Thank you so much for your response....I thought I'd give you an update on what's happened so far (who knows, it might help someone else in a situation like this as well). We contacted Yahoo! by email (which got us no where....we got nothing but a generic reply pretty much just saying that they received our email). So after talking to a couple of local internet guys, a district attorney friend, customer service at his ISP and at Yahoo! we where told that it would take a subpoena for Yahoo! or his ISP release what IP address the password change originated from. I'm not certain exactly who he talked to at the police station (the attorney friend said to contact the complaint division at the prosecuting attorney's office or the deputy prosecutor) but the guy that he spoke with informed him that what she had done was a misdemeanor, that he would send a subpoena to Yahoo! and his local ISP, and then she would be arrested and her computer seized. ((I realize this might seem a little extreme, but this is actually the THIRD time she's hacked his email addresses and it's getting to be extremely tiresome))

(Just fyi) a few things he took to the police station....evidence that she's done this sort of thing in the past, the email to the alternate email address which included the date/time that the password was changed, proof that the email acct that was hacked was in fact his, ISP customer service phone number, and finally Yahoo! customer service phone number (which was harder than hell to find!! LOL)

If anyone is curious as to what that Yahoo! customer service phone number is....it's 408-349-7572. There are a couple others that might be useful as well, they are 561-988-2621 & 212-381-6800 (Yahoo! in FL & NY).

Anyway, like I said, thank you Very much for your reply vee_ess ...I really appreciate it!
