 A Massachusetts man is expected to face a judge Monday in connection with a double stabbing Saturday inside Winchester Public Library. Ryan said more details will come out at Yao’s arraignment on Monday. Middlesex District Attorney Marian Ryan said 22-year-old Deane Kenny Stryker, of Winchester, was sitting at a table at the library on Main Street at about 10:30 a.m. when Yao allegedly stabbed her from behind multiple times with a 10-inch hunting knife. “She suffered a number of slash and stab wounds to the head and upper torso.” 
 
 The woman then left the table, apparently attempting to get to the library’s front lobby and door, according to the district attorney. In attempting to do that, the 77-year-old man sustained stab wounds as well,” Ryan said. Advertisement

 Yao, 23, of Winchester, has been charged with murder and assault with intent to murder, according to authorities. He is being held without bail, pending his arraignment Monday in Woburn District Court, Ryan said. Ryan said Yao was alone “at the time the incident began,” but said she didn’t know if any of his friends or family members had been in the library. “With respect to motive, possible knowledge of the parties of each other, that is all part of the early and ongoing investigation, which we’re conducting right now,” she said.
– The public library in Winchester, Mass., is closed until at least Tuesday, per a Facebook post, for a reason both unexpected and horrifying: On Saturday morning, a woman was fatally stabbed with a hunting knife there in what authorities are calling an unprovoked attack. Boston.com quotes Middlesex District Attorney Marian Ryan as saying Deane Kenny Stryker, 22, was in a reading room adjacent to the lobby "apparently studying or doing work" when she was attacked from behind. Jeffrey Yao allegedly slashed her head and upper torso some 20 times with a 10-inch blade, and also attacked a 77-year-old man who tried to help Stryker; that man's injuries were not life-threatening. Patrons restrained the 23-year-old Yao until police arrived. More on the crime: The court appearance: Yao was arraigned Monday in Woburn District Court on one count of armed assault with intent to murder and one count of murder, reports NECN. A not guilty plea was entered, and he was held without bail. His next court date is April 11.
