Keitt, who is reportedly homeless, is charged with assaulting and robbing Yvonne Sherwell-Demakopoulos, 85, in the elevator of her W. 13th St. building on Sat., Dec. 8. His image was captured on surveillance camera video, and he was arrested three days later after being spotted by Stuyvesant Town security. Keitt is also being charged with victimizing three other women in elevator robberies, including a 58-year-old woman in Far Rockaway, Queens, on Dec. 4; a 28-year-old woman in the East Village on Dec. 8; and a 22-year-old woman near Gramercy Park on Dec. 9, when police say he used a gun. The robber not only stole Sherwell-Demakopoulos’s handbag but also her wedding ring. According to WABC News, the West Village woman is now carrying a new warning device for safety — a whistle.
