The accused are lodged at the central jail at Colvale following their arrest in connection with the incident which took place on the night of January 1.
Jayesh Bhandari, one of the four injured victims, died at Goa Medical College and Hospital yesterday, said inspector Jivba Dalvi.
The tourists, earlier booked for 'attempt to murder', are now facing the charge of murder, he said.
The group of tourists allegedly attacked the staff of a guest house at Calangute over a petty issue. Four people were injured in the incident.
Police have also seized the mini-bus in which the accused travelled to Goa.
