The victim said he waited four hours—until 7:15 a.m.—as a security guard, locksmith, and engineer worked to open his door.

The same lock was jammed a total of five times that week, the victim said, and he remembered that Wan offered to help him remove the plastic from the lock on several occasions.

On April 21, the victim said he fell asleep in the Greenough common room, and awoke to find one of his flip-flops missing. An HUPD officer later found it on top of a vending machine in the Greenough basement.

A similar event occurred on April 24 when the victim woke up on the Greenough common room to find one of his sneakers missing.

The victim said the proctor found the sneaker in the bathroom, covered with paper towels, several days later.

Another time, the victim borrowed Wan’s Social Analysis 10 sourcebook. When Wan asked for it back, the victim could not locate the sourcebook.

Wan them told him that he needed the sourcebook, so if the victim could not find it, he could buy one from Wang for $55, who happened to own an extra sourcebook.

The victim said he later found out that Wang was not even enrolled in Social Analysis 10.
