Rebecca Bowers Sears, 41, and her son, Christopher Sean Bowers, 20, pleaded not guilty to murder, armed robbery and burglary charges at an arraignment in the Columbia County Justice Center.
Mrs. Sears, of 227 Hot Spring Drive, and Mr. Bowers, of the 4000 block of Briarwood Drive in Martinez, are accused in the fatal beating of Laverne "Kay" Parsons, Ms. Sears' next-door neighbor and co-worker, March 25.
District Attorney Ashley Wright has said she plans to seek the death penalty.
A bond hearing had also been scheduled Wednesday, but it was postponed while defense attorneys review paperwork, said Victor Hawk, Ms. Sears' attorney.
Mr. Hawk said a date for the postponed bond hearing hasn't been set.
Attorneys and prosecutors will meet July 7 to hear motions. No trial date has been set.
