When you are trying to open the boarded up windows, if you are far away from him he will do a long jump towards you. Then it takes him a few seconds to recover to attack. Before he jumps, do not stand in the yellow circles. Instead, stand next to the wall opposite the windows. He will now jump to there, recover, etc. While he is recovering, pull down the boards. When he jumps into the light, attack him. Keep doing this until his and his wife's life runs out to complete the level.
