Tamisha Davidson Fire: High Schooler Headed For College Killed In Blaze While Visiting Boyfriend

A Chicago teen described by family and friends as "loving" and "open-hearted" was killed in a house fire early Thursday.

Tamisha Davidson, 18, was visiting her boyfriend's house at Waller Avenue and Iowa Street in the city's South Austin neighborhood when the fire broke out around 12:40 a.m., reports ABC Chicago.

Davidson, whose body was found in the second floor apartment, was pronounced dead at the scene.

An 18-year-old male also was injured in the fire when he jumped from a second-floor window to escape the blaze, according to CBS Chicago. His father caught him on the ground, and we was later taken to a nearby hospital and treated for "bumps and bruises."

Firefighters believe the extra-alarm blaze started in the attic, while WGN reported the intense fire engulfed the entire top floor of the house. The fire was too intense for crews to enter the home, so firefighters had to battle the blaze from outside.

Witnesses say five or six people may have been in the row house when the fire started, while Davidson's family told NBC Chicago they don't know why Tamisha was the only one to not make it out.

"Maybe we'll never know the truth, because she's not here," Davidson's sister, Gabrielle Thomas, told NBC.

The Austin Career Education Center student had recently been accepted to college and was interested in studying mortuary science.

The teen's social studies teacher, Adam Wagener, told CBS, “She was always pleasant, very willing to help. She’s a very intelligent young woman, who never had a bad thing to say about anyone, never came in with a bad attitude.”

Officials are looking in to the cause of the fire, which was finally put out around 1:38 a.m. Firefighters reportedly told the family the cause was likely an electrical fire.
