THE MILLS CASE A terrible murder took place on Monday 23rd, between 1 p.m and 2 p.m Mr Mills was shot in the head. He was working in his office in London, at number 55 Ash Road. He was sitting at his desk and writing an e-mail to his lover when he was killed. The investigators found a cigarette on the floor and fingerprints on his computer. They immediately ran a DNA test but the DNA on the cigarette was Mr Mills'. Nevertheless, they found three types of fingerprints on the crime scene: his wife's, his lover's and Mr Ruben's: that was a good start for the investigation.

Mr Mills was a 45 year-old man. He was married and had no children. He was working for Apple for 5 years when he was killed. He is generally described as a very kind and generous person.
