SIOUX FALLS, S.D. (KELO AM) - Sioux Falls Police released the name of the two year old boy who died last week as Tyrese Robert Ruffin.
27 year old Joseph Robert Patterson is charged with aggravated assault and aggravated battery in the boy’s death.
Officer Sam Clemens says an autopsy is being performed. He says in the past it takes anywhere from two to four weeks for autopsy results to come back. Authorities many have an initial assessment in the boy's death but it won't be official until all the teats are done.
Lincoln County State’s Attorney Tom Wollman says once all reports are in he may convene a grand jury to consider more serious charges against Patterson.
Ruffin is the son of MInnesota Vikings running back Adrian Peterson.
