Coyle pointed to the car photo. “Vintage Mercedes. Plate’s not visible. I’m working on narrowing down the year, and then I’ll try to match it with the California state DMV database.”

“What kind of car does Partridge drive?” Frames asked.

Rivas shrugged. “Two years ago, a Nissan 240Z.”

“We should look at his friends’ cars,” Coyle said.

“Does a guy like that have friends?” Frames asked.

“Martin, check names of associates in Partridge’s file,” Mahler said. “While you’re at it, you might look at probation reports to the court for sentencing, and you can pull reports of stolen cars.”

“The security camera footage from the two residences in the Violetti neighborhood was a bust,” Frames said. He held up a plastic evidence bag. “Also, we sent a canine team back to the trees where the dog walker said she was pulled. They found this scarf. Obviously, we don’t know if it belonged to the victim.”

Eden took the plastic bag from Frames. “Color matches her outfit. And it’s got a label we can check.”

Rivas laid his hand on a pile of folders in front of him. “Eddie, I started pulling files, like you said, of guys we picked up the last couple years for physical assault. I’ve got six. You remember Robert Temple? He’s out again.”

Mahler took the folders. “Okay. I’ll go through them.” He stared at the photo of the victim on the whiteboard.

“By the way,” Rivas said, “Peña’s lawyer emailed me. Apparently Peña wants to see me. Tomorrow morning, first thing.”

“Be careful with that. Let one of the ADAs know you’re going.”

Mahler took down the photo of the victim’s body from the whiteboard. “There’s something odd about this. This morning Daniel asked why she was left in the park. But it’s more than that. She was killed somewhere else and left here. Normally, if you laid a body on a bench, you’d put it on its back, right? Or, maybe facedown.”

Mahler held the photo toward the others. “Look at this. She’s lying on her side.”

Coyle shook his head. “What’re you saying?”

“She was arranged,” Eden said.

Mahler looked at her. “Yes. It was intentional.”

“I don’t get it,” Frames said. “What’s it accomplish?”

“I don’t know. But someone wrapped her in a blanket and laid her on her side.”

“It might have been done for her or for whoever found her,” Eden said.

Frames snorted. “How’s it help her? She was already dead.”

“It’s called ‘undoing.’ It’s where a killer tries to psychologically undo a crime, to return the victim to a normal state.”
