Earlier Paya’s family had cast doubt on the government’s assertion that the crash was the result of an accident and said they believed Paya had been targeted.
Paya was traveling with another Cuban dissident Harold Cepero, Spanish politician Angel Carromero and Swedish politician Jens Aron Modig when the rental car they were driving in crashed Sunday near Las Gabinas, Cuba.

The Cuban interior ministry report said that the crash took place when Carromero, the driver of the rental car, failed to slow down as the car reached a section of road being repaired.
The report quoted witnesses as saying the car was traveling more than 100 kilometers per hour (60 mph) when it lost control, went off the road and crashed into a tree.
The report noted that it is against the law in Cuba to drive above 60 kilometers per hour on an unpaved road and to lose control of a vehicle.
Spain’s Embassy in Havana had earlier said Carromero was behind the wheel when the crash occurred and that Carromero, was mentally traumatized by the accident.
Neither Paya nor Cepero were wearing seatbelts, the statement said. Paya died immediately, the statement said, and Cepero passed away after being brought to a nearby hospital.
Jens Aron Modig told police, according to the report, that he was dozing off at the time of the accident and woke as the car was going off the road only to lose conciousness as the car crashed.

Carromero told police, the report said, that he had not seen any signs warning of the roadwork and was not aware of how fast he was driving when he hit the brakes.
Both men were released from the hospital a day after the crash and have been questioned for several days by Cuban police.
