stolen 1987 Bianchi Premio

My vintage 1987 Bianchi Premio is yellow, 56 cm tall and has "Bianchi" written in large pink letters on the bottom tube and smaller letters on the seat tube. There's a sticker on the seat tube. My bike is worn some from years of riding, so the stickers might be a little scuffed. I woke up on June 10th at 5 PM after sleeping all day to find the door to my studio apartment was unlocked and my bike was gone. The door was left unlocked at around 9 AM that morning when someone left the apartment, so it was unlocked all day while I was there sleeping alone. The suspect and I both crashed at my apartment at around 4 AM that morning. She is a methhead and she brought some very sketchy methhead guy over the night before who spent 15 minutes asking me about my bike and laptops and then left my apartment. She left in the morning around 9 AM and so when I finally woke up yesterday at 5 PM, my bike was gone and my door was unlocked. The people or person that stole my bike from my apartment found the door unlocked and me there sleeping alone.
