 A Massachusetts man is expected to face a judge Monday in connection with a double stabbing Saturday inside Winchester Public Library. 
 
 Jeffrey Yao, 23, of Winchester, is due in Woburn District Court to face one count of armed assault with intent to murder and one count of murder. 
 
 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. 
 
 Ryan said Stryker suffered several slash and stab wounds to her head and upper torso. She was taken to an area hospital where she was pronounced dead. 
 
 Winchester Stabbing Victim Identified 
 
 A family spokesperson tells NBC10 Boston that the woman killed in a stabbing at the Winchester library is 22-year-old Deane Kenny Stryker. (Published Sunday, Feb. 25, 2018) 
 
 Authorities said several people at the library tried to intervene, including a 77-year-old man who was stabbed in the arm. Ryan said that man is expected to survive. 
 
 Stryker was a first-year student at the University of New England College of Osteopathic Medicine. 
 
 UNE President James Herbert released a statement on Sunday, saying in part, "The University of New England community was shocked and saddened to learn of the death of one of our students, Deane 'Kenny' Stryker, who was killed on Saturday. We send our deepest condolences to Deane’s family and friends, who are facing an unthinkable tragedy." 
 
 Family friend Brad Harrington said Stryker was a "special kid." 
 
 "She decided early on that she wanted to be a doctor," Harrington said. "She’s overcome some, you know, real obstacles in her life." 
 
 NBC10 Boston learned from sources Sunday night that Stryker is the daughter of Dr. Timothy Stryker, who was questioned in the 1993 death of his girlfriend. 
 
 Neighbor Peter Luongo says Yao lived with his parents nearby for years but that he started behaving erratically last summer. 
 
 Neighbor Nicole Luongo said Yao had allegedly attempted to break into area homes and cause damage to property. 
 
 "I would sleep with a bat under my bed," said Nicole Luongo, who had gone to the police with concerns. 
 
 Authorities are investigating the possible motive for the stabbing. 
 
 Friends said Stryker and Yao both attended Winchester High School but it's unclear whether they knew one another. 
 
 Yao is being held without bail pending his arraignment. It’s unclear if he has an attorney. ||||| A 22-year-old woman is dead following a double stabbing at Winchester Public Library on Saturday morning, authorities said. 
 
 The second victim, a 77-year-old man, sustained nonlife-threatening injuries while attempting to intervene, and the suspect, 23-year-old Jeffrey Yao, of Winchester, was arrested at the scene and has been charged with murder, Middlesex District Attorney Marian Ryan said at a press conference Saturday afternoon. 
 
 Ryan said more details will come out at Yao’s arraignment on Monday. Here’s what we know as of Saturday afternoon: 
 
 The incident 
 
 Winchester police received “several” 911 calls at about 10:38 a.m. Saturday reporting a stabbing at the library, according to Ryan. With the police station located nearby, officers “almost immediately” responded to the scene, where they discovered two people suffering from stab wounds, she said.

 The 22-year-old woman had been seated at a table in a reading room off the library’s main lobby “apparently studying or doing work,” according to Ryan, when Yao allegedly approached her from behind. 
 
 “Mr. Yao began striking her with what we now know to be a — what appears to be a — hunting knife with approximately a 10-inch blade,” Ryan said. “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. 
 
 “A number of patrons came to her aid. In attempting to do that, the 77-year-old man sustained stab wounds as well,” Ryan said. 
 
 Ryan said library staff responded, too. The 77-year-old man had been seated in “close proximity” to the woman, along with one other patron, she said. 
 
 The patrons were able to corral Yao until police arrived and subsequently took him into custody, she said. 
 
 At the press conference, Winchester Police Chief Peter MacDonnell thanked the people who came to the woman’s aid, as well as his officers. 
 
 “I would like to thank all those people for their help during this incident, and I’d like to thank my officers, as well, for their quick response to this incident,” he said.

 Both victims were taken to area hospitals, where the woman died as a result of her injuries, authorities said. 
 
 The victims 
 
 Authorities have only identified the woman as a 22-year-old from Winchester. 
 
 “Identification will not be released at this point, pending the notification of the next of kin,” Ryan said Saturday afternoon. 
 
 While attempting to intervene, the 77-year-old man, also from Winchester, was stabbed in the arm, according to authorities. Ryan described his injuries as “nonlife-threatening.” The man, who authorities have not publicly identified, remained hospitalized Saturday afternoon.

 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. 
 
 Ryan reiterated that point when asked by a reporter if the woman was targeted. She said Yao was “known to police” but wouldn’t say how. 
 
 “We’ll have more information about that at his arraignment on Monday,” 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.
