His method of killing was brutal and unique, involving the bending of two pine trees to attach a victim's arms.4,5 He then released the trees, allowing them to snap back upright and tear the bodies of many men apart.4,5 Theseus, clearing the road from Troezen to Athens, defeated Sinis as his second labor by using the same method against him.3,5,4,2
