Blountville, TN (WJHL)  — The Sullivan County Sheriff’s Office is asking for help locating a man they say violated sex offender registry laws.

George Frederick Matson, 78, is listed as a sex offender in Tennessee and, therefore, is required to check in every three months with authorities.

But according to the SCSO, Matson has not been in contact with authorities in a year.

Matson’s last known address was in the South Holston Dam area of Sullivan County.

The state website now lists Matson as “absconded.”

If you have any information about George Matson, call the Sullivan County Sheriff’s Office at 423-279-7500 ext. 222.
