Camay De Silva was visiting campus when she was shot around 1:40 a.m. on April 21.
During a news conference on Monday morning, Dover police announced the arrests of Destry Jones, 20, and Damien Hinson, 18, both of Dover.
Jones and Hinson were charged with murder in De Silva's death.
They are also charged with the attempted murder of a 20-year-old man and a 21-year-old man during a fight that happened before shots were fired.
Jones was taken into custody by U.S. Marshals in Brooklyn, New York on May 2. Hinson was taken into custody in Dover.
Neither suspect has any connection to Delaware State University, police said.

At the time of the shooting, police say Dover officers heard what they believed to be shots fired along College Road.
At about the same time, Delaware State University police received reports of shots fired following a fight in the area of the Tubman-Laws dorm.
Meanwhile, a separate call was made to report a woman on the ground near the Warren-Franklin dorm, which is next to the Tubman-Laws dorm.
That woman, now known to be De Silva, had been shot in the head. She was rushed to the hospital but ultimately died.
She was not involved in the fight and was not the intended target, police said.

Camay's mother, Shanelle De Silva, was there as the arrests were announced.
"They took someone who had nothing to do with what was going on with them. And their senseless choices affected a whole lot of people," she said.
She also had a message for the suspects.
"I hope you can live with what you did, and that guilt eats you up," she said.
De Silva graduated high school with honors in 2023 and began college at Morgan State University before a mass shooting there last October pushed her closer to home, her family said in an interview with Action News late last month.
De Silva was a computer science major at Delaware Technical Community College, and her mother says she was in the process of transferring to Delaware State.
