Testimony began Tuesday in a murder trial against a man and woman accused of killing a man in a store parking lot nearly two years ago.

Richard Niles and Mokeia Hammond are charged with killing James Salter, 24.

Salter was shot and killed in the parking lot of the Myrtle Beach Best Buy in April, 2007.

Monday, Ervin Moore pleaded guilty to voluntary manslaughter and armed robbery in the case, and has agreed to testify against Niles and Hammond. He will be sentenced after the trial wraps up.

Richard Niles' mother was charged as an accessory, but was killed in an accident before the original trial was to begin.
