It's Elementary #3

Rules:

Normal sudoku rules apply.

You are called to an office where the boss has been found dead and four employees denying their involvement. You ask them what they were doing at the time of the murder, and they give the following information.

1. Mr John Sapphire was moving boxes from one side of the office to the other. (Box 1 and Box 9 will form two 3x3 magic squares.)

2. Miss Jade Smith was fixing the printer because it was leaving random dots on the paper. (Cells seperated by a black kropki dot are in the ratio of 1:2. Cells seperated by a white kropki dot are consecutive.)

3. Miss Ruby Miller was nervous about a new client and was pacing back and forth in the staff room. (The ruby-coloured lines are palindrome lines. They read the same from either end.)

4. Mr Oscar Gold was fixing the air-conditioning. (Digits on the thermometer increase from the bulb.)

Surveying the body, you conclude it was the work of only one person. You need to work out who killed the boss. (The sudoku will solve if you ignore the clues provided by the killer, but there is no negative constraint. Some clues associated with the killer may be accurate.)
