An Emerson student who was struck in the head during a confrontation with a group of young men while leaving a party Saturday “will not be able to sustain life” after suffering severe brain damage, according to his family.

The victim, sophomore Daniel Hollis, was leaving a party with his friends when another group of college-aged boys confronted them and a fight ensued, his family wrote on a website dedicated to sharing medical updates with other family, friends and community members.

Hollis was taken to a Boston hospital and diagnosed with a blood clot on his brain, his family wrote, adding that they believe he fell and hit his head on the pavement.

Despite the success of his initial surgery, in an update posted Monday family members wrote that Hollis’s most recent scans showed irreparable damage to his brain stem and that he will not regain consciousness.

“There is damage to areas of the brain that control body functions such as breathing and his heart. He will not be able to sustain life, even with the aid of life support systems,” his family wrote.

Boston Police confirmed that they responded to an assault and battery at Parkvale Avenue in Allston at 1:30 a.m. Saturday and that the victim was rushed to a local hospital with life-threatening injuries.

No arrests have been made in connection to the incident, police said.

“The Emerson College community’s thoughts and support are with Dan’s friends and loved ones during this difficult time,” said Michelle Gaseau, Emerson’s director of communications and media relations.

Hollis, a sophomore marketing and communications major at Emerson, graduated from Hopedale High School and played for the school’s lacrosse team. He’s also a member of the Emerson men’s lacrosse team.

“Please continue to keep Dan in your thoughts and prayers. We ask that you focus on the positive: his infectious smile, his goofy sense of humor, his love for music, hockey, lacrosse and most importantly his love for his friends and family,” his family wrote.

“The positive energy is making it to him and surrounding him with love while he is still with us.”
