A high schooler came across a shocking discovery on the camera she secretly set up in her room. 

The 16-year-old decided to leave her tablet PC camera turned on in her room after continuously smelling a foul odor in her belongings. 

The 4-hour footage from March 8 shows her stepmom, Lee, walking into the empty room a total of 3 times with a needle and injecting a liquid substance into the bread and makeup. The stepmom later walks in with a spray bottle and sprays the liquid substance all over the room. 

The stepdaughter claims she has been smelling the foul odor in her mouthwash, makeup, and more for over a year. She has shared the concern with her stepmom, however, Lee simply suggested she throw away the products and told her, "You're being too sensitive."

After watching the shocking recording, the stepdaughter immediately left the house and called the police. A week later, the police conducted search and seizure of their home and found the needles and bottles seen in the recording. 

During the police questioning, the stepmom confessed she has injected bathroom cleaner, and explained she started injecting after the stepdaughter "hurt" her daughter by snatching the remote. 

The stepdaughter also claims she has been physically and verbally assaulted for 7 years. The stepdaughter said, "She told me multiple times that I don't feel like a family... I couldn't tell anyone and I just cried in my room."

Currently, the National Forensic Service is analyzing the injected substance while the police are continuing to investigate the stepmom for child abuse. The stepdaughter expressed the wish to give the stepmom the maximum punishment possible.
