Gerrit Jan Heijn (14 February 1931, Zaandam – 9 September 1987) was a Dutch businessman, who was a top manager of Ahold until his murder in 1987.

His son, Ronald Jan Heijn, played for the Dutch national field hockey team.

Elsas was caught when he started spending banknotes of the ransom he received, of which the numbers had been recorded.

Elsas gave directions to Heijn's body, which was buried in the woods near Renkum.

Elsas was hit by an excavator on 3 August 2009 while riding his bicycle near the town of Vorden, Gelderland and died in a hospital at Zutphen.
