Eric Williams was charged with capital murder last night, after investigators say they found a confession in the deaths of two Texas prosecutors sent from Williams' personal computer. According to an arrest warrant affidavit, a search of Williams' home turned up an email whose author admitted to the killings and promised more attacks, reports the Dallas Morning News. The email had been sent to Kaufman County officials the day after Mike McLelland and his wife were killed, but it had been sent in a way that disguised who sent it. "The death penalty is a viable option," said the Kaufman County sheriff.
Another revelation: Authorities were able to get their April 12 search warrant based in part on the discovery by the FBI that Williams' home IP address could be traced to Lexis-Nexis searches about the two prosecutors in the weeks before either was killed. Williams' wife Kim earlier this week confessed to driving the car used in the killings, laying the blame for the murders on her husband. Williams says he was home when the murders occurred.
