My HP Envy dark grey laptop got stolen!!!!

I came back from class with a banging headache and one of my roommates offered to go buy me some painkillers… Took them after eating and decided to try to study and placed laptop out of my school bag onto the bed. Later couldn’t keep my eyes open and didn’t realize what time i had slept but i knew before sleeping the door was locked. I woke to discover my laptop missing from the bed and my other roommates fast asleep. i alerted everyone of the theft and they immediately rummaged through their things to see if anything of theirs was missing. The one who bought me the painkillers complained of her missing phone aside that and my laptop, nothing else was stolen. Later after reporting at the porters office, i discovered that my second roommate came in late from the study room with her boyfriend and female third party and was let in by the third roommate while the fourth was already fast asleep.
