Former NFL star Junior Seau had no alcohol or illicit drugs in his system upon committing suicide this year, nor did he exhibit any signs of brain damage.
According to the autopsy and toxicology reports released Monday by the San Diego County medical examiner, Seau's medical history was unremarkable.
His girlfriend, Megan Noderer, told police that Seau gave no indication that he planned to kill himself, making his decision to do so even more of a mystery.
When Noderer returned to their home May 2 after a morning workout, she found Seau in bed, dead of a gunshot to the chest from a .357 magnum revolver.
No note or "documents that were suicidal in nature" were found. The San Diego County medical examiner declared Seau's death a suicide the next day.
The 43-year-old was taking prescription medicines for orthopedic problems and insomnia, and was under the care of Chargers physician Dr. David Chao.
The former Oceanside and USC football star drank only "socially [and] did not smoke, and there was no history of illicit drug use," according to the report.
Seau "had an unremarkable medical history" and exhibited no "suicidal ideation or confirmed suicide attempt," Deputy Medical Examiner Dr. Craig Nelson wrote.
Brain damage among football players due to concussions has become a controversial issue in the NFL, where Seau was a star for the San Diego Chargers.
At the request of the Seau family, brain tissue was sent to the National Institutes of Health for more advanced investigation. May he rest in peace.
