Fairfax County Police are issuing appeal to identify those who were at party

A college student, 21, was beaten by a mob and stabbed at a party before friends drove him home and placed him in bed, where he was discovered dead the next morning, according to a search warrant.

Hosung 'Steven' Lee, a student at George Mason University, died from a stab wound to the chest, with the state medical examiner ruling it a homicide last week, according to the Washington Post.

Lee attended a party in Herndon, Virginia, the night before, where a witness said a mob of 10 to 15 people beat him while he lay on the kitchen floor, according to search warrants filed by Fairfax County police.

Hosung Lee, also known as Steven, (pictured) was beaten and stabbed at a party in Herndon, Virginia on April 23, with a witness telling detectives a group of 10 to 15 people 'stomped, kicked and punched' him as he lay motionless on the kitchen floor

A witness told detectives Lee was stomped, kicked and punched by a large group at the party, which extended into the next morning according to court documents cited by the Post.

Police had appeared at the home on the 12600 block of Oxon Road earlier that night due to a noise complaint, WTOP reported.

It is unclear what prompted the attack on Lee and why his friends did not seek medical help.

Instead, they drove him about five miles to Centreville, where Lee lived with his sister and parents.

According to the search warrants, his friends placed him in bed, and Lee was found dead by a family member around 4.24pm on April 24, according to WTOP.

Lee, 21, was found dead in his home on the 5600 block of Gresham Lane (pictured), about five miles away from the party on Oxon Road

The witness identified one person who allegedly participated in beating Lee, but he refused to cooperate with authorities when they tried to interview him. He has not been charged.

Police obtained a search warrant for his home as well as the house where the party took place.

More than 700 pieces of evidence were collected, including cigarette butts, shot glasses and beer cans, according to WTOP and the Post.

Police are looking into the possibility of gang activity, although one officer said that is a particularly difficult task given their evolving nature.

But the assistant pastor at New Covenant Fellowship Church where Lee's family attended while he was in high school told WJLA: 'I couldn't believe it, it was surreal.

'He was a typical kid who loved his friends and loved coming to church.'

A GoFundMe page, which has raised more than $6,000 for his funeral expenses, described Lee 'someone that had the kindest heart and was a blessing to those around him'.

An investigation is ongoing, with Fairfax police issuing an appeal to identify people who attended the party. So far no one has been arrested in connection to Lee's death.
