Paana was in his early 70s and suffered a severe abdominal injury in Wednesday's explosion. He was listed in critical condition at the hospital earlier in the day.
Brown identified the other burn victims brought to the UC Davis medical complex as Kim Dickson, in her mid-40s, and 17-year-old Sunny Dickson. Sunny Dickson was transferred later in the day to nearby Shriners Hospital for Children.
Officials could not immediately say where the Dicksons and Paana were when the home exploded.
