A Beloit woman pleaded guilty Thursday to conspiring to intimidate a witness in connection with a federal heroin investigation, according to a release from the Department of Justice.
The release said Tiana Williams, 25, will face a maximum penalty of five years in federal prison. She is scheduled for sentencing June 4.
According to the release, the prosecution established Christopher Evans, the subject of a federal grand jury investigation, assaulted a drug customer and was taken into custody on a probation violation. While in jail, Evans asked Williams to persuade the victim to change his testimony.
The release said Williams drove to the victim's residence in September and attempted to meet with him to convince him to change his testimony.
The release said Williams admitted she was involved with Evans in a conspiracy to distribute heroin in Thursday's plea hearing. She will be sentenced as if convicted of drug conspiracy.
