Wendy had been found and brought in, forcefully, to the local police when Booth had been immediately informed.
"Wendy, I thought I said stay local." Booth smiled, Dr. Brennan following him into the interrogation room.
"I thought you meant in the country." She said feebly, looking nervous.
"You know what I meant." Booth replied. "You should know, we've arrested Mrs. Garcia with charges of murder, and breaking and entering." Wendy visibly flinched. "We also know that you two are involved, as well as that you both killed Tony." She stayed silent. "You will be charged as an accessory to murder, but you're lucky. You're girlfriend will probably be given life."
"You can't do that! It wasn't her idea!" She shouted.
Booth lowered himself to eye level with Wendy. "Why don't you tell me what happened?" She stayed silent. "Wendy, you're both going to prison, we have evidence and motive. Trust me, judges and jurors are a lot happier with 'guilties' to 'not guilties'. Sentence is shorter."
She broke her silence. "Tony was a bastard, he got what he deserved."
"So he hit you?" Brennan had seen the scorn in her eyes before.
"Not me." She kept her stare low.
So, Mrs. Garcia." Booth concluded, sitting in the opposite chair.
"He went home, always drunk after he had lost money and he would just keep hitting her over and over." Tears slipped down her face, terrified by the brutality.
"So how did you two meet?" Booth asked.
"Betty and I met in an abusive partners website, my old girlfriend had hit me too, and I was still recovering. We started talking everyday and then we finally met. I was in love instantly." She smiled nostalgically. "And she loved me. We needed to be together, but Betty… she was too scared to leave Tony, she kept saying he'd kill her."
"So you suggested you'd kill Tony first." Booth smiled, everything coming together.
"I posed as his girlfriend, keeping him close. On the night we went back to my motel room, Betty had given me the poison and I killed him. I had taken the acrd to frame Brithe just in case, I didn't think anyone would find a buried body in the forest of Brookside." She nodded her head. "We buried him together."
"I think we got everything we need. The state can handle the rest." And then without even looking back at Wendy, they left.
Case closed.
