2 3 and 5 might have been working together, 2 would shut down the security cameras, 5 Would act suspicous nervous beacause she didnt want 3 to be suspicous,and 3 stole the ring
Suspect #2 the hint was cameras not working and suspect 2 had all access to security there nothing to look at if the cams aren't working and suspect 2 is trusted so no one would have suspected them thats my reasons 😋
