NYT engineer killed by in-laws during supervised visit with kids at Dublin park, prosecutors say

Published October 19, 2026 2:02 PM MST

An elderly couple accused of gunning down their son-in-law at a crowded Dublin park allegedly carried out the killing during a supervised visit between the victim and his children, prosecutors revealed Monday.

The details emerged during a plea hearing for Shili Chen and her husband, Shouyong Zhang, both 77. The couple pleaded not guilty to first-degree murder charges in the Sept. 26 death of Jonathan McKinsey, 40. The murder charge includes a special circumstance allegation of lying in wait.

Park shooting

The backstory:

McKinsey, the head engineer of games player experience for The New York Times, was shot and killed at the Dublin Sports Grounds.

Prosecutors alleged Chen and Zhang showed up during McKinsey’s scheduled visit with his three children and took turns shooting him.

McKinsey’s supervised visits were required to take place in the presence of a social worker, and one was there that day.

Elderly couple lay in wait to kill son-in-law at Dublin park: DA

An elderly couple accused of fatally shooting their son-in-law at a crowded Dublin park in broad daylight has been charged with murder, though authorities have not released a motive.

Police arrested Zhang and Chen nearby shortly after the incident.

Investigators said they recovered two handguns and obtained surveillance video showing the couple killing McKinsey.

Defense claims fear of victim

What they're saying:

Curtis Briggs, defense attorney for Chen, maintained that his client is not guilty. Briggs said the couple went to the park because they believed McKinsey was abusive and feared he would harm their grandchildren.

According to Briggs, Chen and Zhang began carrying firearms in March because they were fearful of their son-in-law. Briggs alleged McKinsey had threatened to kill the couple on three separate occasions, including one incident in which he allegedly threatened to hire a hit man to kill them. 

Custody battle

The killing happened amid a contentious divorce and custody dispute between McKinsey and his wife. While McKinsey's wife had previously been granted a temporary restraining order against him, McKinsey was recently granted supervised visits with their children.

Chen and Zhang had lived with McKinsey and their daughter prior to the separation and Chen was a live-in nanny for the family.
