“No. There are hundreds of hours of footage, starting from November. A lot of it is whatever you can see while Maya drags Ellie around the apartment. Or in the car. It’s mostly life from the viewpoint of a four-year-old.”

“Tell us again about the part where Rooney shows up,” Joe said.

“It might not even be him,” Letty repeated. “It’s a guy in a knit cap and a puffy jacket. He walks into the apartment, and Tanya looks a little surprised, but then happy to see him. They kiss, and Tanya points out Maya, who’s across the room holding Ellie, which is why it’s hard to make out the guy’s face, or hear any of what the grown-ups are saying. Then, Maya freaks out and runs upstairs, taking Ellie with her. And that’s it. I watched more of the footage after that, but the mystery man doesn’t show up again.”

“And you can’t hear what Tanya and the man are talking about?” Agent Hill repeated.

“No.”

“Where’s this camera now?” she asked.

Letty fetched the camera and thumb drive Sierra had given her from her nightstand and placed it in the FBI agent’s hand. “This is it. Can you copy it and return it to me?”

Vikki nodded. “Okay. We’ll get it back to you. When was the most recent video shot?”

“February twenty-eighth was the last date,” Letty said. “I probably only got through a couple weeks’ worth before I finally fell asleep last night.”

She looked down at her hands, and then up at Vikki Hill. “I think the battery must have run down … before Tanya was killed. I fast-forwarded to the end, which takes place three days before. It’s nothing special. She takes Maya to the dentist, and the pediatrician. Tanya was getting ready to move to LA, you know, so she wanted to have all Maya’s records for when she started school out there.”

Letty’s eyes filled with tears. “I know my sister wasn’t a model mom. She could be self-involved and impetuous and so, so self-destructive. And yes, she struggled with drugs and alcohol. She and Evan had these awful knockdown fights, right in front of Maya. There’s one on the video, and it was so tough to watch. But she loved her daughter. Really loved her. And she was trying to do what was best for Maya. To get away from Evan, and start over.”

Letty found herself remembering the last bit of footage she’d watched the night before. The video showed Tanya giddy with excitement in anticipation of the move. She found herself choking up as she described the video.

“They went to Old Navy. It was snowing outside. She bought Maya a bathing suit, because the house she was going to rent out there has a pool.…”
