The decision of life(NCIS ff)

At the crime scene

Bishop's POV
We arrived at the crime scene. Ducky and Palmer arrived a few minutes after us. "Who do we have here?", Ducky asked. "Sergeant John Paleson. 41. He has no wife or kids. His other family lives in Canada, Calgary. Wait a second...he has a cousin here in D.C., Mia Paleson.", McGee said. "As you can see he was shot two times in the heart and once in the head. He's dead for about 12 hours. Before he died he fought. That's all I'll tell you now.", Ducky said. "OK. Thanks Duck. DiNozzo, bag and tag. McGee, photos. Bishop, help DiNozzo. I'm going to see if anyone heard gunshots." After Gibbs said that, McGee began to photograph the crime scene and Tony and I started to collect evidence. "So...are you sure that you won't come to me tonight? We can watch the movie. Or better, we can go to the cinema. New super movie is showing, San Andreas." "Tony...I won't come today. I have work at home and want to be alone a little. Maybe another day." "Okay then. If you want to be alo...well, well, well! What we have here!", Tony said opening the garbage. "The killer threw the gun here. Gibbs! We found a gun. He had a silencer.", I said. "That's the reason why neighbors didn't hear anything. Great job you two." "Thank you Gibbs!", Tony and I said in the same time. "McGee. Are you done with the pictures?" "Yes boss." "Let's get back in Navy Yard then." *Back at Navy Yard, squadroom* "Sergeant John Paleson, 41, after high school he went to the Marines, he served three tours in Iraq and one in Afghanistan, he lived alone until 2 years ago when his cousin came to live with him because she went to college.", I said. "No criminal record but in the last two weeks he transferred large sums of money to someone's bank account, more precisely $120,000. And so four times. And guess on whose bank account! Of his cousin, Mia." "Good job DiNozzo and Bishop. Find Mia and bring her here. McGee, bring evidence down to Abby." "Okay Boss.", McGee took evidence box and went to the elevator. "She is in apartment. Let's go Bishop." We took our bags and went.
McGee's POV
Once the doors of the elevator opened I went to Abby's lab. "Hey Abbs!" "Hey McGee! What do we have here?" "Evidences. Here's the killer's gun. See if he left fingerprints." Abby put gloves on her hands and I gave her the gun. "Okay. We have killer's fingerprin. All fingerprints are from same person so that must be our killer. I'll call you when I find whose fingerprint is." "Ok. See ya.", after I said that, I went.
