Miami-Dade Woman Accused of Setting Man on Fire After Argument, Leaving Him With Burns Over 80% of His Body as Doctors Fear He Won’t Survive

Authorities say a 45 year old woman returned to a northwest Miami-Dade neighborhood hours after an argument, poured a flammable liquid over a 33 year old man and set him on fire. The victim was rushed to Jackson Memorial Hospital with life threatening injuries, while the accused now faces attempted murder and arson charges.

MIAMI-DADE COUNTY, Fla. — A 45 year old Miami-Dade County woman has been arrested and charged with attempted first-degree murder and arson after investigators accused her of deliberately setting a 33 year old man on fire following an argument Saturday evening, leaving him with catastrophic burns covering at least 80% of his body.

The accused, identified as Tanisha Shelton, allegedly returned to the Brownsville neighborhood in northwest Miami-Dade County on October 24 carrying a container of liquid accelerant, confronted Nathaniel Devon Mathis and ignited the liquid after pouring it onto him, according to allegations detailed in an arrest report cited by local news outlets.

Mathis suffered extensive second and third degree burns and was transported to Jackson Memorial Hospital’s Ryder Trauma Center, one of South Florida’s major trauma facilities. Medical personnel reportedly described his condition as extremely critical and indicated that he was not expected to survive his injuries.

As of the latest October 25 reporting reviewed for this story, Mathis had not been reported dead. His condition remained life threatening, and authorities had not announced any homicide charge. The Miami-Dade Sheriff’s Office is investigating the circumstances surrounding the attack, including the confrontation that allegedly preceded it, the substance used to ignite the victim and the events that led to Shelton’s arrest.

Investigators Say Argument Escalated Into a Deliberate Attack

According to an arrest report described by CBS Miami, Shelton and Mathis were involved in a verbal confrontation earlier Saturday. During that dispute, investigators allege, Shelton threatened to leave and return with someone who would harm him. Several hours later, Shelton allegedly returned carrying a white plastic bucket containing an unidentified liquid accelerant inside a plastic bag. Investigators say she approached Mathis and renewed the confrontation after obtaining a lighter from a witness nearby.

Police allege that Shelton then poured the liquid over Mathis and ignited it, causing flames to engulf him. The arrest report describes an intentional attack rather than an accidental fire, although the allegations have not been established in court.

Investigators have not publicly disclosed what caused the initial argument or whether Shelton and Mathis had a prior personal relationship. There is also no confirmed public evidence establishing whether the two were romantic partners, neighbors, acquaintances or otherwise connected.

Those unanswered questions are significant because the reported sequence of events could become central to prosecutors’ attempt to establish intent and premeditation. An alleged threat followed by a departure and return with an accelerant may be relevant to the attempted first-degree murder charge, but the prosecution must establish the required elements of that offense in court.

Witness Reportedly Chased Suspect and Used Pepper Spray

One of the more unusual details in the arrest report concerns a witness who allegedly provided Shelton with a lighter shortly before the attack and then attempted to stop her from escaping. According to the police account cited by CBS Miami, Shelton asked to borrow the lighter before approaching Mathis. After the fire began, a witness reportedly chased her and sprayed her with pepper spray in an attempt to prevent her departure.

The available reporting does not establish whether the witness who provided the lighter knew what Shelton allegedly intended to do. There is also no indication in the reviewed reports that the witness was charged with any offense.

The witness’s account could become important evidence because it may help investigators establish the sequence of events immediately before and after the fire. Detectives may also examine whether other people witnessed the confrontation or recorded any portion of the incident.

Deputies Find Victim Unconscious With Extensive Burns

The attack was reported at approximately 6:02 p.m. Saturday near Northwest 63rd Street and Northwest 25th Avenue in the Brownsville area of Miami-Dade County. Initial reporting placed the incident in a courtyard associated with the former Annie Coleman housing development.

Responding Miami-Dade Sheriff’s Office deputies found Mathis unconscious and suffering from extensive burns. Emergency medical personnel transported him to Ryder Trauma Center at Jackson Memorial Hospital, where he received treatment for life-threatening injuries.

Second and third degree burns affecting such a large portion of the body can produce severe complications, including fluid loss, infection, respiratory problems and organ failure. The extent of Mathis’s reported injuries makes his medical condition especially serious, although his individual prognosis must be determined by the physicians treating him.

The reported assessment that Mathis was not expected to survive should not be confused with a declaration of death. No death had been confirmed in the October 25 reporting supplied for this article.

Suspect Located Nearby and Arrested Without Incident

After the attack, deputies received a description of a woman reportedly wearing a brown dress and purple sneakers. Investigators located Shelton nearby wearing clothing that matched the description and took her into custody without incident, according to the arrest report.

Shelton was subsequently taken to the Miami-Dade Sheriff’s Office Homicide Bureau for questioning. The arrest report states that she invoked her right to legal counsel. Exercising that constitutional right is not evidence of guilt and should not be interpreted as an admission of wrongdoing.

