Iain Lom was almost single-handedly responsible for bringing the Keppoch murderers to justice. When Dòmhnall Glas II (Grey Donald II)died his heir, Alasdair was too young to rule. The clan was governed by Alasdair Buidhe (yellow haired Alexander), uncle to the heir, until the young chief and his brother, Raghnall, returned from their education in Rome. A banquet was held in their honour at which both boys were murdered by 7 men (a father and his sons) from a branch of the family that coveted the chiefship. Iain Lom appealed to MacDonnell of Glen Garry to administer justice but achieved nothing. He then had to go into exile and appealed to Sir James MacDonald of Sleat to avenge the murder. This finally happened in 1665. The guilty party were surprised and killed at a house near Inverlair. Iain Lom is said to have decapitated the bodies with the dirk used in the murders. He took these grisly trophies to show to Glen Garry, as reproof for his earlier failure to do his duty. On his way he stopped at Loch Oich side and washed the heads at Tobar nan Ceann (The Well of the Heads) where a monument was later erected. He told the story in "Murt na Ceapaich" (The Keppoch murders)
