Your boss has been suspended, someone reported her?

for leaving cooked chicken in the oven overnight and was going to serve it to children the following day. There is just her, you and another member of staff working in the kitchen yet it has been said that a person who works within a different department was the one who reported her. You also have another job, your boss from that job comes to you to tell you there has been a phone call and allegations have been made about you. Would you (as i have) immediately suspect the boss who has been suspended. Would you think they suspect you for reporting them and so they are (in their mind) getting their own back.
