A/N I don't own anything

As we stand in Detective Benson apartment I feel sick to my stomach at the amount of blood on the walls, the broken furniture, the blood on the carpet and finally Olivia's lifeless bruise and bloody body. From what the Medical Examiner is saying she fought to stay alive and if she had to speculate the cause of death it would be one of the fifteen stab wounds in her body or blood loss.

I look around and see her closet open and blood splatter on the wall so I call Cragen over and show him and we document it before investigating further and I find her laptop and it's open. No blood on it or anything it was hidden in a box under a blanket like someone did that on purpose. Cragen looks at it and shuts it and places it in an evidence bag.

We finish with our crime scene and head back to the precinct. As we walk in I see Barba sitting in a spare chair looking at his phone. Cragen walks up to him and says "We will need a warrant sometime. But it will be a hard case. Detective Benson has been murdered in her apartment."

Barba "What? How? When? Let me know what you need and I will try to get it."

Cragen "thank you…"

Barba walked away with his head down like he was crying.

I say "Cragen, We need to get her justice because out of all of us she did not deserve this. She put her heart and soul into this precinct and helping those victims get justice"

Cragen "I know…"

That was the end of the conversation. I realized everyone was looking at me and made me think about what we do now. I know I mean Olivia would help give orders. Then I thought she is dead now. I am the senior Detective.

I say "Rollins go look through her locker in the female locker room to see if there is anything helpful. Amaro takes Munch and goes through files and looks at her cases and sees anyone recently got released or escaped. I will go through her desk."

I see Cragen do a sad smile and he nodded and got out his cellphone to call someone. I start going through her desk about one hour later I find a paper that says camera with an email and password and website. So I go to my desk and sit down. I log on and go to the website and try it. I see right into her apartment. I see live footage. I realized this may be the key to getting Olivia's killer. I stand up and run to Cragen's office who is looking at some reports and cases of Olivia's that got out or parole.

"Cragen, I found something…"

He gets up and comes to my desk and sees what I see. He looks at me and says "Can you rewind the video to see if we can see the murder or what led up to it and maybe the killer."

Amanda walks in and sees everyone staring at me. I rewind to the time she gets off work and watch her walk in with groceries set on the counter. She says "hello Bri." I feel my eyes trying to water as I hear her voice. Then we see a gun to her head and her starting to fight. I realize this may be the beginning of the last fight of her life she lost.

We continue watching and see a familiar face. I pause it and look at Cragen and say "Is that…"

Amanda "William Lewis"

Nick is on the phone with Barba telling him to get to the precinct.

Munch "who is Lewis?"

"John, he was a suspect who got a mistrial and is out on bail."

Barba walks in fifteen minutes later. I show him the footage and we finish all of the footage and by the end we all witness the sexual assault and murder of Olivia Benson. Barba got us our warrant. We got a call from CSU and got some more evidence that likes him but the most important one is the unfinished email from her.

Dear Donald Cragen, John Munch, Odafin Tutuola, Amanda Rollins, Nicolas Amaro, Rafael Barba,

I love you all. As you may know I have two days off but what you don't know is that these days may very well be my last days. I am back tomorrow and nobody has come to check on me. I mean that is not unusual but doesn't mean that I wasn't hoping. You see this is my last attempt to get either help or help get me justice. An email to you guys to figure out how to assist. You see as I am typing this I am hiding in my closet as Mr. William Lewis is yelling and screaming for me to come out so he can kill me.

I am typing as fast as I can to get you some information but who knows I may not finish this email. I have to properly write a letter or email because childhood bullshit that I will explain if and that is a big if I get out of here alive. I have never in my life have fought so hard to stay alive. I will never figure out why people want to kill or even sexual assault others.

Well if this does reach you and I am found dead either in my apartment or in a ditch somewhere that is if you even find me. Turns out everything we know about this guy just barely scrapes the surface of what he is capable of. I have cameras. I think I have the password and stuff in my top left drawer in my desk at work. There is a timeline and evidence you can use.

Please protect each other. This guy doesn't play games. Trust me you do not want to be on this end….

It took us two days to find Lewis and arrest him. He was sentenced to 25 years to life in prison. I was so happy to hear the life sentence for him. We got back to the precinct and I had a box because it had to be done. Nobody wanted it to be like this but surely this is how it ended. I looked at Cragen as I finished cleaning her desk off. He comes over.

"Fin, I know this is hard. You can take some time off if you need."

I look at him and everyone else. I sat down at her desk. I know it's not Olivia Benson's desk anymore but to me it will always be Benson's desk. I look at her desk and take a deep breath. I can't comprehend that she will never walk into the precinct. I will never see her smile. I will never hear her laugh. I will never tell her I love her. I start to cry for the loss of my best friend. Cragen hugs me.

"Cap, I don't know how to do this. She was always there to help guide me through rough cases."

"Well what would she tell you?"

I think about it and smile. I get up with her stuff and walk out. I walk straight to my apartment. I open the door. I set her stuff on my counter and lay down on my couch. I hear my door open and I look up and see John.

"Came to check on me?"

"Yep. This is a tough one. I know you will find it hard as well."

We chatted for hours about all the good memories we had with Olivia. Times she made us laugh, times we just spent with her.

A week later we attended her funeral and it was packed. I guess she was extremely cared about and remembered.

I went home that night and decided to write a letter.

To whom this concerns,

I realize that after all this time I can't live without her. I loved her and didn't want to be in a world where cruelty takes the only true hero and selfless person I know away so I decided to go and join her in the afterlife. I am sorry and Goodbye

Fin

I called Amanda and said I can't take this pain anymore. She started talking about how this will get better but I hung up, grabbed my gun and pointed it at my head and pulled the trigger.

"Fin, You could have made it past your grief. I would have waited as long as it took."

I smile as I see Olivia the way I remembered and not the way I found her body.

"I know but it's hard to do without you"
