LA CROSSE, Wis. -

The children of a western Wisconsin man convicted of killing his parents will inherit part of their grandparents' estate.

Probate records filed in La Crosse County Circuit Court show Eric Koula's two children will split $740,000 when they're older.

Koula is serving two life sentences for the deaths of his parents, Dennis and Merna Koula. The couple's daughter will also receive $740,000. The parents' will named Koula and his sister as representatives of the estate. But a judge removed Eric Koula following his arrest.

Prosecutors argued at Koula's trial that his deep debt and floundering day trading career drove him to kill his parents for the inheritance. The La Crosse Tribune  reported Koula, his wife and two children continue to believe he's innocent.
