Trecco Bay murder inquiry over Conner Marshall's death
A murder investigation has been launched after the death of an 18-year-old man who was attacked at a south Wales caravan park.
Conner Marshall, from Barry, Vale of Glamorgan, was found in a life-threatening condition outside a caravan at Trecco Bay Caravan Park, Porthcawl, in the early hours of Sunday.
He was taken to Cardiff's University Hospital of Wales but died on Thursday.
South Wales Police have renewed an appeal for witnesses.
Detectives want to hear from anyone who heard or saw anything suspicious in the Cedars, Firs or Beeches areas of the park between midnight and 07:00 GMT on Sunday.
Det Supt Paul Hurley said: "This was a brutal attack upon Conner with fatal consequences.
"I believe the person responsible may have shared information with friends, relatives or neighbours and I would urge anyone who has information or who may have been in the area of Trecco Bay between midnight and 07:00 on Sunday 8 March to contact the police.
"I would like to reassure residents and visitors to Porthcawl and Trecco Bay caravan park that this appears to be an isolated incident on a well managed site."
The force said staff at the caravan park are working closely with officers.
