In October 2013, two-year-old Tyrese Ruffin, the biological son of former NFL running back Adrian Peterson, died from severe injuries caused by physical abuse in Sioux Falls, South Dakota. The perpetrator, Joseph Robert Patterson, was convicted in 2015 of second-degree murder and sentenced to life in prison without parole.
Overview of the October 2013 Incident
In October 2013, news broke across national media outlets that the two-year-old biological son of Minnesota Vikings running back Adrian Peterson had been hospitalized in critical condition. The child, identified as Tyrese Robert Ruffin, had suffered catastrophic head injuries while under the care of Joseph Robert Patterson, who was dating the child's mother, Ashley Ann Doohen, in Sioux Falls, South Dakota.
On October 9, 2013, emergency first responders were dispatched to an apartment building in Sioux Falls after Patterson placed a 911 call claiming that the toddler was choking on food. Upon arrival, medical personnel discovered the child unresponsive and exhibiting symptoms far more severe than asphyxiation. Tyrese was immediately rushed to Sanford Children's Hospital in Sioux Falls, where doctors determined he was suffering from internal brain swelling, subdural hematomas, and severe blunt force trauma consistent with violent physical abuse.
After two days on life support with non-recoverable brain activity, medical professionals and family members made the painful decision to remove life-sustaining care. Tyrese Ruffin was pronounced dead on October 11, 2013.
Relationship Context and Paternity
At the time of the incident, Adrian Peterson was one of the most prominent athletes in the National Football League, having won the NFL Most Valuable Player (MVP) award for his 2,097-rushing-yard season in 2012. However, Peterson had only recently learned of his biological paternity regarding Tyrese.
Peterson had not lived with the child or mother in South Dakota, but had been in the process of arranging travel to Sioux Falls to assist with financial support and build a formal parental relationship. Peterson arrived at the hospital in Sioux Falls shortly before the toddler was removed from life support, marking one of the few times he was able to be by his son's bedside.
Criminal Investigation and Arrest of Joseph Patterson
Local law enforcement agencies, led by the Sioux Falls Police Department and Lincoln County authorities, launched a criminal investigation immediately following the emergency room admissions report. Medical examiners and pediatric trauma specialists evaluated the physical evidence, concluding that the severe brain damage could not have resulted from a simple fall or choking episode as claimed by the caregiver.
Joseph Robert Patterson, then 28 years old, was taken into custody shortly after the emergency call. Prosecutors initially charged Patterson with aggravated assault and aggravated battery against an infant. Following the child's death on October 11, state prosecutors upgraded the charges to include second-degree murder and manslaughter.

Forensic Findings and Prosecution Claims
During preliminary hearings, prosecutors detailed the forensic evidence assembled by state pathology experts. Key findings included:
- Blunt Force Brain Trauma: Medical experts documented multiple areas of impact to the child's skull and severe brain swelling caused by force far exceeding domestic accidents.
- Inconsistent Statements: Investigating officers noted that Patterson's timeline and explanation of a choking episode contradicted the clinical physical findings.
- Pattern of Injury: Radiographic imaging and physical examinations showed evidence of injuries indicative of physical abuse occurring prior to the final fatal event.
Trial, Verdict, and Sentencing in South Dakota
The criminal trial of Joseph Robert Patterson took place in Lincoln County Circuit Court in Canton, South Dakota, in September 2015, nearly two years after the fatal event. The prosecution was led by state attorneys seeking maximum penalties under South Dakota criminal law.
Evidence Presented at Trial
Over the course of the multi-week trial, the prosecution presented extensive medical testimony. Board-certified pediatric intensivists and forensic pathologists testified that the severe neurological injuries Tyrese sustained required extreme physical force, equivalent to a high-speed vehicle collision or a fall from a multi-story building.
The defense contended that the child had choked on a snack, leading to oxygen deprivation and cardiac arrest, and argued that resuscitative efforts by Patterson had inadvertently caused minor bruising. However, prosecutors effectively countered this defense by bringing in expert witnesses who demonstrated that the distribution of internal head injuries could not be produced by Cardiopulmonary Resuscitation (CPR) or simple airway obstruction.
The Verdict and Sentence
On September 29, 2015, after deliberation, the Lincoln County jury rejected the defense's arguments and returned a guilty verdict on multiple counts:
- Second-Degree Murder (SDCL ยง 22-16-7)
- Aggravated Child Abuse (SDCL ยง 26-10-1)
- Second-Degree Manslaughter (SDCL ยง 22-16-15)
In November 2015, Circuit Court Judge Bradley Zell sentenced Joseph Patterson to the statutory maximum: life imprisonment without the possibility of parole. Under South Dakota law, second-degree murder carries a mandatory life sentence, ensuring the offender remains incarcerated indefinitely without eligibility for early release.
