Two persons have died and a 140-year-old youth has been critically injured as a result of three separate fires in the District of Colmbia Monday and yesterday, fire official reported.

The dead were identified as Pauline Butler, 47, of 1426 11th St. NW. and Ambrose Dike, 34, of 1321 Kenyon St. NW. Both died of injuries suffered when they jumped or fell from upper windows of their residences in an effort to escape flames, according to D.C. Medical Examiner James L. Luke.

The injured youth was identified as Claibourne Watson of 1808 8th St. NW. D.C. fire and police officials said he suffered burns over half his body while attempting to put out a fire in unoccupied apartment at 1709 9th St. NW, where he and two other youths apparently were playing. Watson then leaped from a fourth-floor window and suffered further injuries, officials said.

He was listed in critical condition at Washington Hospital Center.

Investigators said the fire started when a stove the boys were using in the apartment turned over and ignited a mat on which Watson was sleeping. Watson then tried to extinguish the flames, but his clothing caught fire, officials said. The blaze was reported by two youths who apparently had been playing in the apartment also, according to fire officials.

Investigators said Mrs. Butler died of a fractured skull and internal injuries when she jumped or fell from the third-floor window of her apartment Monday afternoon. They said the fire stared in a mattress.

Mr. Dike died at Washington Hospital Center Tuesday as a result of falling from a fourth-floor window ledge where he had sought safety from a fire that broke out in is apartment building Monday morning, fire officials said. That fire also started in a mattress, officials said.

The medical examiner's office said both deaths had been ruled accidental.

In another fire Monday, D.C. firemen Homer Davidson and Rich Delcher rescued a 15-year-old mute girl from her home at 5118 8th St. NW. Officials said the girl was treated for smoke inhalation at Washington Hospital Center and released Tuesday.
