Investigators believe the victim of a fire at a home near Hadley Park on Monday was purposely set alight.

Leila Dawson, 48, was arrested in connection with the Dec. 30 fire that sent another woman to the burn center at Vanderbilt University Medical Center with serious injuries, the Nashville Fire Department confirmed.

She faces charges of attempted criminal homicide, aggravated arson and arson.

The victim was set on fire inside her own residence by the suspect, NFD reported. She was found on the front lawn of her residence.

Investigators did not release a motive for the assault, nor did they release further details on the injured woman.

Video from a neighboring residence shows a woman, later identified as Dawson, leaving the residence with smoke coming out of the doorway as she backs out of the driveway, NFD said in a release.

A Metro Nashville dispatcher said NFD responded to the fire call in the 2300 block of Alameda Street at 11:45 a.m. on Monday.

According to NFD spokesman Joseph Pleasant that day, the initial call came in saying that a person was on fire outside.

"When our crews arrived they found the patient and transported her to Vanderbilt University Medical Center with critical burns," Pleasant said Monday. "The duplex was also showing signs of fire s(o) our crews extinguished the fire."

Dawson remained in custody Friday afternoon in lieu of a combined $1 million bond, Davidson County Sheriff's Office records show. Davidson County general sessions court records only reported the aggravated arson charge against her on Friday afternoon.

It was not immediately clear if she had retained legal representation. The aggravated arson case has been scheduled for a general sessions hearing on Tuesday morning.
