A third suspicious fire in five weeks at the Lake Collins community northwest of Portal has neighbors, including Bulloch County fire Chief Christopher Ivey, unsettled. Around 10:30 p.m. Saturday, a lakeside doublewide mobile home at the end of Bowen Road suffered smoke and fire damage after a suspicious blaze ignited the home from underneath, Ivey said. The home was just a short distance from his own home and within walking distance of two other mobile homes that were destroyed by suspicious fires in March.
