When authorities arrived Friday to arrest a 15-year-old in Florida after threats to commit a school shooting showed up on a video game platform, he told them he was joking, they said."I Dalton Barnhart vow to bring my fathers m15 to school and kill 7 people at a minimum," the boy wrote using a fake name, according to a Volusia County Sheriff's Office report.The teen is one of more than two dozen people who have been arrested over threats to commit mass shootings since 31 people were killed in one weekend this month in shootings in El Paso, Texas, and Dayton, Ohio.The raft of cases follows a directive by the FBI director immediately after the two early August massacres for agency offices nationwide to conduct a new threat assessment in an effort to thwart more mass attacks.The FBI was concerned that US-based domestic violent extremists could become inspired by the attacks to "engage in similar acts of violence," the agency said in a statement.Indeed, it was a tip to the FBI that sent sheriff's deputies to the home of the Florida teen, the sheriff's report states. CNN is not naming him because he is a minor.A woman who said the boy is her son told authorities that kids say things like that all the time and her child should not be treated like a terrorist, body-camera footage from the arrest shows.Joke or not, such comments are a felony in Florida, the sheriff's department wrote on its Facebook page."After the mass violence we've seen in Florida and across the country, law enforcement officers have a responsibility to investigate and charge those who choose to make these types of threatening statements," the post states.Here are the known threats with publicized arrests that law enforcement agencies have investigated since the Dayton and El Paso shootings:August 4: A man from the Tampa area called a Walmart and told an employee he would shoot up the store, the Hillsborough County Sheriff's Office said in a statement. The man faces a false threat charge.August 7: Police in Weslaco, Texas, arrested a 13-year-old boy. The boy will face a charge of terroristic threat for making a social media post that prompted a Walmart to be evacuated, police said on Facebook. The boy's mother brought him to the station.August 8: A man is accused of walking into a Walmart in Missouri equipped with body armor, a handgun and a rifle less than a week after a gunman killed 22 people in a Texas Walmart says it was a "social experiment" and not intended to cause panic. The 20-year-old was charged with making a terrorist threat.August 9: A 23-year-old Las Vegas man is charged with possessing destructive devices after authorities found bomb-making materials at his home. The FBI says he was 2721

WASHINGTON, D.C. – Amid the bright orchids of the U.S. Botanic Garden sits a 200-year history of protecting America’s most fragile plants.“We're a living repository for rare and endangered plants,” said Saharah Moon Chapotin, director of the garden.The U.S. Botanic Garden is the oldest one in the country, an idea envisioned by George Washington and Thomas Jefferson. It’s about to celebrate its 200th year. About 60,000 plants, lying within several acres in the heart of Washington, D.C.Conservation at the garden is always in season.“Many of our plants are rare and endangered and we are providing a home for them,” Chapotin said.Here in the U.S. there are 1,300 species that are considered threatened or endangered. Nearly 20 percent of those are plants adding up to hundreds of flora on the brink.Some already fell off the cliff, like Hawaii’s “Cabbage on a Stick.” Because of overdevelopment, the insect that pollinated it disappeared and in 2014, the plant went extinct in the wild, too.There are others endangered, too, like a cactus from Arizona and bushes which are native to Florida. Endangered plants don’t always get the kind of attention endangered animals do.“Often people do think about animals they have faces and they're sort of cute,” USBG deputy director Susan Pell. “So, we kind of think people generally can sort of sympathize with them a little bit more, than maybe with a plant that they're not familiar with.”At the garden, they emphasize how much plants are tied to the habitat of endangered animals, at risk from invasive species, development and climate change.“They're really interconnected and so I think plants are a fundamental part of conserving environment and conserving habitats,” Chapotin said. “And if you just focus on conserving the animals you're leaving out a huge part of the equation in terms of the plants.”That all adds up to a continuing mission of saving plants there in the hopes of one day taking those that are now extinct outside the walls and reintroducing them back to Mother Nature. 2049

US and Chinese negotiators have agreed in principle to the "phase one" trade deal, according to a person familiar with the talks.President Donald Trump's trade team was due to brief the President on the agreement during a mid-afternoon meeting at the White House. He will need to sign off on the plan before it's final.Trump had already announced the broad contours of the "phase one" deal in October, and the two sides have been haggling over specifics since then. The "phase one" deal does not address the major structural changes to China's economy that Trump has sought.The terms of the agreement include a delay in new tariffs on 647

Whether you are an expectant parent or grandparent, one thing you might not think about before the baby arrives is preparing your dog for the new arrival. That’s where a "dog doula" can help.What should have been a happy time to bring a new baby into the family was a bit stressful for Laurisa Truemper. She was nervous about introducing her dog to her baby, Hazel."Dogs are a part of the family so when you get a new member, you don’t think of getting rid of a family member," Truemper said. "You are just hoping everyone is going to get along.”Her dog Ruby has always been a good dog. But Tanya Lim, the owner of Family Pupz in Denver, says a dog is still a dog. We should never assume it won’t bite.Lim calls herself a "dog doula.""As a doggy doula I support dog training for expecting families,” Lim said.Lim tells her clients to observe how their dog behaves around the baby.If it yawns, looks away, licks its lips, its ears go up or it has tension in the face, those are all signs of aggression or anxiety."A lot of times when there is a bite, people will say the bite came out of nowhere," Lim says. "However, if you observe footage of the dog you will see the dog was giving warning signs.”To avoid a scary situation, Lim says to set up baby gates around the house. Never leave the baby and dog alone together. Also, place the dog crate in another room away from the baby. And never yell at the dog when you see aggressive behavior.After a few easy adjustments given by Lim, Truemper noticed a big difference in behavior from Ruby. But she understands she will have to help her daughter Hazel act safely around Ruby as well. 1644
