We knew that the East Bay couple accused of murdering their son-in-law "in concert" with one another had obtained separate defense council. And now it looks like the wife is trying to blame it all on the husband.Curtis Briggs, the attorney for 77-year-old Shili Chen, now asserts in a court filing ah ead of a November 4 bail hearing that his client should be freed because she had nothing to do with the killing of son-in-law Jonathan McKinsey. Her husband, 77-year-old, Shouyong Zhang, was "fixated" on McKinsey and kept her "in the dark" about his plans to shoot McKinsey, according to the court filing, per the California Post. And, Briggs says that Chen was told to bring a gun because they were going to a shooting range, and that after Zhang had already fired the fatal shot that killed their son-in-law, she only got out of the car "to protect her husband from what she feared was an assault by Mr. McKinsey."Witnesses and police have suggested that the couple "took turns" shooting McKinsey on September 26 and did so "in concert." Briggs earlier told reporters that the elderly couple feared for their lives and that McKinsey had hired a hit man to kill Chen, specifically.But now the strategy appears to be to claim that Chen was only along for the ride, and that her husband was solely responsible for the murder.As the Chronicle notes, Briggs's motion acknowledges that Chen also fired her gun. Police reportedly found 18 shell casings at the scene, but it seems that many of those were from Zhang's gun. According the the motion, Zhang exited the car, which was driven by Chen, around 3:05 pm, approached McKinsey, and shot him, continuing to do so for about 10 seconds before Chen exited the car. She then fired her own gun at McKinsey and walked away, and Zhang continued to shoot.The motion suggests both that Zhang has been suffering from "advanced stages of dementia," and that he told Chen to drive to the park where the shooting occurred but did not speak to her otherwise before or after the shooting took place.Briggs appears to be trying to clear his client of the special circumstance of "lying in wait" that was added to the murder charge, because that enhancement allows the court to hold her in custody without bail, as the Chronicle reports.Briggs has earlier told the court that his client is frail and may not even survive her incarceration pending trial. Both suspects are being held at Santa Rita Jail.Chen and Zhang are the parents of 46-year-old Candice Jang, who was married to McKinsey for about 15 years. Prior to or around the time of their marriage, McKinsey transitioned from female to male, and according to earlier court filings by McKinsey and Jang as they were going through a contentious divorce, his being trans was an issue for Jang and her parents from the start.Jang and McKinsey each had filed restraining orders against the other, claiming abuse of each other and the children. And in McKinsey's filings, he alleged that Chen had once called both him and her grandchild "disgusting queer" and other names.At the time of the shooting, McKinsey had recently been granted visitation rights with his three children, ages 3, 5, and 7. The children had been at the Dublin park with their father before the shooting took place, but had left, according to court documents.Chen has been described as a full-time nanny for the children, living much of the time in their Dublin home. McKinsey moved out of the home last December.Dublin police executed a search warrant at the home in the days after the shooting, but they have not suggested any wrongdoing on the part of Jang.Previously: Defense Now Claims Slain East Bay Engineer Hired Hit-Man to Kill His Elderly Mother-In-Law ...read more read less
