The cause of the fire that destroyed an RV travel trailer where a family of six in Donna was living is undetermined at this time, according to Hidalgo County Fire Marshal Homero Garza.

Garza said the fire is believed to have started in the kitchen area, and it is very difficult to narrow down a possible source.
