ACTIVITY:
We read the following text as a group and carry out the activities. Police report on the case of Professor John Carles
Preliminary: Professor John Carles was a scientist famous for his discoveries that developed his activity at Lleida University. Last month his body was found on the floor of the office where he normally worked. The room was scattered, with fallen objects and scattered drawers. The professor was in full investigation of a commercial product that, surely, would suppose a huge economic income for himself and the University. The dossier with this investigation was not in the office, so it is supposed to have been stolen.
Evidence has been collected at the crime scene and sent to different laboratories for identification: a glass of contaminated water, a suicide note written with a marker, the remains of a snack, a bottle of dirty water, a glass with traces of Cells and fingerprints.
Research
The staff of the University has been interviewed, his closest colleagues, those who also worked in similar investigations. From these conversations some interesting information has been extracted for the case. One of them is that Professor John was a manic of cleanliness and order and always kept his workplace flawless. His personal secretary has indicated that he was allergic to many substances considered to be very normal and therefore was very careful in his eating and scrupulous with his meals.
The autopsy has revealed that death was triggered by a heart collapse due to the accumulation of two allergens in his body. Any combination of two of these elements would have been lethal to Professor John Carles: salt, water with microorganisms, and onions.
Some evidence has also been found that may be conclusive. One of them is a suicide note written with blue and red markers. Professor John Carles could not write it because he always used a pen. The others are remnants of epithelial cells and fingerprints found respectively in a glass and in the drawer where he kept the documentation of his investigations. The cells of the epithelial mucosa were from John himself.

Professor Tomas Fravic. He works in an investigation along the same lines as John, but with no conclusive results so far. They are well-known in the University the strong discussions that they had between them, arriving sometimes to the serious insults. No one has seen him enter or leave the office of Professor John, in fact, his secretary says that he had been working in his home for a while and only communicated with her by email. The date of one of the e-mails confirms that the morning of the same day of the crime was not in the University, but it has not been able to verify if it made it appropriate to commit the murder without anyone suspecting. In his office have been located both salt and water with microorganisms, uses a green marker and his fingerprints were not in the drawer.
