Authorities are trying to determine what caused a fire that killed a 37-year-old mother and her 8-year-old son in Orange.
The fire broke out in a home on Berkeley Avenue around 11:30 a.m. Sunday.
Officials say a passer-by banged on the door, but got no response.
The dead are identified as Tanji Dewberry and her son, Evan Solar.
