I have also had an issue with this number.... This girl who goes by the identity of Kara Kelly on facebook started messaging me about 2 months ago. She seemed normal said she was new to my college and then turned out to be alittle sketchy. She would freak out if i wouldn't answer her and then used fake numbers pretending to be people close to me. When I confronted her about knowing she was doing this she vanished from my life (deleting me off facebook etc etc) She has since contacted many of my sorority sisters and When I tried to find out who this phone was registered to no information came up.
Here is the link to her facebook
