By the way, the telephone company FOR FACT, has the technology to tell you with 100% certainty the point of origin.
+1!
Report this to the cops by all means, with the tape. They need to know this, and if they persue it they will be able to figure out the point of origin and (hopefully) at least inform you who you need to watch out for.
The person tried to mask their voice, and issued a threat. From the way I understand it, most child abductions are done by family or close friends - people you know. The hiding of the voice is, in my opinion, supportive of this possibility. Keep that in mind!
(Any crazy ex-girlfriends or female friends/acquaintances who have had a miscarriage or child die would, IMO, be prime suspects.)
It has been my experience that a serious criminal does not telegraph his/her intentions.
That doesn't account for
crazy people, though. And when it involves the kidnapping of a child - someone who wants one, likely a female - anything about "serious" or "reasonable" goes right out the window, and the closest thing to "serious" is "seriously crazy or deranged".
I'd guess you're being terrorized by someone you peed off or someone just has a sick sense of humor.
Either way, the person is dangerous. I'd say it's more likely the person is sick and has thought of the kidnapping, and may be acting out, testing the waters in an attempt to see if they can get away with it.
I tended to agree with Biker about someone serious about it probably would not have said they planned to do it. But what kept me second guessing that is the seemingly rather large number of crazies are out there that do this kind of junk.
Don't second guess someone's sanity. If someone says they're going to do something crazy that harms you, you've got to assume they're going to do so and make the appropriate preparations to defend and protect yourself, and to try to stop them (with the help of the police) before they're able to act.
I had a girlfriend for the first half of my freshman year of college who I dumped around spring break. I then transfered to a different school the distance of half the country away. Two years later I started receiving a series of abusive harassing and threatening emails and IMs, and noticing some linguistic similarities in the typing, I asked around with people I still was in contact with the school to find out it was her. She'd gotten into another relationship almost right after we broke up, and we'd cut off all contact with each other shortly after the break-up, so there was no reason to suspect she'd do something like this - other than the fact that, indeed, she was as crazy as a glue odor tester (which was, of course, the reason for the break up). So, don't under-estimate past crazies.
