AN: So far, I think the most unrealistic thing about this story would be that they got fingerprint and DNA results came back as quickly as they did, but let's go with "Seattle PD have a super quick forensic lab" and they already had matches to compare them with.

Clarifications: Police are already certain in their minds that Arizona killed Meredith so they were really just interested in getting a confession out of her rather to make things a little easier. A text came from her phone sometime during the day telling Meredith to meet at her apartment after work so they figure she sent it either between surgeries or she somehow managed to send it while in surgery. This would mean Arizona killed Meredith sometime between getting out of work and before they got the 911 call. Meanwhile, Arizona seems more concerned with Callie than she is about proving her innocence at the moment. Hope that makes sense and clears some things up.

Chapter 4

It was a good thing Teddy had given Arizona a half hour because it had been a long time since she had picked any type of lock. Not since her teen years when she and Tim were constantly up to no good. It was surprising that Teddy even remembered those stories. However, now she was lose from her handcuffs and restraints and just had to wait for Teddy. She appreciated the few moments she had to wait because it gave her time to think about the days events. She had been going from surgery to surgery all day long. She had spotted Meredith early in the day working in the pit. Callie had had the day off. None of this information helped her figure out who had killed Meredith, but Arizona did decide that the first place to look would be Meredith's case files.

Teddy was punctual, interrupting Arizona's train of thought as she walked into the room holding a syringe. Arizona jumped from the bed and gave Teddy a quick a hug, grabbed the syringe and then started to head for the door.

"Wait," Teddy called after her. Arizona halted right before she reached to open the door. Teddy couldn't go through with this, and Arizona couldn't turn back now. She felt Teddy walk up to her, and she turned to face her. Teddy pointed at her own cheek.

"It can't look like I let you go," Teddy said. Right.

...

Arizona had the syringe poised in her hand, and the moment she stepped out of the room, she put a hand over the officer's mouth and plunged it into his neck. He struggled for a moment, and then passed out. She left him propped in his chair, with his magazine in his lap. There. He's just a guard who fell asleep on the job.

She was in an empty wing of the hospital which was proving much more convenient for escaping. She needed to get to her office, to her computer. So she quietly headed to the Pediatrics ward, taking cover when she came across people. She finally made it to office and quietly slipped in. She could tell the police had already been here because of the disarray. She left the lights off anyway, and logged onto her computer. She went through Meredith Grey's files, and quickly printed off any and all documents related to Meredith. She was grateful that her privileges hadn't been revoked yet. She grabbed everything off of her printer, and then changed into some extra clothes that she kept in her office. She slipped out of her office, out of the hospital, and quickly headed out into the cool night, and across the street to their apartment. She knew it was stupid to go back, but she felt like she needed to, that she had to in order to get a better grasp on what happened.

When she reached her floor she walked down the hallway and saw the yellow tape marking their apartment door. She slipped her key into the lock, opened the door and ducked below the tape to enter, before closing the door and locking it behind her. She needed to get in and out fast because who knew how long it would take for them to realize she was missing. She grabbed a flashlight and shined it on the blood. She could clearly make out where she had slipped. Then she saw another set of prints, feet just a little larger then her own. Callie. And there was another smaller pool of blood. That must be Callie's blood. However, it wasn't a very large amount. Not enough blood loss to kill someone. She could only pray that Callie was still alive.

She went into the bedroom. Blood was still everywhere. Arizona was transfixed on the bed. She could remember so vividly the way Meredith's face looked when Arizona turned her. It would always haunt Arizona. Then she remembered the bathroom. That's where the killer had been hiding. Arizona stepped in there and was instantly frustrated. She wasn't a detective, and coming back her gave her no knew clues as to where Callie could be. She felt foolish for thinking this would help.

Then she heard a click at the front door. She quietly exited the bathroom, and someone was in the living room. Definitely not a police officer. Was this the killer? Whoever it was, was looking through the stacks of files she and Callie kept in their living room. Arizona then panicked as she noticed the files she had just printed off at the hospital sitting on the kitchen table. The intruder noticed them too as they headed over to them, and skimmed through. Then she saw a gun get pulled. The intruder, she was feeling more confident that this was the killer, headed towards the bedroom. Arizona shrunk back into the shadows and behind the door. Right as he passed through the doorway, they both heard the sound of sirens. No doubt the police had discovered that Arizona had escaped. However, the sirens also distracted the intruder, and Arizona quickly pushed the door into them, knocking them off balance and then she knocked the gun out of their hand.

She got her first glimpse of the killer, but couldn't identify them in the darkness as they were wearing a hoodie and ski mask. They quickly went to attack Arizona and landed a punch to her face sending her reeling backwards. They went to leave, but Arizona grabbed them pulling them back into the room. Maybe they'd kill her, but if she could keep them here long enough for the police to find, maybe they would be able to find Callie. The intruder pushed her off, and went to reach for the gun, but she stepped on their hand making them cry out in pain. Definitely sounded male. She pushed him backwards, and he scrambled and began to run away, she went to grab the gun and then aimed towards him, but he had excited the room far too quickly. She grabbed the papers she printed on Meredith and gave chase out of the apartment, out to the stairwell, she followed him down the stairs, but he was too fast, she was losing him. He made it out to the street while she was a few floors up, and when she made it to the doors she couldn't open them. He had locked her in.

She tried ramming her shoulder, but all that did was cause severe pain. "Fuck!" She yelled, though it was more about losing him than it was about the pain. She ran back up to the second floor, entered the hall of apartments and knocked on the first door she saw. It opened quickly. Arizona pointed the gun at Mr. Jefferson, and he stood there is shock.

"I'm really sorry about this. Inside," she ushered him inside via gunpoint. He was completely silent and was shaking. "Get your duct tape," she followed him as he grabbed tape. "Have a seat." He did so, and she quickly taped his mouth shut, his hands together, and taped his body and legs to the chair. "I'm sorry, I'm sure the police will find you soon, but I'll call them later and let them know to make sure," she said while grabbing his cell phone, an old flip phone, "I'm also taking your car," she grabbed his keys. "Sorry again." This time she headed to the opposite stairwell, and made her way to the parking lot, there was a police car headed over toward the apartment complex, but she found Mr. Jefferson's car quickly and slipped inside. She exited the opposite side of the parking lot that the police entered and made her hasty get away. She needed to find Callie, but had no idea how.

AN: Don't know how realistic a break out it is. Suspend reality a little people, since I guess the police didn't really consider Arizona a real threat.
