Shenzhen police said that DNA tests have confirmed that the driver who turned himself in after a deadly accident on May 26 is not a fall guy.

The statement was in response to widespread public doubts that the man, who turned himself in seven hours after the crash, was not the real driver.

The fall-guy speculation was rife even after the police on May 29 released videos and pictures related to the accident, which killed a taxi driver and two young women.

According to an earlier police statement, the man - surnamed Hou - is suspected of drunken driving.

In the latest press conference on May 30, the police also released original videos, in addition to the videos shown in the previous press conference that were captured from surveillance.

The videos showed a sports car hitting two taxis on Binhai Avenue at 3:08 am, a fire truck arriving at the accident scene, and Hou drinking in two bars in the Futian district with three women before they left in the car at about 3 am.

The police said that after the accident Hou called a friend to pick him up and take him to a yacht club where friends persuaded Hou to turn himself in.

According to Xu Wei, deputy director and spokesman of the Shenzhen traffic police bureau, blood samples taken from the sports car were more than 99.99 percent identical to Hou's blood. The figure, theoretically, means the blood was Hou's, the police said.

One of the three girls in Hou's car, surnamed Sun, also identified Hou as the driver during an identity parade at the police station.

The public earlier suspected that Hou was a fall guy for the car owner Xu Chuhui, the nephew of Xu Hanzhou, a construction company owner.

But police said on May 30 that investigations showed that both Xu Chuhui and Xu Hanzhou had an alibi. Hou worked for the construction company and earned about 3,000 yuan ($470) a month, the police said.

Hou is from a village in the Guangxi Zhuang autonomous region, has four brothers and sisters, and his parents were both farmers, the police added.

Meanwhile, relatives of one of the young women killed in the accident said that they remain skeptical.

“The crucial videos showing close-ups of the collision and how the driver ran away are absent, and we are not convinced,” the uncle of one of the victims, a 23-year-old surnamed Zhang, said after attending the latest police news conference.

The Shenzhen people's procuratorate said on its micro blog on May 30 that it has stepped up the investigation of the accident, and has met the traffic police for further information.
