Henry Vincent was killed during a break-in in Hither GreenCredit:Fiona Hanson Judge Statman added that while Vincent Snr’s previous conviction was an aggravating factor, he had been “out of trouble” for a substantial period of time.The trio appeared in court three weeks after 37-year-old Henry Vincent died during a break-in at the home of pensioner Richard Osborn-Brooks, 78, and his wife, Maureen, 76, in Hither Green, south east London, on April 4.Mr Osborn-Brooks was arrested on suspicion of murder but later released without charge. “You tricked your victim into believing that there had been some form of damage which may have been caused by a pigeon, that there was rot in the roof and furthermore, there was an infestation,” he told them.”You came along at various times to the home address and certain works were performed but not to an appropriate standard by any means. To put it in its most neutral form, any work that had been done was a botched job.”Your victim describes how your visits made him feel intimidated. This was all three of you taking on different roles as part of a joint enterprise to embark upon what was clearly a scam…You were all in it together.”This was deliberate targeting of a victim and he was a vulnerable person at the time.” An uncle and cousin of career criminal Henry Vincent, fatally stabbed in a botched burglary in Hither Green, have been jailed for swindling a homeowner out of £6,000.David Vincent, 50, and his 26-year-old son, also called David, ripped off Robert Etheridge by convincing him he needed urgent building work on his house in Dartford, Kent.They, together with another man, conned the 60-year-old, who was off work sick at the time, into believing his fascia boards were rotten and his loft was infested with rodents, bird nests and maggots. They also showed him three dead rats as part and tried to extort as much as £13,000, a court heard.Maidstone Crown Court was told the rogue traders wore jackets emblazoned with a company logo “Ideal Home Improvement” and used a van bearing the same name.Their deceit was discovered when Mr Etheridge contacted his insurance company and the firm alerted police.A genuine builder who later inspected the property concluded the work was “valueless, non-urgent and bodged” and that there were no infestations, the court was told.The father and son, from Orpington in Kent, together with 36-year-old John Baker, of Eltham, south east London, admitted fraud.Vincent Snr, who has a previous conviction for a similar scam, was jailed for 21 months. Father of three Vincent Jnr was sentenced to 18 months. Baker, a father of two, was also jailed for 18 months.
