Apparant Suicide

The next case that I had occurred a few before the terrible accident. I work as an EMT and as Nodnol is a small town, we as the citizens hold two jobs to cover the entire town.  Often, people like me end up working double shifts. Sometimes back to back. Being a small town cases usually would be unrelated and small and far in between. The cases that continued to appear on my desk began to tell a different story. They were unrelated in the beginning, but then they began to link together.
The call came in early in the morning, a suicide in the upper link apartments, a white male, late 30's, gunshot wound to the head. Suicide was the deemed report. However, one smart person in the room said: "Wheres the gun?" This shot the whole case right open and that is why it's on my desk. 
So the stats of the case included: A room that was locked from the inside, suicide shot to the head while sitting in a chair, gunshot residue on the right hand (man was a right-hand man) and a missing gun. This was the interesting part, a missing gun.  How can someone kill themselves without a gun? The next thought we had was his wife, but his wife was out of town on business, or so we thought. Turned out the trip was bogus and she had only formed the trip so she could run of to Vegas with, get this... her sister. Fortunately the video cameras were able to back up her story, with her sister next to her the whole time. Story backed up. First lead died, as well as the dear beloved wife of the man had fainted when she heard that her husband had died, due to a 'gun shot to the head'.  We could have said suicide, but we needed a gun to say that he did committed suicide.  I ruled her off of the suspect list when I saw her reaction to her husbands death, she denied it, called me a liar, tried to call him herself and when the phone in the evidence bag started to ring did she finally believe me. The poor dear. She came in once a week after that, asking about her husbands killer, she wanted to know and she looked as if with every moment that went by without her husbands killer surfacing she died. The poor thing.
This was the first case, but I hadn't realized how close it was to the case on the woman nicknamed 'Angel' but the police crew of Nodnol. In the deconstruction of the car that killed 'Angels' husband there was a gun discovered, an exact match to the bullet that killed the man in the apartment. We had a few questions for 'Angel' when she woke up, if she ever woke up from the coma that she was currently obsorbed in.
