His tomb cover showed two Coats of Arms: one is known to have been used by his father, the other is that of the House of Bjälbo.

Holmger's whereabouts after that are not known, but it has been speculated that he held Gästrikland north of Uppland for the next thirteen years.

According to Erikskrönikan, after defeat in the battle Holmger fled to Gästrikland but was captured, quickly brought to trial and beheaded in 1248.

The later manuscripts show that a special chapel was built to consecrate Holmger Knutsson in Björklinge, Norunda härad, in Uppland.

He lies buried next to his father in Skokloster (Sko Abbey) Church in Håbo, near Uppsala.
