China's Didi Chuxing suspends carpooling service following murder of a passenger

Didi Chuxing, China's largest ride-hailing service, has suspended its Hitch, one of its carpooling services, for one week as it investigates the murder of a passenger.

The victim was a 21-year-old air stewardess identified only as Ms. Li. State-run news agency Global Times reports that the incident took place in the evening of May 5, when she used Hitch -- which lets people headed to the same destination take a ride together -- to summon a ride home from Zhengzhou airport, Henan Province, after finishing work. The publication cites police reports that say Li was murdered by her driver using a weapon.

Didi has used facial recognition technology to verify its drivers since 2016. The technology is used to speed up registration of drivers when they initially sign-up, and also to prevent fraud when they log in to start a shift. The idea is that the app will only unlock when the driver account owner takes a selfie which should match with the record Didi has.

In the case of this tragic incident, that safeguard failed.

The suspect -- who has been named as Liu Zhenhua -- is not registered on its platform, according to Didi, but he was able to access it, and take rides, using a verified driver account belonging to his father. Didi said it did not prevent this because its facial recognition feature was "defective" that day.

It looks like there was a warning sign, however. The company said that the account had received a sexual harassment complaint before the incident -- it isn't clear if that was from the father, or his son accessing the account -- but Didi was unable to reach the account despite trying to make contact an apparent five times. Yet, despite the complaint, the account was allowed to log-in and take rides.

"Due to the imperfection of the arbitration rules of the platform, the complaint was not handled properly in subsequent days," Didi admitted in a statement.

Hitch is an inter-city carpooling service focused on commuting and distance-traveling that lets passengers cover the cost of fuel and a driver's basic costs. Didi's commercial carpooling services are not affected. The Hitch suspension starts tomorrow -- May 12 -- and Didi said it will use the time to review all of its registered drivers for "any cases involving mismatch of drivers and vehicles."

The company also pledged to revamp its operational approach and customer support system.

In a prior statement provided to TechCrunch, Didi expressed its "deep remorse" at the incident which it said it has "undeniable" responsibility for. The company added that it must "step up to win the trust of our users."
