7:44 result the police apologized to the victim's families the forensic report revealed multiple stab wounds on the bodies of the four family members with a murder weapon a 20 semimetal kitchen knife found in the kitchen sink after being cleaned blood fingerprints and Footprints were found in several locations including walls stair railings sinks and bedrooms fingerprints collected from the scene matched those taken from duang xiang's home leading the police to suspect him of the crime the estimated time of the murders was between 3:30 and 400 p.m. on April 29th duang xang had a long-standing financial dispute with the ding family born in 1958 he and his wife chenan graduated from Hunan University of traditional Chinese medicine they started working at a traditional Chinese medicine shop owned by a British pharmaceutical company in the late 1990s during this time they met Ding jafang and his wife Quay and later

8:52 partnered to run a traditional Chinese medicine shop there are two versions of how the two families met one version says that in March 1999 Quay and her husband opened a traditional Chinese medicine shop in Northampton to expand their business they approached du angang and his wife who were working as doctors at another shop and proposed a partnership offering a 5050 split of shares and profits however due to UK Visa regulations du angang could only hold 1% of the company's shares so the families privately agreed to split the profits evenly this private agreement laid the groundwork for future conflicts the second version suggests that du angang facing Visa issues approached the dings with a proposal to start a business together with the shares and profit splits being the same as described regardless of how they met the two families successfully partnered and opened three more traditional Chinese

9:59 medicine shops due to the booming business however disagreements arose over handling cash and Tax Matters du angang suggested not recording thousand washing duut to their own Tes the DAV dams disagree visit the sharing it would jedly die julan and pran in the sh cash home this was eventually discovered escalating tensions further on July 25th 2001 qu gay partnered with a British business associate Paul Delaney to start another company by 2002 the conflict between the two families had become irreconcilable the dings stopped paying duang xang his share of the profits and after obtaining his permanent Visa du anang opened his own shop but still held 1% of the original Shop's shares dang's friends claimed that the dings intentionally withheld the shops accounts leading du angang to demand his share the dings however maintained that they didn't owe him anything the conflict dragged on for 5 years until

11:07 duang xang filed a lawsuit against the dings for his share of the prophets fearing the lawsuit the dings transferred ownership of their shops on November 22nd 2007 the Northampton County Court ruled in favor of du angang ordering the dings to pay him $30,000 for legal fee and to settle the profit dispute in a separate hearing local news reported that Quay transferred the $30,000 to do an Yang's account shortly after the Court's decision on May 7th 2008 the court once again heard the financial dispute between the ding family and the DU family after several hours of trial the judge ruled that the ding family had to pay the DU family $40,000 as profits from their Business Partnership to prevent the ding family from not paying the do family's lawyer requested the judge to freeze the ding family's property in bhen a suburb of Northampton as a guarantee for the compensation the judge granted this

12:15 request on the spot according to reports the ding family owned two properties in Northampton one was purchased in 1994 and had been rented out and the other was bought in 2001 which was the two-story house in woodon where the ding family lived before the incident according to British legal procedures the judge's ruling had to go through judicial registration to become effective which usually takes two to 3 days on May 9th 2008 the Court's ruling became effective but the ding family only stated that they had no money as they had declared bankruptcy it was found that the day before the Court's ruling became effective the ding family sold the house they were living in on a cash on delivery basis most of the proceeds were used to repay the house loan and the rest covered recent legal fees and other expenses leaving no remaining funds according to British law once a person declares bankruptcy their

13:21 debts are automatically cancelled therefore even though the DU family won the lawsuit they couldn't get a penny it was assumed that the matter would end there but a few months later duang xang unexpectedly discovered that the ding family was still living in the house they had sold upon investigation duang xang found that the ding family had sold the house to their close business partner Paul at 20% below market value duang xang reasonably believed that the ding family to avoid paying compensation had colluded with Paul to sell the house at a low price and took them to court again this lawsuit like a tug of war lasted for more than a year in May 2010 the Court ruled that the property transaction between the ding family and Paul was invalid the ding family and Paul appealed on the spot a few months later the Court ruled on the appeal reversing the decision and stating that the ding family sale of the

14:28 house would was not illegal the reason was that although Paul bought the house at a low price the condition was to lease it back to the ding family for 21 years therefore the ding family was renting the house and there was no Market disruption just before the Court's ruling the ding family's out property was also sold the ding family claimed that the proceeds were used to repay the loan on the property and other expenses leaving almost no surplus funds therefore the ding family had no assets that could be legally executed unwilling to give up dangan took the case to the high court on April 28th 2011 the high Court's judgment came out upholding the original ruling and requiring dang xang to pay $888,000 in legal fees to the ding family and Paul as a result duang xang not only spent more than $100,000 on the lawsuit but also had to pay legal fees to his perceived enemies in fact duang xang had long resigned from his company
