Mass shooter who opened fire at graduation party is just one of the migrants busted in LA ICE raids: 'That's who they're protesting for' | 9 June 2025 | Some of the illegal immigrants detained in the ICE raids that sparked the Los Angeles riots are convicted criminals with rap sheets for sexual assault, gang activity, and even murder -- including a Vietnamese national convicted of carrying out a mass shooting at a high school graduation party that shocked Southern California. Cuong Chanh Phan, 49, was among dozens of illegal immigrants ICE arrested in LA over the weekend in a series of raids that prompted demonstrators to flock to the streets and demand their freedom. Phan is a killer, convicted of second-degree murder. After he was kicked out of an LA county high school graduation party in 1994, he returned with gang member associates and fired semiautomatic rifles into a crowd of 30 people, killing two teens and wounding seven others, according to the Department of Homeland Security.
