Berry was stabbed late Thursday night, after Miami-Dade police said the 22-year-old junior from Haines City, Fla., was involved in an argument with one or possibly more individuals outside the front doors of the school's rec center -- one of the spots where the football team trains. Several witnesses to the 9 p.m. incident were being interviewed, Miami-Dade Police Detective Javier Baez said.
FIU opened as scheduled Friday morning, with increased security for students and grief counseling available. Students living in residence halls were advised to keep doors locked, and any person at the university could be escorted around campus if desired.
Members of the FIU football team were already receiving counseling, and a football coaching clinic scheduled for Friday and Saturday has been indefinitely postponed.
"In our sorrow, we must come together," Rosenberg said in his message to the university community. "Our campus is safe. Now more than ever, you must tell this story. ... Even while we mourn Kendall and express our sympathy to his family and friends, we must not let this heinous crime overshadow the incredible track record for safety that we have."
The football team's annual spring game is scheduled for Wednesday. It's unknown if that would take place as planned.
Other than the university statement, FIU's athletic department did not have an immediate comment.
Television images showed several students, including some identified as FIU athletes, hugging and crying Thursday night near the spot where the stabbing took place, shortly before the university released official confirmation that Berry died from his injuries. One student dropped to her knees in grief just inside the doorway, screaming.
"You wouldn't expect a situation like this would happen to a guy like that," FIU student Luis Vasquez told CBS affiliate WFOR.
Berry had 164 all-purpose yards in limited use as a freshman in 2007, appearing in all 12 FIU games that season. He sat out the 2008 season with a knee injury and then had some breakout moments in 2009, rushing for three touchdowns in a span of 13 minutes against Middle Tennessee on Nov. 7 and following that up with two more scores the following week in a win over North Texas.
Berry had seven brothers and sisters, the university said. A memorial service is being scheduled, Rosenberg said.
"Last night, we lost a well-liked student who was a tireless worker in the classroom and on the ball field," Rosenberg said. "Like so many of our students, Kendall Berry had positive energy and a bright future. Last night, his grief-stricken mother described Kendall as a negotiator, not a fighter. We will not rest until the perpetrator of this crime is brought to justice."
Berry finished last season with a team-best seven touchdowns, despite not playing in the season's first seven games because of continued rehab from the knee injury.
"When you put the football in his hands, that kid can do some unbelievable things," FIU football coach Mario Cristobal said late last season of Berry.
FIU officials said they did not recall another killing on the school's campus.
