On 23 June 2011, Marshall and his girlfriend Meilyn Arianna Masís Castro were traveling on the Braulio Carrillo highway in Costa Rica when they were involved in a fatal car accident east of San José while on their way to Marshall's parents in
Limón. Marshall had scored the only goal for Costa Rica five days earlier in a match against
Honduras in the quarterfinals of the
2011 CONCACAF Gold Cup. His death was marked in several ways in his home country. The president of Costa Rica,
Laura Chinchilla, went on national television and expressed her sympathy and a memorial ceremony was held in
Estadio Eladio Rosabal Cordero, the stadium of Marshall's former club, CS Herediano. ==Career statistics==
