WAUSAU, Wis (WSAU) A Wausau man is awaiting sentencing on charges of sending sexually-explicit text messages to an underage girl may face addition charges.

32-year-old William Hebbe reached a plea deal for exchanging sexual messages on Facebook with a 12-year-old. He asked her about her underwear and said he wanted to touch her all over. He'll be sentenced on December 14th.

Police also seized two computers and several cellphones from Hebbe's home last October. Prosecutors now say Hebbe used multiple emails and on-line names. They're reviewing more than 1,400 pages of transcripts from internet chat rooms. They believe there are several additional chats with underage girls. More charges may be filed later this year.
