In the complaint, Rentz and Lister allege that Bradley Cooper had been having an affair and that in the months leading up to Nancy's death, he'd been yelling at Nancy and belittling her in front of the children.

In the complaint, Rentz and Lister say that in a few months ago Bradley Cooper had removed the children's passports from Nancy Cooper's vehicle, essentially prohibiting her from moving to Canada with the children.
They also claim Bradley Cooper was withholding money from his wife, and Nancy Cooper had to borrow money from her family to buy groceries for her and the girls.

The judge also ordered Bradley Cooper to turn over the passports of Isabella, 4, and Gabriella, almost 2, so they might attend their mother's funeral in Canada. Later this month, a judge will consider a request for Rentz and Lister to care for the children more permanently.

Rentz and Lister said in the custody complaint that Bradley Cooper had been having an affair with another woman. They also say that Bradley Cooper threatened suicide earlier this year and had tried to kill himself as a teenager.

I assume they have seen the petition to be able to state these things in the manner they did.
