An investigator's report says smoke detectors were removed and not replaced in a home where a fire killed two children and injured four adults.
The fire killed 1-year-old Lattie Frenn and her sister, 3-year-old Quinta Frenn.
Clark County Sheriff Louis Rosandich said previously an investigation showed the April fire started in a bedroom where two boys were playing with lighters.
The report from state Division of Criminal Investigation agent Robert Powell says one resident told investigators all the smoke detectors were removed from the house southwest of Willard the year before because they were beeping to indicate they had low batteries.
The father of the children who died says he installed alarms in the home but some were not maintained properly.
