One Missed Call
It's an epidemic of accidental death! Multiple college students receive odd voicemails from themselves, messages from the future, and all they contain are the screams of their own deaths. A few days later, at the date and time of the message's posting, they die in mysterious accidents, and oddly enough, each have a candy in their mouths.
Note: Dark Horse published One Missed Call and One Missed Call 2 as a single volume.
