Jurors in the case of 71-year-old Charles Black were picked Monday in all-day process that ended late in the afternoon.
Prosecutors say in April 2011, Charles Black hit Lisa Black in the head with a rock, then shoved her off Maiden Cliff in Camden.
Police say the couple was at odds over a $4 million inheritance from her father.
She survived the fall.
Charles Black is charged with attempted murder as well as multiple assaults.
The two have since divorced.
