“We expected his parents to be like, ‘Come home now or we’re going to kick your ass,’” Wang said.

Instead, Lin’s parents came up the next weekend and gave him money to look for an apartment of his own.

Wang said Lin then spent the next two weeks claiming to be looking for a job and a place to live, but spent most of his time at Adams House.

“He wasn’t supposed to stay for two and a half weeks. He was supposed to leave after two or three days, which he didn’t. I didn’t feel comfortable kicking him out,” Wang said. “He kept on saying, ‘Oh yeah, my parents are coming this weekend.’ Then, ‘Oh yeah, I’ll get an apartment soon.’ Then, ‘Oh yeah, apartment [rentals] don’t start until the first of the month.’ He just kept on pushing it, week by week.”

Wang said Lin was able to enter Adams House by piggybacking off people with keycard access.

Chang said Lin was finally found out on July 27 when she, Lin and several friends gathered in a friend’s room. She said proctors meeting in a room diagonally across the Adams House courtyard saw the gathering and came to investigate the unregistered event. In the Summer School Program, a party is defined as 10 or more people in one suite.

When the guests were asked to produce Harvard identification, Lin was unable to do so.

Catalano said HUPD was called that night by the Summer School Program dean’s office.

HUPD issued a trespass warning—an official notification that an individual is no longer welcome on a property and can be arrested if he or she returns to that property—and then escorted Lin to the South Station bus terminal, Catalano said.Catalano added that Lin cooperated with the police.

“It does not appear that this individual posed any danger to the residents of Adams House,” Catalano said.

But Catalano said such a stay could be a cause for concern.

“Anytime there is an unauthorized or uninvited person, that concerns the HUPD,” Catalano said.

Chang and Wang both confirmed that they were brought before the Administrative Board for harboring Lin—an indication that their case could have resulted in their expulsions, particularly given the students’ perception that most students brought before the body have been expelled this summer.

Both said they expected to be expelled from the program. Ultimately, the two were allowed to stay.

“I was very surprised,” Chang said.

But despite a punishment more lenient than expected, Wang said the incident could change his college application plans.

“I was thinking of applying here, but I’m pretty sure I’ll get tagged now, so it’s a tougher decision,” Wang said.
