Detectives are on their fourth day of investigating the case of a University of Miami student found dead Sunday inside his Coral Gables apartment.
Authorities are looking for a man they said they want to question, but they still haven't announced any suspects.
On Wednesday, cleaning crews moved what appeared to be a mattress wrapped in plastic out of the apartment on Santona Street.
In the days prior, 23-year-old Yasser Abualfaraj was found dead by his roommate in that apartment. Police said his body had multiple signs of trauma.
The crew also removed three red biohazard bags as neighbors continue to try and wrap their heads around the tragedy.
Just a day after Abulfaraj was found dead, detectives were knocking on doors and dusting for fingerprints at other apartments. On Tuesday, they released a sketch of a man they said was seen in the area shortly before Abulfaraj's body was found.
The man in the sketch isn’t being called a suspect at this point, but is wanted for questioning.
Detectives were back at the complex Wednesday, following up with neighbors.
Anyone with information about the case is asked to call Miami-Dade Crime Stoppers at 305-471-8477.
