@Supersimkin2, that's quite a partial view though (as these things so often are); even Wikipedia gives quite a different impression:
After school Bamber's father financed a trip to Australia and New Zealand and a scuba diving course. While in New Zealand, Bamber broke into a jewellery shop and stole two expensive watches, one of which he gave to a girlfriend back in Britain. He also boasted, according to Claire Powell, that he had been involved in smuggling heroin overseas. One of his cousins said Bamber ended up leaving New Zealand in a hurry, because friends of his had been involved in an armed robbery.
He returned to the UK to work in restaurants and bars, which included working as a waiter in a Little Chef on the A12, but later agreed to return home and work on his father's farm. Although he reportedly resented the low wages, he was given a car and lived rent-free in a cottage his father owned at 9 Head Street, Goldhanger, 3½ miles from his family's farmhouse at White House Farm. He also owned eight percent of his family's caravan site, Osea Road Camp Sites Ltd., in Maldon, Essex.
A few weeks before the murders Bamber trashed and robbed the family business at Osea Road Caravan Park. This was only revealed after the murders when he was forced to admit to the robbery after girlfriend Julie Mugford came forward as a witness against him.
