Merritt's home was damaged by the fire as well. Thirteen people were displaced in a predawn fire that damaged four homes in a neighborhood near Lawrenceville. The fire broke out before 4 a.m. Wednesday, Feb. 26, 2014 in a home on Morning Glory Lane and spread to adjacent houses, according to Gwinnett County fire Lt. Colin Rhoden. Rhoden said the house where the fire originated was a total loss, and the homes on each side of that house sustained roof and attic damage. The vinyl siding on a fourth house was damaged by radiant heat, Rhoden said. Red Cross assistance was called for the seven adults and six children displaced by the blaze, he said. A child and a pregnant woman were treated at the scene for minor injuries, Rhoden said. The cause of the fire has not been determined. JOHN SPINK/JSPINK@AJC.COM
