Court documents say Cavallo told investigators he was driving 30 mph at the time of the crash and admitted to drinking alcoholic beverages and blood test revealed his his blood alcohol content was 0.13. An accident report said after the initial crash, a second vehicle hit Espinel while she was lying in the street. The driver of the second vehicle, who has not been charged, told investigators she didn’t see Espinel lying in the street until moments before she hit the student, the Tribune reported. Cavallo, who awaited officers at the scene, was never arrested and appeared in court by way of a misdemeanor summons. Tim Spencer, commander of the St. Joseph County Fatal Crash Team (FACT), told the Tribune that Cavallo was not charged with anything pertaining to the crash itself because there was no proof that he actually caused the crash. The South Bend intersection where Notre Dame students Rojas and Espinel were killed Rojas' childhood friend created an online petition 'called Justice for Olivia Rojas and Valeria Espinel: Arrest Justin Cavallo' that has garnered over 20,000 signatures 'We need to prove that the driver actually caused the crash,' Spencer said. 'Ultimately those charges were not filed. Cavallo was just charged with simply operating while intoxicated, nothing pertaining to the crash itself.' Rojas' childhood friend Natalie Hodnett created an online petition called 'Justice for Olivia Rojas and Valeria Espinel: Arrest Justin Cavallo' that has garnered over 20,000 signatures. The petition is advocating that Cavallo be charged in the connection to the accident. 'Cavallo was only charged with two misdemeanors: operating a vehicle with an alcohol concentration above 0.08 and operating a vehicle while intoxicated,' the petition said. 'He was not charged with anything pertaining to the crash itself because according to Tim Spencer, commander of the St. Joseph County Fatal Crash Team, there is no proof that Cavallo actually caused the crash.' 'The facts are that Justin Cavallo made the decision to drive under the influence and two nineteen year old girls were run over and killed,' the petition added. 'We demand that he gets charged appropriately.' Hodnett told the Tribune she created the petition in the hopes of deterring potential drunken drivers while advocating for more serious consequences for Cavallo. 'If they have heard of this story and see that somebody could kill two people and only get away with two misdemeanors, not even pertaining to death, they might not think that it's such a big deal, and I really want to prevent this from happening again,' Hodnett said.
