Marco Beltran and his colleagues were riding their bikes to Walmart on June 4 when the group was struck by 50-year-old Gerilyn Weberlein.
According to police, Weberlein showed signs of intoxication at the scene. She has been booked into jail.
Beltran was in the U.S. on a visa program with several others to work for the summer and learn the culture.
His family came from Colombia to say their goodbyes. Beltran's sister, Paola, wanted to share an important message.
"I would like to thank all of the Galveston community for all the support, for the love that they are sharing to us," she said.
A memorial service will be held Saturday morning at Sacred Heart Catholic Church.
