At 2:27 a.m., my mother called from a police-station bathroom and whispered, “Honey, Dana hurt me during an argument, and your brother did nothing. Now they’re claiming I’m mentally unstable and blaming me for everything.”

“You should persuade her to cooperate,” she told me. “This can still remain private.”

Michael added, “We’re still family.”

A steady voice came from behind me.

“No.”

Mom stood there with her wrist supported, but her posture was firm.
