He kept drinking and drinking and drinking, but he only recalls the first five shots before getting in his pickup truck and driving south to Santa Ana at 1:30 a.m. to visit friends.
But at 4:45 a.m. other terrified drivers began flashing their headlights at him because for three miles he was traveling northbound at 90 mph in the southbound Interstate 5 lanes near the 17th Street exit.
He was, he recalled in legal filings, "so intoxicated" that he had no idea was he was doing.
His truck slammed into a green Toyota sedan, killing the passenger: 29-year-old Rebecca Moon. A CHP officer found Leal unconscious and a practically empty 750-millilter tequila bottle under the front seat. His blood-alcohol level registered at a whopping .29.
In September 2010, a prosecutor in the Orange County District Attorney's office won a second degree murder conviction against him, Judge James Rogan sentenced him to prison and, in early 2012, a California Court of Appeal sanctioned the conviction as legally righteous.
From inside his prison cell last June, Leal asked federal judges to overturn his case. His complaints included:
~His trial should have been moved out of Orange County because the public was especially angry with DUI offenders following the DUI-related crash that killed Anaheim Angels' pitcher Nick Adenhart.
~He couldn't have formed the necessary intent to kill for a murder conviction because he'd been driving in a alcoholic stupor that prevented him from thinking.
~CHP officers did not follow proper procedures to determine his intoxication level.
~The prosecutor, judge and media were biased against him, his defense lawyer was incompetent and his jury acted irrationally.
~Caltrans contributed to the crash because it designed a highway entrance that allowed a drunk driver to erroneously believe he was traveling in the correct lanes.
~The driver of the car with the fatality caused the crash by "veering" into his truck.
~The victim, who was gruesomely killed on impact, is to blame for her death because she wasn't wearing a seatbelt.
A federal magistrate judge reviewed the complaints and recommend dismissal of all claims after noting that Leal had ignored the teachings of two completed DUI-prevention programs where instructors emphasize that murder charges can result from fatal drunk driving crashes.
An angry Leal responded to the recommendation by arguing that he is being railroaded.
But this month, U.S. District Court Judge Michael W. Fitzgerald accepted the magistrate judge's findings and closed the appeal.
Upshot: Leal, 35, will continue to serve his 15 years to life punishment inside California second oldest penitentiary: Folsom State Prison.
