investigators solved 60% of homicides that year. That leaves over 250,000 unsolved homicides, including a backlog.
What is the difference between murder, manslaughter and manslaughter?
Rules to be observed –Are private investigations legal?
Private investigations are legal if you obey the law. However, during an investigation, you are breaking the law if you do any of the following:
- Impersonating a Police Officer: The law does not allow private investigators to wear a badge, wear a uniform, or impersonate a police officer in any way.
- You Cannot Legally Arrest a Suspect: In some states, the law allows private individuals to make a private arrest if the suspect has committed a crime. However, doing so can result in a lawsuit or unlawful detention, so it's safer to call law enforcement. In other words, don't take the law into your own hands.
- Trespassing: Trespassing on private property is a crime, which means private investigators cannot legally break into another person's home or property.
- Invasion of privacy: The law does not allow private investigators to eavesdrop on or invade another person's privacy in any way.
If you have enough evidence to warrant a search or arrest of a suspect, we encourage you to contact law enforcement.
Can civilians investigate cold cases?

How do I find older cold case files?

According to the courts, murders or cases that occurred before 1999 are on paper. You can therefore access it at NARA. What is NARA?
NARA stands for National Archives and Records Administration. As the name suggests, NARA is the nation's records keeper, preserving all materials and documents created by the federal government of the United States. Note that NARA only permanently retains between one and three percent of the documents it deems important. This means that older records of resolved cases may be deleted.
How do you request access to NARA records?

Access to the recordings is by appointment only, i. H. You must have a virtual consultation before visiting the archive in person. There are also some restrictions because of the corona virus. It is therefore important to request access before visiting.

What if the court seals the record?
Juvenile records, subpoenas or warrants, documents containing jury information, and records that may reveal defense strategies of court-appointed attorneys are not public documents. Remember, the court has the power to seal these documents to protect victims, whistleblowers, and information that could interfere with ongoing criminal investigations or the defendant's rights to due process.
For example, if a witness is cooperating with authorities, the court may seal the whistleblower's hearing transcripts and criminal proceedings documents to protect the witness from possible retaliation.
In short, you need a court order to access sealed files.

How do detectives solve cold cases?
Investigators and detectives use the above resources to solve unsolved cases.
The question is how?
Find errors in the investigations and who conducted the investigations

A case can remain unsolved for decades due to investigative errors, corruption, lack of sufficient evidence, lost or destroyed evidence, the victim's lifestyle or social status, poor police work, the accused's financial situation, and many other reasons.
What you have to do is check everything. These are documents, videos and related material to build a narrative. The idea is to identify discrepancies in the narratives and then look for answers. For example, if the victim was a prostitute or a gangster, investigators may lack the motivation to solve the case.
What about the investigator?
Did the person have an interest in the outcome of the case? Was the investigator financially or otherwise motivated not to bring the investigator to justice?
If you look through the case files and records, you may find evidence that others have not seen.
Collect data from correctional facilities
If the suspect is in prison, you can ask to interview the person or someone who shared a cell with the suspect. But limit what you reveal about yourself as you may compromise your security.
