A merciless California woman doused her roommate with gasoline and torched her with a lit cigarette before taking a seat to watch the writhing victim burn, authorities say.
Chasety Reynolds, 32, remained jailed Friday on $550,000 bail in the gruesome assault against Victoria de la Fuente, who suffered burns over more than half her body.
"I have never seen a case as disturbing as this," Police Commander Steve Rossi told a news conference in Lemoore, Calif.
When cops were called to the scene by a terrified good Samaritan, they found Reynolds cleaning off her driveway with a hose - while the badly-burned victim was a few feet away inside their home.
Reynolds' two kids, ages 9 and 12, were home when their mother set her roommate on fire, police said.
Reynolds, after igniting the woman, sat on the garage floor and watched as the flames engulfed de la Fuenta. A passing motorist who saw the fire rescued the burning woman as Reynolds stood impassively.
"Chasety ain't a human being," the victim's son, Michael Ybarra, told KSEE-TV. "There ain't nothing human about her."
The 46-year-old victim was listed in critical condition with second- and third-degree burns at the Community Regional Medical Center in Fresno, Calif.
Authorities were unsure what sparked the attack, although cops were called to the pair's home about an hour earlier when neighbors reported a loud argument between two women.
Reynolds greeted the responding officers, telling them everything was fine, before the dispute resumed and escalated.
