UPDATE: Woman killed in Van Zandt County house explosion identified
Van Zandt County, Texas (KETK) — An elderly woman was killed in an accidental house explosion in Van Zandt County around 5:00 p.m. on Sunday.
On Wednesday morning, authorities identified the woman as Rita Armstrong.
On Monday, Van Zandt County officials returned to the scene of the explosion to continue their investigation, and determined that the fire was accidental.
Authorities say that it was caused by a partially open propane valve on an unused line running into the house. The propane reportedly seeped into the house, and something ignited the vapors shortly after Armstrong arrived home.
