Los Angeles (CNN) -- A 70-year-old tennis line umpire accused of killing her husband with a coffee mug pleaded not guilty in a Los Angeles County court Wednesday morning.
A judge reduced Lois Ann Goodman's bail from $1 million to $500,000 after her lawyer argued the 70-year-old woman was not a threat to anyone.
Goodman was in New York preparing for the U.S. Open tournament when she was arrested last week and charged with murder in the death of her 80-year-old husband in California on April 17, authorities said.
She allegedly hit Alan Goodman on the head with a coffee mug and then stabbed him to death with its broken shards at their Woodland Hills, California, home, authorities said.
A preliminary hearing is set for October 3 to determine if there is enough evidence to try Goodman.
If convicted, she could be sentenced to up to life in prison.
