The mob dragged "converso" victims from their houses and killed some. Old Christians who were in any way associated with New Christians were also attacked. The mob attacked the tax-farmer João Rodrigo Mascarenhas, a New Christian; although a wealthy and distinguished man, his work also made him resented by many. They demolished his house. Within 48 hours, many "conversos" were killed; by the third day all who could have escaped, often with the help of other Portuguese. The killing spree lasted from 19 to 21 April, in what came to be known as the Lisbon massacre.
