A Terrace Heights woman died in an early morning house fire at 2810 Pilot Lane. The East Valley Fire Department says the fire started about 1 a.m. while a husband and wife were at home.  The husband, Randy Henry, escaped the house, thinking she was behind him.  He told authorities that once he got outside he realized she wasn't there.  He tried to help her get out of a window, but by the that time the fire was to intense and she died.  East Valley Fire Chief Michael Riel said "the initial report was that of an unknown fire, but while fire crews were en route their was a report of shots fired in the area. A Yakima County Sheriff's Deputy arrived first and it was stated that there might be a gunshot victim inside."  When fire crews finally got inside the home they found the woman dead inside.  Arriving firefighters found flames shooting 30 feet high because the fire was fueled by shrubs alongside the house.  Several pets were also killed in the fire.  The woman has been identified as 50-year-old Lori Henry. The cause of the fire is under investigation. Riel isn't sure what caused the gunshot sounds. He said "it could've been ammunition located inside the house, there are a lot of things inside the house which could've caused the sound."   The cause of the fire is under investigation.
