 (CNN) The woman accused of driving under the influence and plowing her car into a crowd of spectators at an Oklahoma State University homecoming parade also faces murder charges, police said Sunday. Adacia Chambers, 25, is charged in connection with plowing her car into a crowd of people watching the end of the OSU homecoming parade Saturday morning. He admits he is not a psychiatrist or psychologist, but he has experience and understands the warning signs of mental illness. Her boyfriend, Jesse Gaylord, told him that she suffers from diabetes, but is not being treated or medicated for the condition, Coleman said. Chambers' mother also reportedly suffers from bipolar disorder and has been hospitalized in the past due to her illness, Coleman said. Coleman said he's met with people who saw Chambers the night before, the morning of and just before the incident. She worked at a fast-food restaurant and left for work early so she could arrive for her 9:00 A.M. shift on time Saturday morning. A witness said she appeared to be crying, but was not unsteady on her feet as she walked down a street away from the restaurant, according to the Stillwater NewsPress. What happened over the course of the next hour leading up to the crash is unknown even to Chambers, Coleman said. When he met with his client Saturday night, Coleman said Chambers gave "inappropriate" answers to some questions and lacked emotion at moments it would be expected. What happened 
 
 At 10:31 a.m., a 2014 Hyundai Elantra traveling southbound on North Main Street at a high rate of speed crashed into an unmanned police motorcycle and continued into a crowd near the end of the parade route at North Main and Hall of Fame Avenue, just a few blocks east of the university's football stadium. Dead are retired OSU professor Marvin Lyle Stone, 65; Stone's wife, Bonnie Lynn Stone, also 65 and a longtime OSU employee; Nikita Nakal, 23, a University of Central Oklahoma graduate student from Mumbai, India; and 2-year-old Nash Lucas, the son of an OSU sophomore chemistry major who also works for the university's Parking and Transit Services. It also injured dozens of people, including 11 victims younger than 13. McNitt said he felt a gush of wind, then heard a boom, followed by screams. One minute, McNitt was standing beside his stepfather, 54-year-old Leo Schmitz, near the end of the parade route. McNitt described his injuries as severe, but he praised doctors for their care and people from across the state for coming together during the tragedy. Of the 47 people treated after the crash, 17 remained hospitalized and four were in critical condition Sunday, officials said. "We missed the game," he said, "but we feel the love, and we'll get through this." Any opportunity to see a Cowboy football game, he's there.” 
 
 Never could McNitt have imagined what happened instead. "All there was was smoke and panic. "It's been a crazy 24 hours," Mark McNitt said, tearing up as he told reporters about the crash and its aftermath. Band members didn't see the crash, he said, but a band member's mother was injured in the crash, Tanner said. Among them was an F4 tornado that devastated the community in 1991. "Our students come to Central with their unique goals, hopes and dreams, and Nikita was undoubtedly no different." "While our thoughts and prayers are with the Oklahoma State University community tonight following the tragic events during OSU's homecoming parade this morning, it is with deep sadness that I ask you to extend those sentiments to the family and friends of one of our own students," wrote President Don Betz.
– The woman accused of driving into an Oklahoma State University homecoming parade is clearly mentally ill and has no memory of the crash that killed four people and injured dozens more, her lawyer says. "I have deep concerns about her competency at this point," attorney Tony Coleman tells the Oklahoman. "I'm not a psychologist or psychiatrist, but I can tell you she's suffering from mental illness." Coleman says he believes 25-year-old Adacia Chambers suffered some kind of blackout because of her illness and has no memory of the crash or of the hour leading up to it, during which she left her job at a fast-food restaurant soon after arriving. Three adults and a 2-year-old boy were killed in the crash, and four of the 47 people injured are in critical condition, CNN reports. Chambers has been charged with four counts of second-degree murder. She also faces a DUI charge, but Coleman says nobody saw her drink or take drugs before the incident and she showed no sign of having been under the influence when he first saw her on Saturday, though he says he wasn't satisfied he was dealing with "a competent person," KFOR reports. The lawyer says he has spoken to her boyfriend, who told him she has diabetes but isn't being treated for it, and that she also suffers from insomnia and didn't sleep for three days before the crash, per the Oklahoman. Coleman says the boyfriend has told him Chambers has attempted suicide before, but he doesn't believe she was trying to kill herself when she allegedly plowed into the OSU crowd.
