South African paralympic sprinter Oscar Pistorius was not mentally disabled when he shot his girlfriend to death, according to a psychiatric assessment, CNN reports.

After a month-long break for the evaluation, the trial resumed today and the results of the assessment were revealed in court.

An independent panel of doctors determined that Pistorius did not suffer from a mental defect or mental illness at the “time of the commission of the offense that would have rendered him criminally not responsible of the offenses charged.”

Pistorius was capable of appreciating “the wrongfulness of his act,” the evaluators said.

If doctors had found Pistorius mentally incapacitated during the shooting, the trial would have ended in a verdict of not guilty by reason of mental illness, CNN reports.

Pistorius, 27, is charged with murdering girlfriend Reeva Steenkamp, a 29-year-old model and law school graduate, in his home on Valentine’s Day, February 2013.

Pistorius admitted to shooting Steenkamp through a closed door, saying he mistook her for an intruder. He pleaded not guilty.

The prosecution said Pistorius argued with Steenkamp before killing her.

A psychiatrist said he has suffered from generalized anxiety disorder since infancy, partly due to the amputation of his lower legs. The disorder gave Pistorius excessive concerns about security, Dr. Merryll Vorster testified on May 12.

Prosecutor Gerrie Nel asked the judge to require psychiatric tests, considered an unusual move since Pistorius’ legal team was not mounting an insanity defense, CNN legal analyst Kelly Phelps said.
