Two children remained hospitalized Tuesday as a result of burns they received in a fast-moving fire at Noisette Creek Apartments in North Charleston last week.

Dortez Gordon, 3, is in critical condition at Medical University Hospital and 1-year-old sibling Javez Gordon is listed in fair condition, according to a hospital spokeswoman.

Their mother, 23-year-old Daysha Lewis, also was burned in the Friday morning fire, North Charleston fire officials said. She has since been released from a burn center in Augusta, according to the facility.

Neighbors helped to rescue the family after flames ripped through their eight-unit building. Lewis reportedly tossed her infant from a second-floor window to neighbor Reginald Curry and then jumped to the ground herself. Curry has said he kicked in the front door and rescued the 3-year-old, who was lying on a couch and unresponsive.

Neighbors have said all three were badly burned.

The cause of the fire is still under investigation, according to Bianca Sancic, a fire department spokeswoman.
