Who+did+it?

If you guessed Cora and Fisher, then you are right. See after Carlos (Fisher) and Tatiana (Cora) broke in, they each killed one. Cora ended up killing Brittney and Fisher killed Josh. See Josh was cleaning the halls, so he ran through the cafeteria doors. However, he wasn't fast enough to out run the criminal, he got killed with a knife. 1) In the back... 2) In the chest... As for Brittney, she heard the gun shot so she made her way to go hide some place. She stumbled upon a pot, which dropped and caused a lot of ruckus (just enough for the two criminals to hear). Tatiana (Cora) then busted through the cafeteria's double doors and saw Brittney hiding behind the stove. She too was not fast enough, eventually she was shot in the back three times. After the two criminals made their major crime, they escorted themselves to the cash register in the cafeteria. They then took the cash in the cash register and fled, right before the police arrived on scene (Josh's twin brother heard a mysterious gun shot so he called the police)

__EPILOGUE__
 * The two criminals were caught and put in jail :D!!!!!!
