Just a moment later, Chris called 911 to report that his wife had died on the bed in the bedroom.

Military police from the Fort Lewis military base, Washington state, arrived and found that Dorothy Davis, Chris’s wife, was lying dead on the bed, holding a pistol in her right hand.

Police saw no signs of anyone using force to break in, or that any arguments or struggles occurred in the bedroom.

Working with the police, Corporal Chris testified that he went out to drink beer with his teammates that night.

In three handwritten envelopes by the bed, there were two letters addressed to Chris, which read, `Dear, you once said it was the coward’s way out. If so, you are the coward for not looking.`

Three envelopes near the body.

The third letter was sent to Dorothy’s sister with the content `When you read this letter, I will be no more. I don’t know what to do anymore. I’m sorry.`

All three letters had Dorothy’s fingerprints on them.

The police saw that Dorothy’s hand was holding the gun very firmly, consistent with the fact that the muscles immediately become stiff if the deceased is very active or is under severe stress right before death.

Through surgery, the specialist discovered that the bullet wound in the temple was a gunshot wound, consistent with self-inflicted injuries.

The evidence all points to suicide.

Although unusual, the police still believed the expert’s conclusion and believed that Chris’s adultery was not evidence that he killed his wife, but only contributed to making Dorothy’s depression and suicidal thoughts more serious.

One year after Dorothy’s death, the female witness who sat at the same table as Chris that night came forward to provide testimony, causing the police to reopen the investigation.

With this detail, the military investigator reviewed the video recording of the scene and discovered a shirt similar to the witness’s description hanging on the bedroom doorknob.

Chris’s shirt was hung neatly on the doorknob.

To verify whether Chris had enough time to return home, kill his wife and then return to the bar, the police experimented with traveling between two locations.

Continuing to investigate further, the police discovered that about three years ago, Dorothy accidentally died once while staying with her husband at the Fort Polk military base, Louisiana.

After the fire, the investigator determined that for some reason, the house’s fire alarm did not sound, and the cause of the fire was due to a short circuit in the television.

At this time, the police continued to notice that in the photo, Dorothy’s hand when she died was only holding the butt of the gun, her index finger was not on the trigger, so why could the victim pull the trigger herself?

If Chris committed the crime, the police believe that the `suicide note` attributed to Dorothy was in fact forged by Chris.

Because people about to commit suicide often sweat a lot when writing suicide notes, forensic technicians use ninhydrine – a chemical that reacts with amino acids in human sweat.

Dorothy’s index finger was not on the trigger.

At this moment, the police were informed by Dorothy’s sister that the details had never been published.

Next, the police noticed that the envelope was sealed with saliva.

Because the body had been cremated, the technician reconstructed Dorothy’s DNA through her grandparents and two children.

Through examination, the expert concluded that the saliva sample used to seal the envelope was Chris’s.

With the above evidence, Chris was arrested and charged with Murder.

Prosecutors alleged that three years earlier, Chris had intentionally set a fire and turned off the alarm to kill his wife but failed.

On the evening of March 13, 1991, Chris went to a bar with colleagues to create an alibi.

Finally, Chris was convicted of Murder by a military court in 1993, was kicked out of the army and received a life sentence without parole.
