The defendant argues that his bedroom was a container within the meaning of G. L. c. 140, § 131L, and that he was not in violation of the statute because the bedroom door was locked. The defendant's interpretation of the statute ignores the requirement that a container must not only be "locked" but also "secure."
...The use of the word "secured" in G. L. c. 140, § 131L, comports with its use in G. L. c. 140, § 123, and indicates that the container must not merely be locked, but securely locked.
