Investigators suspect that on Aug. 25, Hernandez lost control of a Jeep Grand Cherokee, hit a car and then 22-year-old Ashlee Zimmer while she was having a smoke on the sidewalk near 844 N. 100 West. Her body was dragged beneath the SUV as it crashed through a fence and hit a building.
Zimmer was taken to the hospital, where she later died.
Hernandez fled on foot but was found later hiding behind a nearby dumpster, according to the charges.
Once in custody, Hernandez admitted to drinking five to six beers earlier at a wedding, then another five to six beers at home before driving the SUV, according to the charges. He submitted to an intoxilyzer test that showed a breath alcohol content of 0.169 more than twice the legal limit of 0.08, the charges add.
He also consented to a blood draw. Investigators are still waiting on the results of that test.
Hernandez also told investigators that he was on his way to a friend's house when bright, oncoming headlights caused him to lose control of the vehicle, according to a probable cause statement. He also told police that after the crash he fled out of fear of a man who was yelling at him and also to find help; he then saw the police officers and hid, also out of fear, the affidavit adds.
When police asked him about Zimmer, Hernandez told the officers that he not know he had hit and killed someone, according to the affidavit.
"[When a sergeant asked Hernandez] now that he knows he had hit and killed a person with the vehicle he was driving, how did that make him feel?" the affidavit says. "[Hernandez] advised he felt sad."
A judge set a $500,000 cash-only bail for Hernandez during a Monday morning court appearance. He has a prior DUI conviction from 2008.
