Liverpool forward Diogo Jota was driving and likely speeding when his car crashed in Spain on Thursday, killing him and his younger brother, according to a preliminary police investigation.

Diogo Jota, the Liverpool star who died along with his brother in a car crash last week, was traveling over the speed limit, authorities in Spain said Tuesday. The Spanish Civil Guard’s investigation is still ongoing, but they said their belief is that Jota was driving too fast in his Lamborghini before a tire burst, forcing the car off-course.

Liverpool forward Jota and his brother Andre Silva were killed in a car accident in Spain in the early hours of Thursday morning.
