Police found the body of a computer technician in front of his computer, with a belly wound. There was a possibility of the victim bleeding to death after being stabbed with a sharp object. There were no signs of damage on the windows or doors, which indicated that the killer was someone close to the victim. The dead body was found holding the keyboard and mouse. The monitor displayed the explorer and command prompt. On the user folder of his computer (Windows 8), police found one image file with the name img.gif. They also found blood on the following keyboard keys:
Enter Shift Space Alt F7 = / . A B C E F G I L M O P R U Y
The bold keys indicates that the key has more blood than others, and here is the image (img.gif):
The questions is, who killed the technician?
- the layout of the keyboard was QWERTY
- the command prompt was open, but without any text; apparently the victim just deleted the history by Alt+F7
- there is a possibility that the victim or someone else deleted some files
- the culprit's name is on the list
- the keys are not in sequence
