The prosecution rested its case against Pamela Phillips on Friday morning after more than two weeks of testimony.
Phillips stands accused of paying another man to kill her ex-husband Gary Triano, who died in an explosion at La Paloma in 1996.
Triano had just finished playing golf and returned to his car when a pipe bomb exploded, killing him and destroying his car.
Prosecutors say Phillips paid Ronald Young $400,000 to kill her ex-husband so she could earn a $2 million life insurance benefit from his death.
The defense plans to begin its case Friday, bringing the first of a list of nearly 100 witnesses.
Their case is expected to into April.
