A woman has been arrested for a fire that damaged 3 mobile homes on April 12 near Wyoming Avenue and US-95. Clark County Fire Department responded to the fire shortly before 11:30 a.m. A bystander told a firefighter that a woman needed medical help. The firefighter approached the woman, later identified as Heather McDonald. The firefighter asked McDonald if she was in the mobile home when it was on fire and she reportedly responded "yes, I started the fire." The firefighter then asked her if it was an accident or intentional and she replied "on purpose." McDonald also reportedly told the medical team at the scene that she started the fire. She told them she did it because she "they" were trying to evict her so that the home could be used to sell heroin.
