Renna was the first fatality in the IRL since Scott Brayton was killed during practice for the 1996 Indianapolis 500, and the first in American open-wheel racing since Greg Moore died in a major accident during a CART race at California Speedway in 1999. An autopsy was conducted by Marion County Coroner John McGoff, who determined Renna died instantaneously after sustaining fatal, blunt-force head and chest injuries from the high force of the impact. On the afternoon of October 27, Renna was given a memorial service at St. John the Evangelist Catholic Church; another took place four days later at St. Peter's Catholic Church in Deland, Florida, and was attended by 400 people. Darren Manning took Renna's seat at CGR.
