The Historical Enquiries Team is a unit of the Police Service of Northern Ireland set up in September 2005 to investigate the 3,269 unsolved murders committed during the Troubles (specifically between 1968 and 1998.
The team had three objectives:
Working with families was at the heart of the HET objectives, with a family liaison process in place, and the HET undertaking to provide each affected family with a copy of the relevant report.
It was headed by Commander David Cox, formerly of the London Metropolitan Police, and consisted of a team of 100 investigators and supporting staff, and a budget of £30 million.
HET was split into two distinct teams: Review and Investigation. The Review team was staffed by police officers employed and seconded from outside Northern Ireland, while the Investigation team has been recruited locally.
