Evidence inside a Beaumont home contradicted the account Brandon Chretien gave after Tammy Dawson was critically wounded, police say.
BEAUMONT, Texas — The first official account of Tammy Dawson’s fatal shooting came from the man now accused of murdering her. At about 2:40 a.m. June 6, Brandon Chretien called 911 and reported that Dawson had been shot while the couple struggled over a gun, according to reports citing a probable cause affidavit.
What followed was a rapidly changing criminal case. Officers found Dawson inside a bedroom closet with a gunshot wound to the head and a handgun resting on a bedside table, police said. Chretien was detained and arrested on an aggravated-assault charge. Dawson was rushed to a hospital with a catastrophic brain injury, died after life support was withdrawn, and became the named victim in a murder case. Eleven days after the shooting, a Jefferson County grand jury indicted Chretien.
The 911 call sent officers to the 8200 block of Heartfield Lane in west Beaumont, near Gladys Avenue and Major Drive. Chretien reportedly told the dispatcher that he and his girlfriend had struggled over a firearm before she was wounded. The publicly reported portions of the affidavit do not provide a full transcript of the call or say how long Chretien waited before contacting authorities. They also do not explain where he was when officers entered the home.
Responding officers detained Chretien while emergency workers attended to Dawson. She was found in the closet of a bedroom, police said, while the gun was on a nearby bedside table. That separation between Dawson and the weapon became one of several publicly known details in the investigation, though authorities have not explained what significance they assigned to it. Officers secured the home, and detectives and crime-scene personnel began documenting the room and collecting potential evidence.
Police remained at the residence for several hours. Local television footage showed investigators working at the property as the inquiry continued. Reports said personnel took photographs and gathered evidence but did not identify the items removed from the house. Beaumont Animal Care was asked to take custody of a small dog that had been inside. The request appeared to be a practical step while the home remained an active investigative scene.
Dawson was transported by Beaumont emergency medical workers to a local hospital, identified in later reporting as St. Elizabeth Hospital. Doctors treated her for a traumatic brain injury. Police described her condition as critical and later said the wound had left her in a persistent vegetative state. At that stage, the case was treated as a serious assault because Dawson remained alive, although her injuries were life-threatening.
Investigators arrested Chretien before leaving the scene. The initial allegation was aggravated assault with a deadly weapon causing brain injury or paralysis, described in local reports as a first-degree felony. A magistrate set his bond at $1 million. The conditions attached to any release included continuous GPS monitoring, a ban on possessing firearms and restrictions on contacting Dawson or witnesses, according to reports from the initial hearing.
Even before Dawson’s death, police said the evidence conflicted with Chretien’s account in a critical way. Investigators determined that the gunshot wound was not self-inflicted and alleged that Chretien had shot her. A finding that the wound was not self-inflicted does not, by itself, publicly explain every circumstance of a shooting, and authorities have not released the full forensic basis for their conclusion. Police nevertheless treated Chretien as the person responsible and continued building the case.
The medical crisis then became a death investigation. Dawson’s family and friends gathered at the hospital as her condition failed to improve. Local reports differ on the precise date used to record her death. The Beaumont Enterprise reported that she was pronounced dead June 7, while KFDM reported that doctors removed her from life support late on the morning of June 8. The reports agree that she died from the injury suffered in the June 6 shooting.
Dawson’s 4-year-old son and other family members were with her before life support was withdrawn, her friend Mira Lee told KFDM. Lee said she rushed to the hospital when she learned Dawson had been shot. She described seeing a friend known for laughing and energy lying unconscious. The details shifted the story beyond a police call and an arrest, showing the immediate effect on a child, relatives and friends who had known Dawson for years.
Lee said Dawson had worked at a daycare and was an organ donor. She told the station that eight people were expected to benefit from donated organs. The account was not part of the criminal allegation, but it became an important part of how Dawson’s friends described the days after her death. No information about organ recipients was made public, and their identities are ordinarily protected.
Once Dawson died, the original charge no longer described the full alleged result of the shooting. Police said an upgrade to murder was expected, and prosecutors later changed the case accordingly. By June 12, local reporting said Chretien was being held on a murder charge while the district attorney’s office prepared to present the matter to a grand jury. His bond remained $1 million.
The grand jury considered the case June 17 and returned a murder indictment. That action allowed prosecutors to move forward in district court on the allegation that Chretien intentionally or knowingly caused Dawson’s death. Reports described the offense as first-degree murder, though the full indictment was not included in the available coverage. The exact language of a charging document matters because it identifies the legal theory prosecutors intend to prove.
The indictment did not settle the factual conflict that began with the 911 call. Chretien’s reported account described a struggle and a gun firing during that encounter. Police said their evidence showed Dawson did not shoot herself and that Chretien fired the shot. The available reports do not say whether Chretien later repeated, changed or withdrew his initial statement. They also do not identify any eyewitness to the shooting.
Several parts of the chronology remain incomplete. Authorities have not publicly said what started the alleged struggle, who first had the gun or how Dawson came to be inside the closet. No detailed ballistics analysis, firearm examination, autopsy finding or blood-pattern evidence has been released. Police have not disclosed whether they recovered text messages, surveillance footage or other records that might help establish what occurred before the call.
The relationship itself has been described in different terms. Police initially said Chretien and Dawson were dating. Later reports called him her boyfriend or estranged boyfriend and said they were still living in the same home. Lee said Dawson had told her that she was trying to leave the relationship and that she had noticed signs that troubled her. Those statements may provide context, but the publicly available reports do not indicate whether prosecutors included them in the grand-jury presentation.
The case also contains small reporting differences that may be resolved by official records. Dawson was identified as 24 in one early report and 25 in later coverage. Chretien was identified as 44 in the initial reports and 45 after the indictment. The street name appeared as both Heartfield and Hartfield in separate accounts. The probable cause affidavit, indictment, jail record and death certificate would be the controlling sources for those details.
Chretien has not been convicted, and prosecutors bear the burden of proving the murder charge beyond a reasonable doubt. A grand jury hears evidence presented by the prosecution and decides whether probable cause exists to issue an indictment; it does not conduct a criminal trial or determine guilt. The defense will have an opportunity to challenge evidence, seek records and present its account through the court process.
As of the latest reports reviewed, Chretien remained in the Jefferson County jail under the $1 million bond. No plea, trial date or next hearing was announced in the available coverage. The investigation that began with his early-morning call is now a pending murder prosecution, with the meaning of that call and the evidence found inside the home likely to remain central issues.
