Former NFL linebacker Junior Seau had no alcohol or illegal drugs in his system when he shot himself in the chest back in May, and an initial examination of his brain showed no apparent damage from his years of playing football. As such, the cause of his death has been ruled as a suicide — this according to the San Diego medical examiner.

According to the toxicology reports released on Monday, filed by San Diego County medical examiner Craig Nelson, Junior Seau died of a self-inflicted gunshot wound to the chest from a .357 caliber revolver on May 2, 2012. The report also shows “No alcohol, common drugs of abuse, or other medications were detected.”

However, a small amount of Zolpidem (also known as ambien) and Naproxen (an anti-inflammatory) were detected in his system, but the medical examiner said that the test results were “consistent with therapeutic use.”

Seau’s girlfriend, Megan P. Noderer, told the police that 43-year-old Junior Seau had given no indication that he planned to commit suicide, this according to the “investigative narrative” attached to the autopsy report.

When Megan returned to the home in Oceanside on May 2 after a morning workout at a gymnasium, she found Junior Seau in bed, dead of a gunshot wound to the chest. No suicide note or “documents that were suicidal in nature” were found.

The report also added that 6-foot-3, 275-pound Junior Seau, a star at Oceanside High, USC and then at the National Football League, was taking prescription medicine for orthopedic problems but only drank “socially (and) did not smoke, and there was no history of illicit drug use.”

After his suicide, Seau’s family requested that his brain tissue be sent to the National Institutes of Health for more complete testing. Brain damage among football players has become a controversial issue in the National Football League, where Seau was a star for the San Diego Chargers and other teams.

The autopsy and toxicology results were released after San Diego news agencies requested them as public documents. However, the officials at the county medical examiner’s office — out of respect for the family of Junior Seau — declined to discuss the reports.

Megan Noderer–the girlfriend of future NFL Hall of Famer Junior Seau–was hysterical as she called 911 following her discovery of the NFL great’s body last Wednesday morning.

The Hollywood Gossip reported that Noderer found the body of her beau at his Oceanside, Calif., home with a bullet wound in his chest. She was so hysterical during the 911 call that she could barely speak.

Megan Noderer frantically tells the 911 dispatcher that the 43-year-old athlete wasn’t breathing when she arrived. She also managed to describe Junior Seau as apparently having shot himself “in the heart.”

Authorities responded to Noderer’s 911 call and attempted to revive Seau. However, Seau was soon pronounced dead on the scene. Police have ruled his death a suicide.

According to his family, Seau did not show any signs of depression before his death. They have donated his brain for concussion research.

The tragic suicide of Junior Seau has restarted a debate on how pro football inflicts lasting brain injuries to its players.

Ex-NFL star Junior Seau was confirmed dead by the Oceanside, CA police this Wednesday morning. He was 43 and apparently committed suicide. According to Gossip Cop, cops responded to a 911 call placed around 9:35 a.m. PT by his girlfriend. Paramedics failed to revive Seau.

Oceanside police said the former National Football League star died in an apparent suicide via a self-inflicted gunshot to the chest. They are still investigating his death and have noted the presence of a handgun near the body of Junior Seau.

If it proves to be suicide, it would not be Seau’s first attempt to take his own life.

Two years ago, he was arrested on suspicion of domestic violence against a 25-year-old girlfriend. After his release, Junior Seau drove his Cadillac SUV off a cliff in California. Seau later claimed that that he fell asleep at the wheel and it was not a suicide attempt.

The late Junior Seau leaves behind three children. TMZ reported that Seau supposedly sent text messages to them on Tuesday that told his kids that he loved them.

Seau’s family became absolutely distraught when they finally arrived on the scene around noon. His mom, Louisa Seau, begged, “Show your love to my son,” and prayed to asked God to “take me” instead of Seau.

“Honor his last day,” his sister, Annette Seau, asked the media, “And give us some kind of peace and privacy.”

Nearly 250 relatives, friends, and fans will be holding a prayer vigil around the Oceanside, CA home of Junior Seau.
