KIRO Team 7 Investigators have uncovered a serious case of high-tech harassment.

Investigative Reporter Chris Halsne tracked down how a cell phone was being used to put an elderly Seattle woman in a dangerous situation.

We've confirmed a local woman received hundreds of calls from the same number in less than a month.

Police couldn't help. A phone company that could have helped delayed taking any action.

KIRO Team 7 Investigators set out to not only stop the harassment, but track down the culprits.

It's after one o'clock in the morning, but a 92-year-old Seattle widow cannot yet go to bed.

Eva's phones are ringing.

After a long, slow struggle to get to the receiver, Eva already knows what's on the other end of the line.

Nobody.

Less than two seconds after she hangs up, it rings again, and again, and again. And not to be monotonous, but this phone does no stop making noise.

It jingles about 12 times a minute, 720 times an hour -- and on this evening, while KIRO Team 7 Investigators were there -- around 3,000 times.

The victim of the harassment says, "It's bewildering to me."

We're protecting Eva's identity. She told us she's worried she's a victim of intentional harassment.

"It's very disturbing to have someone awaken you and you know the telephone is going to ring again. It disturbs your entire life. I'm at my wits end and want to be able to resolve this."

Perhaps the most dangerous health hazard of all: in order to get some sleep, Eva has been taking the phone off the hook.

That disconnects her "Lifeline," a special medical emergency alarm that she wears around her neck.

"That puts me in jeopardy because I depend on my Lifeline," says Eva.

She filed a police report, but Seattle Police Department detectives say they the phone company was unwilling to solve the problem without a search warrant.

While they battled over client confidentiality, Eva's phone kept ringing for weeks.

Police may have to be patient and wait for the process to work, but KIRO Team 7 Investigators don't.

We traced the number calling Eva back to a Cingular Wireless cell. Prompted by our investigation, that company took action, but wouldn't tell us who owned the phone.

We found the guy anyway. His name is David Wong and he was less than forthcoming about what was going on.

Chris: "Why was the phone being used like that?"
Wong: "Actually, that phone is in my name, but my brother is using it."
Chris: "And who is your brother?"
Wong: "He, uh, loaned it out to some guy."

Wong can claim ignorance about who was using the phone, but he can't deny who was paying for it. Here's part of a cell phone bill in Wong's name. For example, on a Friday night in April, there are 18 consecutive calls to Eva's house in less than 23 minutes.

Chris: "Have you seen your bill?"
Wong: "Yah."
Chris: "What's it look like?"
Wong: "Just a bunch of numbers."
Chris: "Is it the same number over and over?"
Wong: "I think, yah, it is."

Chris: "You weren't interested, when you see your phone bill and all these phone numbers?"
Wong: "I don't look at it. I don't look at the bills. I just pay. Every month, I make a payment for him. I don't go through the bill and look at it."

His comments were a bit contradictory, something Seattle police noticed as well. They are still trying to determine motive and intention.

Chris: "You understand their (detectives) concerns?"
Wong: "Yah, I understand. I understand."
Chris: "But you don't have any answers?"
Wong: "No, I don't because it's not my problem."

Not his problem, but still one for Eva. Now, every time the phone rings, she wonders, will there be anybody there?

Cingular Wireless declined an on-camera interview, but did tell me on the phone, they don't believe the cell calls to Eva were a computer glitch. That said, the company continues to do business with Wong.
