Terrifying moment armed suspect carjacks beloved wife Katherine Guerrero in the middle of a busy Florida intersection before killing her and setting her remains on fire inside the stole vehicle

A Florida woman who was carjacked in broad daylight in a tense moment captured on video is believed to have been found dead in a badly burnt car.

Katherine Altagracia Guerrero De Aguasvivas, 31, of Homestead, was abducted at a busy intersection just before 6 pm on April 11. 

A witness in a car behind her filmed the frightening daytime confrontation and later called 911.

The footage shows a man in a ski mask and black hoodie get out of an Acura sedan and approach the driver's side of Guerrero's Dodge Durango, pointing a 10mm handgun at her. When Guerrero unlocks the doors, the man climbs into the rear driver's-side door.

Detectives with the Seminole County Sheriff's Office say the man climbed into the passenger seat before Guerrero resumed driving, while another man trailed behind them in the Acura sedan. 

Remains believed to be Guerrero's were found in a badly charred car hours later, and police continue to hunt for the suspects in the brutal killing.

Investigators believe the suspect ordered Guerrero to drive to a construction site, where a badly burnt vehicle was found later that day with a body inside

Speaking at a press conference on Saturday, Sheriff Dennis M. Lemma said he was appalled by the footage.

'It is incredibly frightening to watch the boldness of this suspect, this perpetrator getting out of the car, wearing a hood, carrying a weapon in broad daylight, getting in the vehicle,' Lemma said.

In a 911 call released by the sheriff's office, the witness urges, 'You need to do something now because I don't know what's going on.'

Less than two hours after the carjacking, police received reports of gunshots and smoke in Oceola County.

A badly charred vehicle, believed to be the Dodge Durango, was found at a construction site. While the body inside has yet to undergo formal DNA identification, police believe it is Guerrero.

A dozen 10mm shell casings and one projectile were also found at the scene.

'There is no clear indicator why somebody would do this,' Lemma said. 'But we do feel and believe...that this was not a random act of violence. The perpetrators knew exactly who they were going after, why they were going after them.'

Guerrero hailed from the Dominican Republic and was a United States citizen. She lived with her husband in the Miami suburb of Homestead, where the pair worked at a barbershop and beauty salon.

The carjacking occurred just four days before her 32nd birthday.

Investigators believe the 31-year-old was targeted and say her husband told her to keep driving when she told him she was being carjacked

Guerrero's husband said she was in the area to visit family, though investigators were unable to identify any relatives in Central Florida

Moments before stopping at a red light, Guerrero called her husband and told him that the Acura was following her and ramming into her SUV, Lemma said. Her husband instructed her to keep driving.

Investigators believe she was forced by the gunman to drive to the construction site, and the suspect was familiar with the area. 

Lemma added neither Guerrero nor her husband called police at the time of the incident.

'There’s a lot of unknowns, a lot of things that will leave people scratching your head,' he said.

'Why did she and her husband not call 911? I don’t know. Why did she stop at the red light? There’s a lot of things that we’ll absolutely never know, but this is a tragic incident nevertheless.'

Authorities have not released further details about the suspects in the case. 

Lemma said investigators do not know where Guerrero was heading.

Her husband told police she was in Central Florida to visit family, though investigators were unable to trace any relatives in the area.

The sheriff noted Guerrero's husband has cooperated with police and has no criminal record in the United States.
