With his spring break just hours away, Central Michigan University student James Eric Davis Jr. was with his parents in a campus residence hall Friday morning when he shot them dead, police say.Davis Jr., 19, shot and killed his mother and father in the dorm on the northwestern edge of campus Friday morning, authorities said, leading to an hours-long manhunt that ended with his arrest early Saturday.It was the nation's 12th school shooting this year.It's not immediately clear what led to the shooting or why the parents, James Eric Davis Sr., 48, and Diva Jeenen Davis, 47, were on campus in Mount Pleasant, a roughly four-hour drive from their Chicago-area home.But authorities said the student had an encounter with police hours earlier -- on Thursday evening when he was taken to a hospital for what officers believed was a bad reaction to drugs, campus police Lt. Larry Klaus said.And the parents may have been intending to pick up their son for spring break, said Andre Harvey, mayor of the Chicago suburb of Bellwood, where the elder Davis was a part-time officer."The family is in shock and trying to piece everything together," a relative, speaking on condition of anonymity, told CNN.Arrest comes after midnightDetails about the younger Davis' arrest weren't immediately clear. But it came early Saturday after someone reporting seeing him on or near campus, the university said."The suspect was seen and reported by an individual on a train passing through the north end of campus shortly after midnight," the university said in an online statement. "Law enforcement personnel responded and arrested the suspect without incident."The shooting, which happened on Campbell Hall's fourth floor around 8:30 a.m. Friday, disrupted a campus that otherwise was winding down for a nine-day spring recess beginning Saturday.Students were told to stay in campus buildings until the afternoon when police officers started allowing them to leave. People trying to enter the campus to pick up students for spring break were initially directed to a campus-area hotel, where the university asked them to wait for instructions.The university's men's basketball home game Friday against Western Michigan University was rescheduled for Saturday morning at a neutral site, Northwood University, where it will be closed to the public except for family members, the Mid-American Conference said.The university, with roughly 23,000 students, is about a two-hour drive northwest of Detroit.Student had 'drug-related' incident earlier, police sayCampus police spoke with Davis Jr. on Thursday night, Klaus said during a news conference."At some point in the evening, he was transported to McLaren Hospital due to what the officers believed may be a drug-related-type incident, an overdose or a bad reaction to drugs. At that point he was released to the hospital staff," Klaus said.As for Friday's shooting, "we're calling it a family-type domestic issue at this point," he said.The victimsThe Davis family was from the Chicago area. Davis Jr. graduated from a high school in Plainfield, Illinois, about 30 miles southwest of Chicago, in 2016, said Tony Hernandez, Plainfield school district spokesman.His father was a part-time police officer in Bellwood for 20 years and assisted the department on special occasions."He was always there when you asked for him to be there," Bellwood police Chief Jiminez Allen said.The elder Davis was a pillar of the community, which has 20,000 residents, and was beloved by friends and neighbors, said Harvey, Bellwood's mayor.An Army veteran, he was also a police officer employed at the Jesse Brown VA Medical Center in Chicago, said center director Marc Magill."The staff at Jesse Brown VAMC take enormous pride in the care we provide our Veterans, and this situation hits us especially hard. We are currently providing grief counseling for staff," Magill said.The violence came more than two weeks after a shooting rampage at Marjory Stoneman Douglas High School in Parkland, Florida, left 17 people dead and spurred a national debate over gun control.Nine weeks into the year and 12 school shootingsCNN's calculation of the number of school shootings include shootings on school property that involve one or more victims and other factors. These can also be domestic violence incidents.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company. All rights reserved. 4423

While experts are encouraged by early vaccine data, many still say there is a way to go before life returns to normalcy."Operation Warp Speed," is a Trump administration effort to develop and deliver a safe and effective COVID-19 in the coming months. The administration's goal is to make initial doses available by January 2021.The vaccine will initially be rationed while drugmakers produce more doses. Healthcare workers, people in nursing homes, first responders and those with high-risk health conditions will likely be the first people eligible to receive the vaccine. According to Dr. Anthony Fauci, the director of the National Insitute for Allergies and Infectious Diseases, the rest of the general population won't be able to receive the vaccine until later in 2021.Pfizer and Moderna have both announced that their vaccines are on track for potential emergency authorization from the Food and Drug Administration. But there are several other candidates that could also get approval soon — and could potentially overtake the market.Both Pfizer's and Moderna's vaccine candidates require two shots, which need to be taken 28 days apart. But health experts believe that if a single-dose vaccine gets approval, it could quickly become the standard for worldwide vaccination."So, if you can get a vaccine out there that actually requires only one dose, it could quickly overtake the market," said Dr. Marcus Schabacker the President & CEO, of Emergency Care Research Institute.Health experts are also encouraged that there are several vaccine candidates in the final stages of testing — they believe that more potential vaccines reduce safety risks."We have a lot of people in the world. We need to vaccinate in different countries under different criteria, and you always run the risk that there's something in the Pfizer vaccine that someone's allergic to that isn't in the Madonna vaccine," said Dr. Jill Roberts, an associated professor as USF Health.One question that hasn't yet been answered is how the vaccines will stand up to the newly infected."So if you're turning positive today, we know you are exposed to somebody that had COVID, and we vaccinate you today — will that actually prevent you from developing severe disease?" Roberts said.Merck is another U.S. based pharmaceutical company that is working on a single-dose COVID-19 vaccine. That vaccine is currently in early testing overseas. 2422

