The Guadeloupe international, who was capped nine times by his country, made six appearances for the Pilgrims during the early weeks of the 2007-2008 season under the management of Tommy Taylor.
He is reported to have been killed in a road traffic accident
in Bouliqui on the Grande Terre Island on Monday — only four days after celebrating his 28th birthday.
Quistin later played against the Pilgrims for both Hednesford Town and FC United of Manchester.
The thoughts of Boston United are with the Quistin family at this sad time.
