A Leicester man found dead in a burning car in Nottingham is believed to be a former golf club owner who was convicted of drug dealing and fraud.
Police want to know why Mr Chenia was in Nottingham
Shokat Chenia, 45, was discovered stabbed to death in his silver Mercedes in a quiet neighbourhood of Wollaton on Thursday by firefighters.
Nottinghamshire Police are appealing for information about his movements in the day before his death.
They have not yet confirmed whether he was jailed for drug offences in 1999.
Previous BBC reports said Shokat Chenia was jailed for 12 years for hiding drugs with a value of £250,000 at a golf course he had built near his home.
He was found guilty of conspiring to supply heroin, cocaine, amphetamines and cannabis resin but that charge was ruled "unsafe" on appeal in 2003.
The case against him included surveillance tapes of conversations at the golf club.
An appeal court judge said the jury was not given a sufficient direction on the dangers of voice identification.
Chenia had said in an online statement written while in prison in Warwickshire that he was "an innocent victim".
He was also sentenced to eight years at an earlier trial for defrauding the golf club building contractors. His appeal on that conviction was rejected.
