MELROSE, Bronx (WPVI) -- A mother has been charged, accused of shoving her toddler strapped in a stroller down subway stairs in New York City on Thursday. According to WABC-TV , Jessica Mixon, 25, faces charges of reckless assault on a child, reckless endangerment and abandonment.Around 2:30 p.m. at the 149th Street and Grand Concourse Station in the Melrose section of the Bronx, police said a 2-year-old boy was strapped into a stroller, then shoved down an entire flight of cement stairs by his mother.Witness John Smith said it was horrifying."He was all busted up by the time they brought him up," Smith said. "Baby was screaming, busted his eye, his nose was bleeding, blood was coming out of his mouth, his head was bleeding."Mixon lives in a city-run homeless shelter in Morris Heights."She was just cursing, you know, you know, '(expletive) this' and 'I can't do it,' things like that,'" Smith said.Mixon, of the Bronx, was taken to Bronx Lebanon Hospital for a psychological evaluation."She just stood right there against the wall and just stayed there, that's it. She kept on saying, 'I don't care about the baby. I don't want him,'" Smith said. "For a mother to do that, she must have been under a hell of a lot of pressure or something, for a mother to do that to a baby, I don't know."The 2-year-old boy was taken to Lincoln Hospital in serious but stable condition. He suffered a cut to his left eye and an abrasion to his head.----------
