I love solving fellow geocacher fuzzydave's Random Wiki Puzzles, so I decided to make a couple with his permission.
Don't go to the given coordinates, you will find nothing there, unless you enjoy taking a boat to the middle of a lake for no reason.
The final coordinates are located at N 38° 56.ABC' W 076° 28.DEF'
A = Last digit in the year of his birth.
B = Machado returned to Brazil in the 201B summer, joining Duque de Caxias, minus 1.
C = In the summer of 201C, he joined Persian Gulf Pro League side Saba Qom, plus 4.
D = Machado was one of the victims of LaMia Airlines flight D933.
E = First digit in the number of fatalities onboard the flight Filipe was killed on.
F = Month number Filipe was born in.
Once you arrive to the final coordinates, the cache is a magnetic nano cache on a nearby sign. Happy hunting!
