BEIJING (AP) — Tesla says it can’t verify whether a vehicle autopilot system is to blame for the death of a Chinese man whose father claimed on state television that the driver-assist feature was active.

State broadcaster CCTV aired a report Wednesday about a January crash that killed 23-year-old Gao Yaning. The report included apparent dash cam footage of the car slamming into a slow-moving orange truck.

The report includes allegations that the car’s autopilot feature was active at the time of the crash. Gao’s family has sued Tesla in a Beijing court.

But the electric-car marker said in a statement that the family hasn’t cooperated with its efforts to obtain data from the wreck.

Tesla is under federal investigation in the United States for another fatal crash in May.
