Sheriff Gary Gulledge and other county officials said Thursday they hope to add about 47 high-resolution digital cameras at about 21 locations along the trail during the first phase of planned security upgrades.
The 42-year-old woman was attacked July 29. No arrests have been made.
The expansion of cameras would be a dramatic upgrade, since there now only three sites with cameras along Paulding County's 18-mile portion of the trail.
The sheriff also hopes to purchase two more vehicles to patrol the trail.
Also Thursday, Gulledge announced that a reward fund in the case has risen to about $10,000.
