The Linn County Medical Examiner has identified the body of the man pulled from the Cedar River Tuesday as 28-year-old Silverio Matais-Perez of southeast Cedar Rapids. The medical examiner is waiting on toxicology reports to determine the cause of death.

Several witnesses reported that Perez went underwater and failed to re-emerge while trying to cross the Cedar River on Saturday evening around 7:00 p.m. Firefighters searched the Cedar River for four days before finding the body Tuesday just before noon.
