FRENCH cops have been accused of a "cover-up" by the brother of a Brit who was shot dead with his family in the Alps.
Surrey engineer Saad al-Hilli, 50, his wife, Iqbal Al-Hilli, 47, and her mother, Suhaila al-Allaf, 74, were brutally gunned down in a BMW 12 years ago.

The family’s two young daughters survived the massacre near Lake Annecy in eastern France, although seven-year-old Zainab Al-Hilli was shot in the shoulder and beaten.
Cops found Zeena Al-Halli, 4, alive after she escaped the suspects by hiding underneath her mother's legs while remaining motionless for eight hours.

Zaid al-Hilli - who was arrested on suspicion of conspiracy to murder in 2013 but was later released due to insufficient evidence - called the original investigation a "deception".
The 63-year-old told The Times: "Most crimes are locally linked, I think it was not properly investigated.
"The original investigation was a deception, [an attempt] to deceive us. It was a local crime and has been covered up.
"They made allegations against me without any evidence, there was no attempt to look at a local motive right from the start... they have covered up three murders."
He claims Mollier was the primary target of the brutal attack - and his family was simply "at the wrong place at the wrong time".
While a ballistic report suggests Mollier was shot first, indicating he may have been the intended target, French cops investigating the case kept treating Saad as the main victim, Zaid claims.
Zaid has now hired William Bourdon, one of France’s best-known lawyers, to pursue a fresh investigation.
Meanwhile, a new state-of-the-art DNA testing could soon shed fresh light on the unresolved tragedy.
A French cold case unit in the Paris suburb Nanterre has ordered the "unsealing of the fragments" of the murder weapon - a Luger PO6, Parabellum 7.65 - so it can be retested using the breakthrough testing methods.
At least nine killed after New Year's Day stampede at shopping centreClothes that Sylvian Mollier and Zainab Al-Hilli wore on the day of the chilling attack will also be examined once more, as well as around 10 cigarette ends found in the vicinity.
The clothes set for analysis include a a helmet, cycling shoes, and sports clothing worn by Mollier when he was killed as well as Zainab’s shoes and clothes.
They will be studied in a specialist laboratory to find traces of any clues that could lead the way to solving the case.
An investigating source said: "It is hoped that new examinations will uncover DNA traces.
"If yes, then they will be sent for comparison with a national genetic fingerprint file which lists more than four million fingerprints, to see if there is a match."
The source added that DNA methods have improved significantly over the years since the murder investigation was first launched.
However, given its direct contact with the killer, most hope for a breakthrough resolution to the case rests with the gun.
Most of the weapon had been removed from the scene, but small pieces of the grip were found near the family’s BMW car.
