JOHANNESBURG — The murder trial of Oscar Pistorius resumes today after one month during which mental health experts evaluated the athlete to determine if he has an anxiety disorder that could have influenced his actions on the night he killed girlfriend Reeva Steenkamp.

Judge Thokozile Masipa was expected to receive the conclusions of a panel of one psychologist and three psychiatrists who were instructed to assess whether the double-amputee runner was capable of understanding the wrongfulness of his act when he shot Steenkamp through a closed door.

The assessments of the panel could determine whether Pistorius should be held criminally responsible and affect the judge’s deliberations on a verdict or, in the event of a conviction, the severity of the sentence.

Prosecutor Gerrie Nel has alleged that Pistorius, 27, killed the model after an argument and has portrayed him as a hothead.
