WAUSAU - A registered sex offender is back behind bars after an investigation by Washington County Sheriff’s Office, following reports of suspicious activity at the Wausau Post Office.

Brian Anderson, 48, was been charged with lewd and lascivious battery on a person under the age of 16. He is currently being held without bond in the Washington County Jail.

Reports of Anderson being seen with the juvenile for prolonged periods of time were received and Washington County Sheriff’s office began an investigation. After initial questioning by the deputy on August 25, the juvenile denied any contact with Anderson.

Washington County Sheriff’s Office received a call from the juvenile’s father on August 29, stating that the juvenile admitted to knowing Anderson. The juvenile stated that Anderson did have sexual contact with them on two separate occasions.

The Child Protection Team interviewed the juvenile who stated they communicated via text messages. There had also been meetings with Anderson where sexual contact had taken place.

Anderson was originally convicted of a lewd and lascivious act on a child under the age of 16 in Port St. Lucie, Florida, in 1996, at which time he served a prison sentence and was released in 2011.

“If a concerned citizen had not made this report we may have never known about the situation,” said Washington County Sheriff Kevin Crews. “It is important to protect our children and to do what is necessary if any concerning behaviors are witnessed. We cannot thank the citizen enough for reporting these incidents.”
