When Nikolas Cruz started shooting last week, an armed deputy stationed at the Florida school rushed to the building.But instead of going inside, the officer waited outside for four minutes as the shooter killed students and faculty behind the walls, authorities said.School resource officer Scot Peterson "never went in" despite taking a position on the west side of the Building 12, where most of the carnage happened, Broward County Sheriff Scott Israel said Thursday.  485

While students in a South Carolina school participated in the National School Walkout this week, a custodian helped herself to their cash, police said.The incident occurred at Richland Northeast High School on Wednesday.Aisha Evans, a custodian at the school, went into a classroom while students were outside and rummaged through three book bags, the Richland County Sheriff's Department said.In all, Evans stole 0, the department said.The custodian was arrested soon afterward and charged with three counts of petty larceny.Evans, 32, was employed by Service Solutions, an agency that provides custodial services to the district's school.The agency terminated the woman, the school district told CNN affiliate WIS."On Thursday, March 15, Service Solutions notified Richland Two that Evans is no longer an employee of the company and was informed that she cannot come on any Richland Two property," Richland Two School District said in its statement to the affiliate.It's unclear whether Evans has retained a lawyer.The-CNN-Wire 1040

What you flush down your toilet could be brought back up to detect COVID-19.“Anytime that we are talking about poop, it’s a subject that either brings laughter or disgust; maybe a combination of the two,” said John Putnam with Colorado Public Health and Environment. Putnam is helping lead a team to test human waste to determine molecule levels linked with the coronavirus.“This gives you early warning that there could be an upsurge or a lessening of the disease in the community,” he said.Putnam says a person that’s been exposed to COVID-19 will pass the virus through their feces and possibly even urine. The waste eventually flows into sewer systems, which scientists will now collect.“We can then take a sample at a wastewater plant and send it to a lab,” he said.Labs at places like Metropolitan State University of Denver.“One of the advantages of this approach is that everybody in the community makes a contribution to the sewage,” said Rebecca Ferrell, Ph.D., a biology professor at MSU Denver.She says that when people get infected with COVID-19, they often shed the virus for several days before showing symptoms. Adding that this specialized stool sampling can alert scientists that the virus is in a community before people start getting sick.“It can give you extra warning about what might be happening in the hospitals then days maybe even a week later when people get sick enough that they are going to make demands on health care that you need to anticipate,” Ferrell said.With the cost to collect this data much cheaper than other options, Ferrell says more scientists are now teaming up with more wastewater treatment plants across the country.“These are the kinds of techniques where a relatively small investment early on can help us to get those resources to the right place and we can keep the mortality low,” she said.Hoping to get ahead of the pandemic, testing number two is becoming the number one priority for some scientists. 1965

When it comes to saving lives, seconds count. And now, thanks to improving technology, drones are proving to be a game changer in an emergency.Dozens of people’s lives were saved last year with the help of drones, according to drone maker DJI.  The company said from May of 2017 to April of 2018, 65 people were rescued with the help of a drone. DJI reviewed media reports to come up with that number and included documentation in its recent report released this year.Firefighters, search and rescue teams and other members of law enforcement are using drones to survey an area much faster from the air than people can on the ground.“During a search and rescue operation we can see body temperature, Romeo Durscher, DJI’s Public Safety Integration Director, said.Drones carry more than simple cameras. They are now built to send back infrared images.Aeryon Defense USA, of Denver, has drones that can carry upwards of four pounds of payload. The company sells drones that can be used by police agencies and the military."That allows you to hook in a medical kit, radio, food, water (or) ammunition to provide life sustaining equipment," said Mark Holden of Aeryon Defense USA. “We can carry water, enough for one day, food, even ammunition resupplies and some explosives as well.”The company’s drones can also be programed to single out a person moving in the camera’s view, but ignore a tree blowing in the wind or wildlife.“This is just the beginning. Everything we do is about taking the load off the end user. We want to replace human functions on the battlefield with a robot,” Holden said.Drones have helped find a woman with dementia in Randolph County, North Carolina. She had wandered into a nearby field. Drones dropped a life preserver to flood victims in Sichuan, China before rescue crews arrived to save the victims. An infrared camera-equipped drone located a crash victim who became unconscious after leaving his car to get help. A similar camera also was used to locate lost tubers on a river in Vestavia Hills, Alabama.Technology allows drones to carry more weight than before. In the last one-and-a-half to two years, drone makers have improved how drones fly in difficult weather conditions."Search and rescue operations rarely happen on a beautiful, no wind kind of day so we had to design them to withstand the snow, the wind, and the rain,” Durscher said.They can help save the lives of rescuers too."You know what's ahead of you. It can alert you of a big cliff or flooded river,” Durscher said.Drones used by most rescue agencies run as much as ,000 to ,000. 2642

WEST PALM BEACH, Fla. — President Donald Trump and First Lady Melania Trump arrived at Palm Beach International Airport Wednesday evening to spend the final Christmas of his presidency at Mar-a-Lago.The Federal Aviation Administration placed temporary flight restrictions around Mar-a-Lago's airspace on Tuesday and the Town of Palm Beach has placed checkpoints and closed roads around Mar-a-Lago.
