An illegal alien who's been deported four times faces upgraded charges now that the elderly Air Force veteran he's accused of shoving onto subway tracks in New York City earlier this month has died.Bairon Posada-Hernandez — a Honduran national with 15 prior charges on his record — was initially charged with attempted murder in connection with the incident, the Department of Homeland Security said.'I hope he rots in hell.'However, the New York Daily News, citing court records, reported that charges against the 34-year-old suspect were upgraded to murder Wednesday after the elderly victim who had been on life support recently passed away.More from the Daily News:Richard Williams, 83, was waiting on the downtown platform for the F and Q trains at the Lexington Ave.-63rd St. station when he was shoved onto the tracks around 11:30 a.m. on March 8. Moments before, the assailant had pushed a 30-year-old man standing next to Williams onto the tracks as well without saying a word, cops said.Williams was rushed to New York-Presbyterian Hospital Weill Cornell in critical condition, the paper said, adding that his eldest daughter said he wasn't expected to survive.“It doesn’t look good,” Debbie Williams told the Daily News from her father's bedside. Richard Williams died on March 17, the paper said.Police told the Daily News that the city’s medical examiner attributed Williams’ cause of death to multiple blunt-force injuries.RELATED: 'Heinous' thug accused of shoving 83-year-old military vet onto NYC subway tracks was deported 4 times, charged 15 times: DHS "I hope he rots in hell,” Debbie Williams said of the suspect, according to the paper.Posada-Hernandez pleaded not guilty earlier this month; his arraignment on the new charges is scheduled for Monday, the paper said.The suspect's attorney Michael Papson told the Daily News his client "vehemently denies these allegations. He’s never been arrested in the state of New York — ever.”However, Homeland Security Deputy Assistant Secretary Lauren Bis had a different take, calling Posada-Hernandez a "heinous" and "serial criminal" who "should never have been able to walk our streets and harm innocent Americans."More from DHS:Posada-Hernandez first entered the country on January 2, 2008, and has been deported four different times, most recently in 2020. He entered illegally a fifth time at an unknown date and location.The suspect has a lengthy criminal history, including 15 prior charges such as simple assault, domestic violence, obstruction of police, possession of a weapon, drug possession, and aggravated assault.Like Blaze News?
