Police officers from north-east England are to share their pioneering DNA crime detection work with colleagues in the United States.
The force uses modern forensic techniques to reinvestigate unsolved crimes
Two senior Northumbria Police detectives and a forensic scientist are giving presentations at a conference in Tampa Bay, Florida, on Monday.
They will talk about the investigation into the murder of Richard Jones in South Shields on New Year's Day 2002.
Forensic evidence proved crucial in solving the inquiry.
Det Supt Ian Sharp, Det Insp Garry Dixon and Dr Cathy Turner, from the Forensic Science Service, will give the presentation at the National Institute of Justice's forensic conference.
Mr Sharp led the investigation into the murder of Richard Jones.
He will explain how the bitterly cold weather preserved evidence at the scene and how the offender was identified from a DNA profile.
Mr Dixon is head of Operation Phoenix, which is Northumbria Police's forensic review of undetected rapes and serious sex attacks.
Dr Tuner was assigned to work on Operation Phoenix when it started and is the lead scientist in the specialist area.
Mr Dixon said: "Operation Phoenix is the largest of its kind in the UK and we are now recognised nationally as being at the forefront of applying cutting-edge forensic techniques to investigations.
"We have been invited to play a key role in an important international conference, a clear sign that others are now waiting to follow Northumbria's route to success."
