A man kills his parents in Barcelona and then commits suicide. The police force's first hypothesis is that a man has killed his parents - the woman in the Barcelona district of Sant Martí and the man in Molins de Rei.
In addition, the body of another man has also been located who would be the son of both victims and could be related to the perpetrator of the events. The Investigative Court 30 of Barcelona, acting as incident guard, is investigating the violent death of these three people from the same family.