Investigators have not publicly disclosed whether Shelton made any statements about the alleged attack before requesting an attorney. The reporting reviewed also does not establish whether investigators recovered the bucket, lighter or suspected accelerant or whether laboratory testing has identified the substance. These details may become important as prosecutors prepare the case and defense attorneys review the evidence supporting the charges.

Shelton Faces Attempted First Degree Murder and Arson Charges

Shelton faces two serious felony charges: attempted first degree murder and arson causing great bodily harm. The charges reflect prosecutors’ allegations that the attack was intentional and that the use of fire caused devastating injuries.

According to CBS Miami, Shelton was booked into the Turner Guilford Knight Correctional Center early Sunday. Jail records cited by the station listed a $10,000 bond on the attempted murder charge, while bond on the arson charge had not yet been set. Those figures reflect the records available at the time of the report and may change following subsequent court proceedings.

Attempted first degree murder requires prosecutors to prove the elements of an attempted intentional and premeditated killing. The arson charge involves separate statutory requirements, including the circumstances of the fire and the injuries allegedly caused. The exact charging language and supporting evidence will be examined during the judicial process. Shelton has not been convicted, and all allegations remain subject to proof in court. She is presumed innocent unless and until proven guilty.

The Victim’s Condition Could Affect the Criminal Case

Mathis’s medical condition remains one of the most consequential developments in the investigation. According to the arrest report cited by CBS Miami, he suffered second and third degree burns over at least 80% of his body, and medical personnel reportedly indicated that he was unlikely to survive. Despite that prognosis, the available reporting does not confirm his death. The distinction is critical because any subsequent death attributable to the injuries could prompt prosecutors to review the existing charges and consider a homicide prosecution, depending on the medical findings and evidence.

The Miami-Dade Sheriff’s Office Homicide Bureau’s involvement does not itself mean that Mathis has died. Homicide investigators may investigate potentially fatal attacks while victims remain alive, particularly when the alleged conduct could support an attempted murder charge. For now, the reported charges remain attempted first-degree murder and arson causing great bodily harm. Any change would need to be confirmed through updated court records or an official law enforcement announcement.

Questions Remain About the Relationship, Motive and Evidence

Several important aspects of the case remain unresolved, beginning with the relationship between Shelton and Mathis. Investigators have described an argument between the two but have not publicly established whether they were romantic partners, acquaintances, neighbors or otherwise connected. Without that information, the incident cannot accurately be classified as domestic violence.

The cause of the dispute also remains unclear. Police allege that Shelton threatened Mathis earlier in the day and later returned with an accelerant, but investigators have not publicly explained what prompted the confrontation or whether any earlier incidents involving the two had been reported to law enforcement.

Another unanswered question concerns the substance used in the attack. The arrest report describes an unidentified liquid accelerant, but the reviewed reporting does not identify a laboratory-confirmed chemical or establish where it was obtained.

The witness who reportedly supplied the lighter and later attempted to stop Shelton could also play a significant role in the case. Investigators will need to establish what the witness observed, whether other witnesses corroborate the account and what physical or digital evidence supports the alleged sequence of events.

These questions are not merely background details. They could influence how prosecutors establish intent, how defense attorneys challenge the evidence and how a jury ultimately evaluates the allegations.

A Brownsville Neighborhood Confronts the Aftermath

The alleged attack occurred in the Brownsville area of northwest Miami-Dade, near a former housing development. Local reporting placed the incident in a courtyard where deputies and emergency medical crews responded after receiving reports that a person had been set on fire.

Univision Miami interviewed neighborhood residents who described recurring disputes and concerns about conditions around nearby vacant buildings. Those accounts provide context about residents’ perceptions of the area but do not establish that neighborhood conditions caused or contributed to this particular attack. The severity of Mathis’s injuries has placed the case among the most disturbing violent-crime incidents reported in Miami-Dade this weekend. Beyond the criminal charges, the attack has left a man fighting for his life and witnesses confronting the aftermath of an incident that unfolded in a public residential area.

Investigation Continues as Victim Fights for His Life

As of the October 25 reports, Shelton remained in custody facing attempted first-degree murder and arson charges, while Mathis was hospitalized in extremely critical condition. Detectives continued investigating the circumstances of the alleged attack, including the earlier confrontation, witness accounts and evidence surrounding the use of the accelerant.

The case will now move through the criminal justice system, where prosecutors must establish whether the evidence supports the charges and defense attorneys will have the opportunity to challenge the state’s allegations.

For Mathis and his family, however, the most immediate concern remains his survival. With burns reportedly covering at least 80% of his body, his injuries are life-threatening, and the latest medical prognosis described his chances of recovery as extremely poor.

The central allegation is that an argument escalated into a calculated act of violence: a woman allegedly left the scene, returned hours later with an accelerant and deliberately set a man on fire. Whether prosecutors can prove that sequence beyond a reasonable doubt will be determined through the legal process. Until then, the investigation remains active, the accused is presumed innocent and the victim’s condition remains the most urgent unresolved development.
