Police have returned to Haytor on Dartmoor this morning as they continue their investigation into the deaths of Katherine Hooper and her five year-old son Joshua who fell from rocks last Friday.
Detective Superintendent Paul Burgan who is leading the investigation told ITV News West Country that its thought the pair spent the night there before they died.
Miss Hooper's 2 year-old son Sam was found dead at the family home in Paignton.
Detectives are appealing for anyone who was at Haytor last week who may have inadvertantly filmed or photographed Kat Hooper and her son on the THURSDAY carrying a car booster seat.
