The shaft, illegally excavated, was 110 m (360 ft) deep and had a diameter of 25 cm (9.8 in).[1][2] To carry out a rescue, it was necessary to drill a parallel conduit of a greater diameter, in an operation in which more than 300 people intervened, plus numerous heavy machinery.[3] The operation received international media coverage.[4][5][6] After several setbacks during drilling, on 26 January at 1:25 am, Roselló's body was found between two layers of earth.
