In September 2008, a brutal home invasion in Albuquerque, New Mexico shattered the life of 17-year-old Brittani Marcell. Attacked with a shovel inside her own home, Brittani suffered catastrophic brain injuries that erased her immediate memories of the event and forced her to relearn basic motor skills. For nearly a decade, the case remained an agonizing cold case until a combination of recovered memory, advanced DNA profiling, and investigative persistence led to the arrest and conviction of Justin Hansen. This case stands as a landmark study in trauma recovery, memory retrieval, and the relentless pursuit of accountability within the criminal justice system.
The journey toward accountability wasn't straightforward. Because Brittani suffered severe trauma, her initial recollections were fragmented, leaving law enforcement with very few tangible leads. However, the resilience of the victim and her family, combined with modern forensic breakthroughs, eventually pierced years of silence. Examining how this investigation unfolded reveals critical insights into how cold cases are solved when traditional physical evidence is initially insufficient.
The 2008 Attack and Initial Investigation
On the morning of September 19, 2008, Brittani Marcell was home in Albuquerque when an intruder forced entry. Armed with a shovel found near the property, the assailant launched a vicious attack that left Brittani with severe cranial fractures. Her mother, Diane Marcell, returned home shortly after and interrupted the attacker, who threatened her before fleeing the scene.
First responders rushed Brittani to the hospital, where she hovered near death for days. While she survived, the physical and psychological toll was immense:
- She spent months undergoing intensive neurosurgery, including procedures to reconstruct her skull using bone plates.
- She had to relearn how to walk, talk, and eat.
- She sustained permanent hearing loss in one ear and vision impairment in one eye.
- Retrograde amnesia wiped out her memory of the attack and the moments leading up to it.
Early police efforts stalled. Investigators canvassed the neighborhood, collected latent prints, and interviewed witnesses, but without a clear suspect or a cooperative memory from the sole eyewitness victim, the trail went cold.
The Breakthrough: Recovered Memory and DNA
Years passed while Brittani rebuilt her life through sheer determination. A major turning point occurred in October 2016—more than eight years after the incident. As part of her ongoing cognitive recovery, fragments of memory began to return. Brittani recalled interacting with a man named Justin Hansen at a local retail kiosk where she had previously worked. She remembered him making casual conversation and visiting her booth on multiple occasions prior to the assault.
Armed with this specific name, the Albuquerque Police Department reopened the case file. Investigators discovered that Justin Hansen lived relatively close to the Marcell family home at the time of the attack. Detectives conducted surveillance and managed to acquire a discarded item containing Hansen's DNA.
The New Mexico Department of Public Safety forensic lab performed STR DNA comparisons. The profile obtained from the crime scene matched the DNA collected from Hansen. This biological evidence bridged the gap between Brittani's recovered memory and hard scientific proof, giving prosecutors the foundation needed to secure an arrest warrant.
Trial, Sentencing, and Legal Aftermath
Justin Hansen was arrested in 2017. The arrest immediately drew public attention due to the bizarre contrast between Hansen's ordinary life as a father with no prior violent criminal record and the extreme brutality of the 2008 assault.
During the pre-trial phase, a judge initially granted Hansen release under GPS monitoring and house arrest, a decision that drew sharp criticism from law enforcement officials who viewed the conditions as lenient given the severity of the charges. However, as the legal process moved forward, the weight of the forensic evidence proved insurmountable.
In July 2018, Justin Hansen was sentenced to 18 years in prison after pleading guilty to aggravated burglary and aggravated battery. For Brittani Marcell and her family, the sentencing represented a definitive chapter of closure. In statements following the verdict, Brittani emphasized that the outcome validated years of personal hardship and proved that perseverance can lead to justice even when a case appears entirely cold. Later developments during his incarceration, including an inmate altercation captured while he served time, kept the case in true-crime media spotlights.

Frequently Asked Questions
How did Brittani Marcell eventually remember her attacker?
Brittani experienced spontaneous memory retrieval over eight years after the incident. Cognitive triggers allowed her to remember casual interactions she had with Justin Hansen at a retail booth where she worked prior to the assault, which she reported to detectives.
What kind of physical evidence linked Justin Hansen to the crime?
Investigators recovered discarded items belonging to Hansen to obtain a DNA sample. Forensic testing matched this DNA profile to biological evidence collected at the crime scene in 2008.
How long was Justin Hansen sentenced to serve?
In July 2018, a New Mexico court sentenced Justin Hansen to 18 years in prison following legal proceedings connected to the shovel attack.
Did Justin Hansen have a prior criminal record?
At the time of his arrest, investigators noted that Hansen had no prior violent criminal convictions, which initially surprised detectives investigating such a violent crime.
