The FBI is stepping up its investigation into the possibility that a University of Tennessee student hacked into the personal e-mail of Vice Presidential candidate Sarah Palin.
A person who identified himself as a witness tells 10 News that agents with the FBI served a federal search warrant at the Fort Sanders residence of David Kernell early Sunday morning. Kernell lives in the Commons apartment complex at 1115 Highland Ave.
David Kernell is the son of Mike Kernell, a Democratic state representative from Memphis.
A Department of Justice spokesperson confirmed there has been "investigatory activity" in Knoxville regarding the Palin case, but she said there are no publicly available search warrants, and no charges have been filed.
A separate law enforcement source confirmed to 10 News that a search warrant was served on Kernell's apartment.
According to the witness, several agents arrived at The Commons of Knoxville around midnight.
They presented their badges upon entering Kernell's apartment, where several students were having a party, and took down their names.
The witness tells us they asked him and those who did not live in the unit to go outside. He believes the investigators took about 1.5 to 2 hours taking pictures of everything inside the apartment.
He says Kernell's three roommates were also subpoenaed, and must testify this week in Chattanooga.
