They're still looking for people to come forward.
The PSNI have said that they've now identified 619 people who were in the queue or the car park of the Greenvale Hotel on the night that three teenagers died.
267 of these have been interviewed by appropriately trained detectives but police are still seeking people who have yet to contact them to come forward.
Detective Chief Superintendent Raymond Murray said: “We are very aware that this continues to be an extremely traumatic time for all of those who were at the Greenvale Hotel and witnessed the terrible events of that night. We have taken considerable steps to make it as easy as possible for them to provide their statements to police.
“Over 100 people attended the dedicated room at Burnavon Arts Centre and spoke to officers who are specially trained in interviewing young people. This facility has now closed and instead we are speaking to students at their respective schools. We are working closely with the local principals to accommodate this.
"As part of our investigation we have utilised the Major Incident Public Portal to allow people to upload mobile phone footage and images of the evening. We have been downloading mobile phone footage from people at the scene by using one of our Cyber Support Vehicles in Cookstown.
“It is still really important for anyone who has not yet contacted us to please come forward and work with police to help build an accurate picture of what happened that night.
“I would again reassure anyone with concerns, the focus of our investigation is not the age of people who were at the event – it is about trying to find answers for the families of the three teenagers who tragically died.”
