Police in Virginia have released two images of people they say attended the April 23 house party in Herndon, Virginia, where 21-year-old George Mason University student Hosung Lee was allegedly beaten and stabbed to death.

Authorities said those pictured could have information critical to their ongoing investigation into Lee’s death.

A statement from police says Lee, who also went by “Steven,” was stabbed before being beaten by a large group of revelers. Following the assault, the late student’s friends allegedly drove him home and placed him in his bed, the statement says.

Family members found Lee’s lifeless body several hours later and called the Fairfax County Police Department, the statement says. Last week, the state’s medical examiner ruled Lee’s death a homicide, revealing the student died from being stabbed in the chest.

Investigators learned from several witnesses that Lee was involved in a physical altercation during last month’s party that, at times, involved as many as 20 people. It is unclear what prompted the fight.

The police statement says detectives spent three days inside the home where the party was held, collecting more than 700 pieces of evidence.

Attempts to reach Lee’s relatives were unsuccessful Monday. His friends also refused to talk to PEOPLE about his death.

A GoFundMe account has been set up that claims it is raising money for Lee’s family. It has already raised over $6,300 towards its $10,000 goal.

“For those of you who knew Steven Lee you know he was someone that had the kindest heart and was a blessing to those around him,” the GoFundMe page reads. “He was also someone who was always willing to help anyone in need.”

Fairfax County police ask anyone who might know the identity of those pictured to contact police at (703) 246-4057 or (866) 411-8477.
