i will steal your children

[over the phone] Haha, hello, Diane! I'm parked outside you're house. Don't call the police, not as if they'll care anyhow, though! I want you. If you come outside and start a relationship with me, I won't have to. But if you don't ─ I'll steal your children. I'll take them, and I'll kill them. And the police, or anyone, matter-of-fact will never recover the bodies. You have 30 hours. Don't call the police or anyone in those hours, I'll know, and I also know where your youngest daughter attends school. [hangs up]
