A California couple is in trouble with the police.

They shot their son-in-law dead on Saturday.

It happened in a public park.

The killing came days before a court meeting about a divorce.

The couple are Shili Chen and Shouyong Zhang.

Both are 77 years old.

They were going to court on Wednesday.

Their daughter is Candice Jang.

She could not be reached.

But she came to the Wednesday hearing by video.

Jonathan McKinsey was 40 years old.

He worked on games for The New York Times.

He was shot in a parking lot.

The parking lot is at a sports center in Dublin.

Dublin is east of San Francisco.

A police officer was driving nearby.

He saw McKinsey on the ground.

Other people called 911.

They showed the officer the couple.

The couple were still near the place.

Dublin Police Services said this.

Court papers show the divorce was full of fights.

There was also a fight about who keeps the three young children.

Last year, both McKinsey and Jang asked for restraining orders.

They said the other one hurt them.

This went back more than ten years.

McKinsey was transgender.

He said Jang and her parents said mean things to him.

He said they hurt him with their hands too.

He said this was about his change of gender.

He also said Zhang hit him in the chest.

This happened while he was getting better after surgery.

McKinsey was arrested last October.

Police said he hit their oldest son.

They charged him with child abuse.

He said he did not do it.

In court papers, he said his wife set a trap for him.

He was let go but had to finish 12 parenting classes.

When he was killed, he was out on bail.

He was trying to join a mental health program.
