She stared pointedly at the snow. Bobby shut up.

“What about birth father?” D.D. tried. “If Brian Darby is the stepdad, then where’s Sophie’s birth father and what does he have to say about all this?”

“No birth father,” Bobby reported.

“I believe that’s biologically impossible.”

“No name listed on the birth certificate, no guy mentioned around the barracks, and no male role model visiting every other weekend.” Bobby shrugged. “No birth father.”

D.D. frowned. “Because Tessa Leoni didn’t want him in the picture, or because he didn’t want to be in the picture? And oh yeah, in the last couple of nights, did those dynamics suddenly change?”

Bobby shrugged again.

D.D. pursed her lips, starting to see multiple possibilities. A birth father intent on reclaiming parental rights. Or an overstretched household, trying to juggle two intense careers and one small child. Option A meant the biological father might have kidnapped his own child. Option B meant the stepdad—or birth mother—had beat that child to death.

“Think the girl is dead?” Bobby asked now.

“Hell if I know.” D.D. didn’t like to think about the girl. A wife shooting her husband, fine. A missing kid … This case was gonna suck.

“Can’t hide a body in the ground,” she considered out loud. “Too frozen for digging. So if the girl is dead … Most likely her remains have been tucked somewhere inside the house. Garage? Attic? Crawl space? Old freezer?”

Bobby shook his head.

D.D. took his word for it. She hadn’t ventured into the house beyond the kitchen and sunroom, but given the number of uniforms currently combing through the eleven hundred square foot space, they should’ve been able to dismantle the structure board by board.

“I don’t think this has anything to do with the birth father,” Bobby stated. “If the birth father was back in the picture making noise, those would be the first words out of Tessa Leoni’s mouth. Contact my rat bastard ex-boyfriend, who’s been threatening to take my daughter from me. Leoni’s said no such thing—”

“Because the union rep has shut her down.”

“Because the union rep doesn’t want her to make statements that incriminate herself. Totally fair game, however, to make statements that incriminate others.”

Couldn’t argue with that logic, D.D. thought. “Fine, forget birth father for a second. Sounds like the current household was dysfunctional enough. To judge by Trooper Leoni’s face, Brian Darby is a wife beater. Maybe he hit his stepdaughter, too. She died, Trooper Leoni came home to the body, and they both panicked. Stepfather has done a terrible thing, but Trooper Leoni let him, making her party to the crime. They take the body for a drive and dump it. Then get home, get into a fight, and the stress of the whole situation leads Tessa to snap.”
