PRETORIA, South Africa (AP) — The defense team for Oscar Pistorius plans to close its case after its last witness, a physician who has treated the athlete, completed his testimony at the murder trial on Monday, a lawyer said.

The end of testimony signals a new phase in the months-long trial of Pistorius, who killed girlfriend Reeva Steenkamp in his home in what he has described as a mistaken shooting. It is expected to lead to a break during which the defense and prosecution prepare final arguments as the high-profile legal battle moves toward a conclusion.
