That evidence was used in a review of the case, he added, which resulted in the remains being found and Satchwell's murder conviction.
A significant police presence will continue in the County Antrim town after disorder began on Monday following a peaceful protest over an alleged sexual assault.ACC Henderson said the violence was "racist thuggery targeted at ethnic minorities and police officers".
The constable said all footage of incidents was being reviewed and prosecutions would come."We're taking steps to increase available resources and are surging a significant number of extra officers, vehicles and equipment to those areas where the rioting is taking place," he added.The first protest was organised hours after two teenage boys appeared before Coleraine Magistrates' Court.
They spoke through an interpreter in Romanian to confirm their names and ages. Their solicitor said they would be denying the charges.ACC Henderson said: "This violence only serves to undermine the criminal investigation and cause further distress and turmoil to a young victim and her family.
"This violence threatens to derail the very pursuit of justice it claims to challenge."
ACC Henderson also said communities were impacted as "vital resources" were redirected.James Young, 81, was travelling home from a holiday on the Greek island of Rhodes with his wife when he fell about 5ft while being transported on an airport ambulift.
Mr Young was said to have landed "on his hands and knees" and was rushed to the Royal Infirmary of Edinburgh for treatment following the fall on 28 November 2023.Edinburgh Airport said it accepted the decision of the court and offered "sincere condolences" to Mr Young's family.
He suffered a punctured lung, spine fractures and a fractured pelvis as well as a flail chest, where multiple broken ribs cause the chest wall to become unstable and interfere with breathing.Mr Young, from Edinburgh, suffered a heart attack two days later and clinicians concluded "the totality of his injuries and medical condition were not survivable".
