“I knew the victim because our paths used to cross and we used to say hello,” said former UM student Kyle Swan, who lives at the same building where the victim lived at the Santona Condo and rental complex right across U.S. One from the University of Miami.

Swan told CBS4’s Peter D’Oench, “It’s shocking to find out that it was someone who was own age and somebody did that to him. We live here and we don’t know if there was a chance that someone who knew him did or if it was a stranger. We would like to know who did it and find out quickly so police can resolve this case soon rather than later.”

Miami-Dade Police say his body was discovered inside apartment number 20 on the 2nd floor by his roommate at 3:44 on Sunday afternoon. They said it was a gruesome bloody scene with multiple signs of blunt trauma on the victim.
