A 52-year-old female employee of a Queens maternity center who was accused of stabbing three babies and two adults on Friday morning was charged with five counts of attempted murder, while the center itself is suspected of being used for so-called "birth tourism," according to police officials. The suspect, Wang Yufen, is in police custody at New York-Presbyterian/Queens and her motive hasn't been determined as of Saturday. According to ABC News, a local assemblyman said it was likely Wang had mental health issues. The maternity center where Wang worked, Mei Xin Care Inc, which was hosting nine babies and multiple parents when the incident took place, was initially described as a day care center. They can thus finish the whole process within the six-month window of tourist visas before returning home with their newborns.
