Rodolfo Pichardo, 21, of the 400 block of Hinman Street, was released yesterday, the same day he turned himself in to authorities. At this time, the incident appears to be accidental in nature.

The accident occurred at around 4:45 p.m., at the same Hinman Street home where Rodolfo and the 15 month old, Jared Pichardo, reside. Immediately after backing over Jared in a 2002 Ford Explorer, Rodolfo stopped for a short amount of time and a second uncle, Rodrigo Pichardo, 24, also of the Hinman Street address, entered the vehicle. Both he and Rodolfo then fled the scene. Jared Pichardo was pronounced dead at 5:25 p.m. Saturday, at Rush Copley Medical Center where he was taken by paramedics.

Investigators say that Rodolfo apparently stayed in the Aurora area. A family member of the Pichardo’s convinced Rodolfo to turn himself in to police which he did yesterday afternoon. Rodrigo Pichardo’s whereabouts are not known.

Investigators say that Rodolfo Pichardo was cooperative during the investigation. He apparently fled because he panicked and is obviously distraught over the loss of his nephew.

Aurora Police will complete interviews with other witnesses before presenting the case to the Kane County State’s Attorney.
