Sims 2 castaway how to kill a sim?

Here's how to murder (or kill) a Sim. First you build a house without doors or Windows. Then set the house on fire and do not press "Extinguish".When the fire dies so does the Sim you have killed.I hope this helps is you are a Sim killer.

this happened to me but with another female sim.then,a weird sign appeared and a picture of a guy doing yoga and it said "A Sim has died,but their flower can be used in a special potion."then I heard Hannah Andrews(The Sim I don't play play Zoey Clarks.)cry or moan and fall down dead.then I heard 600x really sad music,I almost cried my pants off did not save the game (thank God.).
