The death of Mr. Souza, an engineering student who graduated from Blind Brook High School in Rye Brook, N.Y., last year, came just five weeks after another Binghamton student was killed. Haley Anderson, a 22-year-old nursing student, was found dead in an off-campus residence on March 9 after being strangled.
Though the proximity of the killings rattled students at Binghamton, part of the State University of New York system, there was no indication that they were related. A different suspect was identified in the first case: Orlando Tercero, a fellow nursing student whom the police said Ms. Anderson had briefly dated. The Press & Sun-Bulletin, a newspaper in Binghamton, reported last month that Mr. Tercero had been accused of slashing Ms. Anderson’s tires in September.
Mr. Tercero fled to Nicaragua, where he has dual citizenship, before Ms. Anderson’s body was found, and American officials are seeking his extradition.
Harvey G. Stenger, the university president, told reporters that the two killings in such proximity were “definitely the hardest thing that I’ve been through since I’ve been here,” adding, “You can understand how difficult it must be for parents and for friends.”
In a statement on Monday, Dr. Stenger sought to reassure students and their parents.
“Unfortunately, we live in a time where violence is part of society, and, as a campus of 17,000+ students and several thousand faculty and staff, there are occasions where violence will intrude on our campus,” he wrote. “We will continue to focus on keeping ours a safe campus, with a fully empowered state law enforcement agency that works closely with the residential communities to protect life and property.”
