Flames tore through a second-story unit at the Plaza Motel on El Dorado and Broadway around 2 am Saturday.
Firefighters say a man suffered some severe burns while escaping the fire -- but when they searched the room -- they found 63-year-old Griselda Nunez dead inside.
The fire was contained to that one single room -- and no other residents at the motel suffered any injuries.
The cause of the deadly fire is still under investigation.
