According to a 15th-century historian Ericus Olai, he was murdered at his home in Asknäs in Ekerö parish by the Lake Mälaren in 1206, allegedly by Russian pirates.

Death According to Eric's Chronicle

According to the Eric's Chronicle, after being away for nine years, Jon Jarl was killed on his farm at Askanäs on Ekerö by Karelian or Russian pirates the same night that he returned from a crusade between Ingrians and Russians. The Chronicle states: :''Thz er swa sant som jak her læss'' :''Jon jerl ward dræpin i askaness'' Jon's wife fled across the bay to Hundhamra (i.e. Norsborg), and gathered a mob to kill the perpetrators. They caught up and fought them off at "Eesta skär" (i.e. {{ill, Estbröte, sv, Estbröte, a high islet in the fairway between Ekerö and {{ill, Johannesdal, sv, Johannesdal, in the southwest of Stockholm). How accurately the chronicle reproduces the actual sequence of events is unclear.

Tombstone

An undated tombstone in Linköping Cathedral labelled "Johannes dux" and "the terror of the heathens" is probably that of Jon Jarl. {{S-start {{Succession box , title = Earl of Sweden , years = ?-1206 , with = , before = Johan Sverkersson , after = {{ill, Knut Birgersson, sv, Knut jarl {{S-end
