Police found the smoldering body of Luis Guerrero, 18, on Tuesday, in an open field near the Chicago public library.
The teen, who moved to Chicago from Mexico when he was in fifth grade, was the victim of a bloody act of revenge launched by his ex-girlfriend 16-year-old Tia Brewer along with two of her friends, Francisco Alvarado, 18, and Jesus Correa, 18, police say.
Brewer, who used to date Guerrero, claims he had raped her and this was payback, but police haven’t found indication that she reported the assault, according to CBS.
Guerrero was lured to meet with the group past midnight at the West Chicago Public Library on Tuesday where Alvarado allegedly attacked from behind and strangled the victim with a belt.

The depraved murder was executed by  Alvarado and Brewer who stabbed Guerrero 16 times in the neck, cops say.
Then they threw his body into a car and drove him to a nearby field where he was doused in gasoline, provided by Jesus Corea, and set on fire in a fire pit.
Guerrero ran for his life, leading Alvarado and Brewer to run over him with a Jeep Cherokee.
They brought him back to a fire pit,  placed him under a bench, and set him on fire again,  alive. They left the scene, leaving him for dead.
His body was discovered around 11.30am on Tuesday by West Chicago Fire Department workers conducting a training exercise. He was found not far from Alvarado’s residence, police say.
Alvarado’s parents found blood stains in their Jeep and approached police at the scene of the fire pit, near their residence. Cops said they found blood on the Jeep’s undercarriage.
‘The facts alleged in this case are brutal and heinous and evidence of an unconscionable degree of depravity,’ State Attorney Robert Berlin said.

Jesus Correa, who was asked by the pair to buy gasoline used to set the victim on fire, was charged with concealment of a homicidal death and held on $100,000 bail.

Over the weekend of August 3 to 5, 71 people in the city were shot, 12 of them fatally, over course of just 60 hours.
