One of the posts read: "Drinkin the pain away, ok let's get it."
Just hours before he appeared in court for his plea, the officers found another post that Davis was "on some s---."
Another instance of social media boasting came last week, when South Charleston police arrested a half-dozen males, in their mid- to late teens, for allegedly destroying a hotel room and spa area at the Wingate Hotel.
The suspects took pictures of themselves with cellphone cameras during the havoc and posted those photos on the networking website Twitter. The photos provided convenient, public documentation of the crime, South Charleston Police Officer E.M. Peterson told the Gazette last week.
"These kids handed me this case," Peterson said.
Social networking websites have become so useful for gathering evidence during investigations that law enforcement search the often-public forums almost as soon as a case crosses their desks.
"There's just a bunch of different ways technology can help prove a case," Plants said.
The prosecutor is also considering using Facebook to help select juries.
For example, if 100 people were selected in a jury pool for a particular case, Plants would assign a person to search the candidates' Facebook pages for information that would disqualify them for duty. Obviously, he said, the potential juror would have to set his or her profile to be publicly viewed.
"I have a general list of information about them -- where they work, if they're married, will they pay taxes," Plants said. "Think about how much more information there is on Facebook."
Plants said such a system is in the works.
