Yesterday, in Times Square in New York, a 26-year-old man named Richard Rojas plowed into a crowd of people with his car killing one 18-year-old girl and injuring 22 others. Family and friends say that Rojas had been slipping deeper and deeper into his mental illness and had severe paranoia. He was in the Navy for four years, and when he returned is when his family says he had become a different person. Rojas also had a problem with alcohol and drugs. He has given several reasons for his actions but police say they have no definite motive or reason why he chose to do what he did. The 18-year-old girl that was killed was Alyssa Elsman. Rojas has been charged with murder, attempted murder, and aggravated vehicular homicide.
