A professional tennis referee charged with murdering her husband was physically uncapable of killing him, her lawyer has claimed.
Lois Goodman was arrested for the murder of her 80-year-old husband last week as she was preparing to work as a line judge at the US Open.
The 70-year-old has had two knee replacements, a shoulder replacement, suffers from rheumatoid arthritis, hearing loss and constant spinal pain and is awaiting another shoulder replacement, making her incapable of the murder says her lawyer Alison Triessl.
"It is physically impossible for her to have done this," Ms Triessl said.
The trial continues.
