This is in Lisbon.
The victims were a barber and a taxi driver and his wife, who were clients of the salon.
It is said that three gypsies entered the hairdresser's and one of them asked for a haircut, but probably due to the refusal to provide the service, during the lunch break, a conflict began between them and the barber, who was cutting the hair of a client who came with his wife, and so they killed everyone inside.
