Can you help solve this mystery?

Do you ever hear things that go bump in the night?

Aside from the never-ending parade of freight trains that seems to squawk, squeal and blow their incessant horns, I rarely hear a thing.

That's not the case for one woman who lives in the community behind The Soap Factory car wash.

The woman, who does not want her name used, called me last week, wondering if I could put on my investigative reporter's hat and figure out what the heck is making such a racket four nights a week near her home.

She said the sound compares to a dump truck slamming its tailgate against its bed to clean it out.

No, it doesn't make her house shake, but it is loud enough that it sounds as if the truck is sitting in her front yard.

"It's definitely metal on metal slamming together," she said.

If this were something that happened once in a while, I would chalk it up to just one of those things no one can really explain, like UFOs, high gas prices and just exactly what "changes" Obama has in store for America.

Instead, this happens four times a week and begins nearly like clockwork around 3:30 a.m.

When it first started happening, the woman, who said she's a fairly light sleeper, said it would wake her up.

Now, because it happens so often and at the same time each morning, her body's internal alarm clock has been reprogrammed and wakes her up just before the slamming begins - and the slamming can last 15 minutes or as long as an hour.

At first she thought it might be work going on at General Cable, which is better than a mile away so she has ruled that out.

She also considered construction at the new Rite Aid location, "but what could they be doing at 3:30 a.m.?" she said.

I asked about garbage trucks, but even those guys get to sleep at night, right?

To say she's a little unnerved over the mysterious noise is certainly understandable. It's bad enough when a yapping mutt wakes you up at night; at least you know what it is and how, if need be, to shut it up.

She is so concerned about the noise that she has called the police. So far, she hasn't received an explanation.

That's where I enter the picture and, I'm sorry to say, I can't come up with one theory that makes sense.

Now you get to enter the picture and hopefully point out the obvious. If you have any clues or ideas what's keeping this woman awake at night, please let me know at the e-mail below. If I get any rational sounding answers, I'll forward them on to her and see if we can't put this mystery noise - and this poor woman - to bed.
