Funeral services for both 55-year-old Jennifer Mock and her sister-in-law, 65-year-old Lena Knight, were held Tuesday in Plantersville. Both women died from their injures within days of last Tuesday's blast.
Mock's grandson, 8-month-old Wyatt Smith, was also severely injured in the explosion but continues to improve at UTMB Galveston.
Investigators believe there was a propane gas buildup in the home that caused the explosion, but the investigation is ongoing.
