A US Navy veteran who plowed a car into pedestrians in New York's Times Square, killing a woman and injuring 22 other people, has been charged with murder and attempted murder, police said Friday.
Thursday's incident sparked fear in the US financial capital after deadly car-rammings in London, Berlin and the French city of Nice, but authorities said there was no evidence the crash was terror-related.
Richard Rojas, 26, a former Navy electrician from the Bronx, was arrested at the scene and later charged with one count of murder in the death of an 18-year-old tourist and with 20 counts of attempted murder.
Police confirmed the identity of the young woman who was killed on the spot -- Alyssa Elsman, 18, a tourist from Portage, Michigan. Her 13-year-old sister, Ava, was among the injured, four of whom were in critical condition.
Shortly before noon Thursday, Rojas's Honda Accord suddenly hurtled onto a Seventh Avenue sidewalk in Times Square -- one of the world's busiest districts -- and continued on for three blocks, bowling over pedestrians and sending others fleeing in fright, police said.
The car came to a halt after colliding with a metal pole.
Rojas was arrested for drunk driving in 2008 and 2015, and detained earlier this month on charges of menacing behavior, police said. He was submitted for drugs and alcohol tests after his arrest Thursday.
Test results were not yet available but Mayor Bill de Blasio was quoted by the New York Post as saying that "we know there was some kind of drugs in his system."
News reports Friday drew a portrait of a troubled young man who seemed changed when he returned home in 2014 from a three-year stint in the US Navy.
A friend, Hansel Guerrero, told the New York Times that Rojas began expressing conspiratorial thoughts about the government, that he was often physically threatening, and was a frequent consumer of alcohol and cannabis.
During his arrest Thursday, Rojas allegedly told police: "You were supposed to shoot me! I wanted to kill them," New York newspapers reported. He also said that he "hears voices."
Several friends said they had encouraged him to seek psychological counseling, but he did not do so.
Authorities said they were studying ways to reinforce security around Times Square, one of the city's top tourist destinations. Police patrols there have already been beefed up in recent years, particularly after a 2010 car bombing attempt.
Protective bollards -- short, sturdy posts to prevent vehicles from driving onto sidewalks -- were installed late last year, just in time for the New Year's Eve celebration that regularly brings a million or more people to Times Square to watch the famous Waterford crystal ball drop at the stroke of midnight.
USA Today reported that the bollards had helped slow, and finally stop, Rojas's car.
