The Mehlville School District is mourning the loss of one of its elementary-school students, who died this morning after being pulled from a house fire in Lemay.

Brian Davis, 7, was a second-grader at Bierbaum Elementary School, said Superintendent Eric Knost in a note sent to all parents and teachers of the school district.

Bereavement counselors, teachers and support staff are available for students and teachers at Bierbaum, who were informed of Brian’s death Monday morning, Knost added.

“We will work together as a school community to care for the family and all who are affected by Brian’s death,” Knost wrote. “Bierbaum Elementary maintains a very compassionate and nurturing environment filled with adults who care deeply about all children. As we work through this sad news, we should all keep our thoughts and prayers with the Davis family.”

The St. Louis County Police Department first received a call about the fire, in the 700 block of Hinder, at 12:19 a.m. Monday. The three occupants, Brian, his 13-year-old sister and his grandmother, were all sleeping when authorities arrived at the scene.

The 13-year-old woke up and then woke her brother, but they were separated in the smoke, according to St. Louis County Police spokesman George Vaughn. The girl got out of the house and the grandmother jumped from a second-story window, breaking her heel, Vaughn added.

Firefighters found Brian in his bedroom and pulled him from the house. He was pronounced dead at St. Anthony’s Medical Center, while his grandmother and sister were treated for injuries and released.

Doctors treating Davis said he most likely died of smoke inhalation, Vaughn said, since he did not appear to be burned.

The St. Louis County Bomb and Arson Unit is investigating the circumstances of the fire.
