STAMFORD, Conn. (AP) — It appears that one of the victims of the Christmas Day fire in Stamford, Conn., died while trying to rescue one of his granddaughters.

The mayor of Stamford says Lomer Johnson was found outside the home, on the roof of a small porch off a bedroom. He says Johnson may have been trying to reach his granddaughter, or was leading her out.

Johnson, his wife and their three granddaughters died in the fire. His daughter, New York advertising executive Madonna Badger, and a male acquaintance escaped.

Johnson had worked as a department store Santa Claus in New York this season after a long career as a safety chief at a Kentucky liquor maker. A former company executive says Johnson "spent his career trying to keep others safe."

Investigators today are expected to reveal the cause of the fire. But the mayor says it appears to be related to a fireplace in the home.

He says a rescue team was able to get into the house as it burned, but they weren't able to stay because the fire was so intense and spread so quickly.

A retired fire captain says the fire department is now arranging crisis intervention for the firefighters who battled the blaze.
