The Case of the Dead Brother

John Schmidt was found dead in his apartment. The cause of death appeared to be by a single gunshot wound to the head. A gun lay by the side of the apparent suicide.
“It’s a tragedy,” Davis told Moreno. “I guess we’ll have to notify his next of kin.”
James Schmidt broke down in tears when he heard the news.
“I can’t believe it ….,” he cried. “I just talked to him yesterday. He seemed to have so much to live for….”
“He gave you no indication that he might do this?” Moreno asked.
“No, why, no,” the man answered. “He said that he had some money problems, but that he’d get through them. If I had just known about how depressed he was, I could have helped him. Oh, if only I had helped him,” he whined.
Detective Davis glanced at some photographs in an album on a coffee table. He saw a picture of a man writing happily on a notepad.
“Is this a picture of him?” He asked.
James looked at it.
“Yes, it is,” he replied. “Poor John. He loved to write, but unfortunately, he didn’t make too much money at it. Perhaps I can use some of my wealth to publish his stuff as a memorial to his devotion.”
“We deeply regret your loss,” Moreno said.
“Yes, please be in touch if we can be of any further assistance,” Davis added as he handed James his card.
“Thank you for you concern,” the man replied. “I don’t know how, but somehow I’ll handle this.” He wrote down some words on a piece of paper. “There’s so much to do. I have to write things down in order to remember them. I guess I just need some time alone.”
“We understand,” Moreno said as the detectives went through the door.
“What do you think?” He asked Davis as the two were walking toward their car.
“I’ve got the fingerprints of both,” his partner replied. “If what I believe is true, we should make an arrest very soon.”

WHY DID DAVIS SAY THIS?

THE ANSWER
Davis suspected John of murdering James and then assuming his identity. The two were twin brothers! He learned from the picture that John was left handed and yet the man in his apartment had appeared to be right handed by the position of his gun. When he saw “James” using his left hand to write, his suspicions were aroused. Further evidence collected proved that his theory was right and John was soon arrested.
