A 26-year-old Long Island woman has been charged with manslaughter in connection with the death of a beloved Broadway vocal coach. Lauren Pazienza is accused of violently shoving 87-year-old Barbara Gustern to the ground earlier this month in the Chelsea neighborhood of Manhattan. Cops say the attack was unprovoked. Gustern died of head trauma four days later. After a wanted poster was plastered all over the city and circulated online, Pazienza, an event planner, turned herself into police.
