Well, see- you CAN kill multiple people in one scenario, all you need to do is write the full name in. This is why you can't write 'so and so dies after leaving his entire fortune to so and so,' because BOTH people would then die. XD There was a fanart spoofing this, where Mello had Willy Wonka leave him all of his money by writing exactly the above into the DN. The final panel was a grave marker that said 'MIHAEL KEEHL : Heir to the Willy Wonka fortune'
