Dublin Couple Plead Not Guilty in Son-in-Law's Killing

A 77-year-old couple accused of killing their son-in-law in Dublin, California, have pleaded not guilty to murder charges. Shouyong Zhang and his wife, Shili Chen, face charges in the death of Jonathan McKinsey, a New York Times executive, according to ABC7 News.

McKinsey was reportedly involved in divorce proceedings and a child custody dispute with the couple's daughter when he died, ABC7 News reported. The source did not provide further details about the alleged shooting or the circumstances surrounding his death.

Zhang's defense plans to ask a judge to release him from custody, according to a statement an assistant public defender provided to ABC7 Eyewitness News on Monday. The defense cited concerns about Zhang's health and well-being while he remains in jail.

The assistant public defender said Zhang has no prior history of legal trouble and is showing signs of dementia. The defense intends to raise those concerns in seeking his release, according to the statement reported by ABC7 News.

Both Zhang and Chen have entered not-guilty pleas to the murder charges. The source did not specify whether the court had scheduled a hearing on Zhang's requested release or provide further details about the status of the criminal proceedings.
