Oscar Pistorius' attorneys are going the extra mile to see that their client receives the best possible defense ahead of his murder trial, which is slated to begin in March.

Pistorius' attorneys are working with American forensic analysts to help counteract evidence presented from the prosecution, the Associated Press said.

"A team of forensic specialists from the United States is currently in the country working with Oscar's defense team," spokesperson Anneliese Burgess said. "We don't want to go into great detail about this except to stay it is very standard practice to work with specialists from various fields in preparation for any trial."

Pistorius faces 25 years to life in prison if convicted of murdering his girlfriend, Reeva Steenkamp, in a horrific and fatal Valentine's Day shooting in the South African capital of Pretoria. Steenkamp was visiting Pistorius for the night when he fatally shot her through the bathroom door. The double amputee Olympic sprinter has admitted to shooting her but said he mistook her for an intruder. Meanwhile, prosecutors are not convinced. The prosecution may stress that some witnesses could hear the couple arguing in the moments leading up to the shooting or that Pistorius has a history of being reckless.

The 26-year-old Pistorius could also face a lesser murder charge that would hold a minimum sentence of 15 years, and if things really go his way then he could look at a five-year prison term if convicted of culpable homicide or negligent killing.

Pistorius has stayed out of the public realm since the incident in February. Besides court appearances and brief sightings on the track, the former South African icon has been focusing on his trial. He also has not posted to his twitter account since the shooting.
