His body was found at the home of Hot Springs attorney Andrea Davis.
After investigating the case for about a year and a half, police turned over the file to the prosecutor.
But still, no charges have been made in this case.
Tonight, Anderson's family held a vigil in his honor and as a way to remind officials they will fight until an arrest is made.
Anderson's father says he even has a new found hope.
In an effort to prevent conflicts of interest, this case recently moved from the Garland County prosecutor to the Saline County prosecutor.
So Gary Anderson is expecting more action on this case very soon.
He said, "We just want to keep people aware we're not going away until something is done even if we have to come back here the next year, and the next year, and the next year. There's no statute of limitations on murder."
During the vigil, family and friends also wrote special memories of Anderson in a book and lit candles in his honor.
Anderson's family plans to meet with the prosecutor -- to get an update on the case -- Monday.
