Is this the news article?
[ The police found no evidence that PRC Ferrari driver Ma Chi (马驰

has consumed any alcohol in the night before the fatal accident in Bugis, said a police spokesperson to the media.
Ma was suspected of drink-driving and crashing his Ferrari into a Comfort Delgro taxi at a junction between Rochor Road and Victoria Street in the early hours of last Saturday morning, killing him on the spot.
The Singaporean cabby 52 year old Cheng Teck Hock and his Japanese passenger Shigemi Ito died later of their injuries in hospital.
The police claimed it ran blood tests on Ma Chis blood taken at the scene of the accident and confirm that it did not contain any substances which can cause him to become drunk.
The findings seem to contradict an earlier report by The New Paper claiming that Ma Chi reeked of alcohol when his body was extricated from his wrecked Ferrari. ]
(Found no evidence) does not mean he was not drunk. It means they could not find evidence that he was drunk.
Running blood tests on Ma Chis blood
taken at the scene of the accident may or may not be a scientifically sound basis to confirm conclusively.
If they chose not to take the blood sample from the body of the deceased but instead chose to take the blood sample from the
scene of the accident, then it does not make any sense at all.
His blood was spilled all over the car and street. Whatever alcohol substances his spilled blood may have contained could have evaporated or be contaminated.
There could be witnesses to the New Paper report to substantiate the body was reeking of alcohol.
If the checking is thorough enough, they could easily run a check with all the major KTVs and nightclubs to check where Ma Chi entertained himself and whether he drank in the KTV/night club. If he paid with a credit card at the KTV/nightclub, it is a solid electronic record with date time stamp.
Other KTV guests could also be witnesses that he was there and whether he drank. A big spender like that would be known.
CCTV records of the KTV/nightclub car parks will also show the license plate number of the Ferrari at that date-time.
But judging from this news article, it looks like they want to let it go and
everyone pretend to be stupid. Perhaps we don't want to know and let the matter be quickly forgotten. Next week something else will big news.
