The Disappearance of Clarissa "Carrie" Culberson

Detailed public information on Doan's childhood or upbringing is limited. Acquaintances described him as two different people depending on context, a polite, even sensitive individual to some, and controlling and violent within his relationship with Carrie. He had a documented prior criminal incident before dating Carrie: he had shot a friend in the face over an affair with his then-girlfriend, a charge later reduced to a misdemeanor. Public reporting does not establish a documented developmental basis for the pattern of violence that followed, and none should be inferred beyond what is recorded.

Before any suspect was named, the circumstances of Carrie's disappearance, no forced entry, her own car missing with her, and headlights deliberately left off as the vehicle left the driveway, pointed to someone she knew and trusted enough to leave with voluntarily or under coercion rather than a stranger abduction. The intimate nature of the disappearance, paired with a car that vanished and was never recovered, suggested an offender with the opportunity, motive, and likely assistance to dispose of both the victim and the vehicle without immediate detection.

Doan matched this profile precisely. He was Carrie's boyfriend with a documented history of controlling and violent behavior toward her, was seen assaulting her the night she vanished, and had immediate access to family members, Tracey and Lawrence Baker, who were later charged with helping conceal evidence. His arrival at his half-brother's home shirtless and with blood on his chest hours after Carrie was last seen directly matches the deduced pattern of an offender requiring immediate assistance disposing of evidence.

Carrie was targeted specifically because of her intimate relationship with Doan and, according to the prosecution, because of her decision to pursue an active criminal complaint against him for a prior assault. Her upcoming court hearing on that complaint, scheduled for days after her disappearance, is central to the prosecution's theory that she was killed to prevent her testimony.

According to witness testimony, Doan confronted Carrie in his yard shortly after she was dropped off, physically assaulted her, and left the scene with her in her own car. He then sought out family assistance within hours, arriving at his half-brother's home for help before the two men left together, an apparent effort to dispose of both Carrie and the vehicle before daylight.

The pattern of coercive control that preceded the killing, monitoring Carrie's movements, smashing her car windows with her inside it, and repeated escalating physical assaults over roughly two years, reflects an established pattern of intimate partner violence rather than a single isolated act. The specific choice to also make Carrie's car disappear, beyond what was necessary to conceal a body, suggests an intent to erase evidence of her existence and movements as completely as possible.

The offense occurred at Doan's own residence, his clear anchor point, before he sought help from family members at a second, nearby location. Investigators focused search efforts on property associated with the Baker family, indicating investigators believed the disposal site, wherever it ultimately was, was likely tied to locations known and accessible to Doan's immediate family rather than a random or distant location.

Doan accepted significant risk, committing the assault at his own residence where a neighbor directly witnessed and heard the attack, then involving multiple family members in the aftermath, each of whom represented a potential point of exposure. That risk proved consequential: it was witness testimony from within his own family circle, along with the neighbor's account, that ultimately secured his conviction. Carrie's own risk was structural, arising entirely from her relationship to Doan and her decision to pursue accountability for his prior abuse through the courts, a decision the prosecution argued directly precipitated her death.
