Now I am a Detective

Lesson was going well, students seemed to be engaged, lets just end with a brief explanation in the Lab. I gave instructions to move into the lab, which is just thru a door, and has large windows to see into the classroom. Two students lagged behind just for a minute to finish the last question on the worksheet. My wandering student had to be corralled back into the lab twice. Ten minutes later we finished the demonstration and headed back to the classroom. Only 5 minutes left in the block. Then it happened. A student went into her purse that she had left in the classroom, only to find her cell phone & wallet missing. (Of course she is one of my brightest, and was just homecoming queen the past weekend) The door to the classroom that I always keep closed and locked had not been completely closed by a student who had left class 15 minutes prior for a trip to the nurse to take meds. We did not see anyone come into the classroom. So now I have to call an administrator. He comes running in, the principal shows up with the campus officer. Bell has rung, but no one is allowed to leave. Next class is coming in. I'm getting a lesson on search & seizure! Next I'm calling the nurse to check on the student who left for the meds and the nurse says she has never heard of her. She has been leaving class 15 minutes early for the last 5 days to "take meds". At the end of the day, having filed the proper paperwork, written a admin referral for skipping, called a mom to tell her, her daughter has lied, my stomach was in knots. The biggest reason was that someone who I see everyday has made the class feel unsafe in my room. There is one amusing note. I had made arrangements to film the next day's class for NTI a week ago. Now the camera was set up & they all thought it was because of the theft. I never said anything to the contrary.
