The rally was in honor of 18-year-old Mario Aguilar.
He came to the United States when he was 16 to escape death threats from an organized criminal gang in Guatemala and was attending Wilbur Cross High School.
Aguilar was in a car crash back in August and was charged with driving under the influence.
When he went to the Milford courthouse on Sep. 10, ICE officials grabbed him and detained him. He has not been given a bail hearing.
Fellow classmates and state officials, like Senator Richard Blumenthal and Mayor Toni Harp, came out in support.
“The facts here, on the merits, on the law, totally justify our position,” said Blumenthal. “We’re gonna go to ICE. We’re going to be pounding on their door. We’re gonna be going to court; we’ll be pounding on those doors too.”
While he came into the country illegally, supporters said he did it to live the “American dream.”
“He was working 30 hours a week, sending money back home to his mom and family, and really he just wants what we all want is that American dream — a better life,” said Wilbur Cross High School Principal, Edith Johnson.
Several school staffers drove to Boston to be with Aguilar during his hearings.
“The assistant principal, social workers and counselors a group of them went to Boston and sat in the bond hearing,” Johnson said. “We provided over 400 letters that students wrote”
Johnson said Aguilar has continued to keep up with his studies and homework so he can hopefully graduate.