With its low air pressure, Hurricane Michael unofficially sits as the third-strongest landfalling hurricane to strike the United States. Having such a tremendously low air pressure typically causes storms to have strong winds, and Michael was no exception. Hurricane Hunters from the Air Force and NOAA estimated Michael's lowest pressure was 919 MB at landfall. The only two hurricanes with a lower pressure at landfall to hit the United States were the Labor Day Hurricane of 1935 and Camille of 1969.Also based on estimates, Michael had top winds of 155 MPH, which is just below Category 5 status. Based on top winds speeds, Michael was tied for the sixth-strongest landfalling hurricane in US history, tied with Hurricane Maria in 2017 and "Guam" in 1900. In terms of air pressure, Michael was 1 MB stronger than Katrina in 2005 and Maria in 2017 at landfall, and 3 MBs stronger than Andrew of 1992. Michael's top winds at landfall were well ahead of Katrina's top winds at landfall of 130 MPH, on par with Maria's top winds at landfall of 155 MPH, but below Andrew's top winds of 165 MPH.But in the immediate aftermath of Andrew, it was declared a Category 4 hurricane at landfall. It was not until years later when the National Hurricane Center concluded that winds in Andrew were greater than 157 MPH, marking the only Category 5 hurricane to strike the US since Camille in 1969. Like Andrew, Michael continued to strengthen all the way until landfall. In just three days, the storm went from a tropical storm to a high-end Category 4 hurricane. Other reasons Micheal will be notable:- Michael was just the sixth hurricane of at least Category 4 strength to hit Florida since 1950.  1752

With California hospitals dealing with an extreme number of patients, nurses are terrified of what’s next.It comes as California hits 2 million infections just 44 days after reaching 1 million. Hospitals in California have been pushed to the brink, and it’s expected to get worse as people travel and gather for Christmas and New Year’s.The state is urgently searching for 3,000 temporary medical workers to meet the demand, focusing on nurses trained in critical care. Hospitals are also confronting the shortage by trying to free up staff any way they can, including postponing certain medical procedures.The state has also temporarily loosened some restrictions. Typically, California requires one nurse for every two ICU patients. Regulators have temporarily relaxed that requirement to one nurse for every three ICU patients.The state has sent more than 600 temporary healthcare workers to hard-hit counties from the National Guard, the California Health Corps, and other partnerships, but officials are still looking for more.State officials have even started reaching out to other countries like Australia and Taiwan to get much-needed medical workers.Elected leaders and health officials across the U.S. are asking people to stay home for the holidays while also trying to show the public that the COVID-19 vaccines trickling out to health care workers and nursing home residents are safe.The Associated Press contributed to this report. 1453

WEST POINT, N.Y. (AP) — More than 70 West Point cadets have been accused of cheating on a math exam taken online when they were studying remotely because of the coronavirus pandemic.A spokesman at the U.S. Military Academy says 55 cadets admitted cheating on the calculus exam in May. Most of them have been enrolled in a rehabilitation program and will be on probation for the rest of their time at West Point.The cheating came to light when instructors saw irregularities while grading the exam. One of the students was a sophomore, and the 72 others were freshmen in a class of 1,200 West Point cadets.According to the Associated Press, once an honors committee completed their investigation into the matter, two cases were dropped due to lack of evidence, four cases were dropped after cadets resigned, and three cadets admitted to cheating but aren't eligible for the rehab program.Several over cadets will face hearings with the administration to see if they will be penalized or expelled, the AP reported.According to the AP, the only other cheating scandal to occur at West Point happened in 1976 when 153 cadets were expelled or resigned for cheating on an electrical engineering exam.More than 90 of those caught cheating in 1976 were reinstated and allowed to graduate, the AP reported. 1305
