PHILADELPHIA, Pa. – Within a series of unfinished walls, Tom Stefanko oversees hundreds of construction workers every day, all of them wearing what looks like an old-school pager. Yet, the technology involved is new.“I think it gives workers a little bit of comfort,” Stefanko said.The devices are proximity tracers, designed to make sure workers on construction sites remain socially-distant during these pandemic times.“If I was in contact another person, it would start beeping red,” Stefanko said. “And if I stayed there longer, it progressively beeps louder.”While they alert workers that they’re too close to one another, the proximity tracers also record that data, in case a worker later ends up testing positive for COVID-19.“It provides the ability to have a real-time alerting system and then also be able to go back historically and see who's been in contact with whom to do the contact tracing,” said Robert Costantini, CEO of Triax Technologies.The company began to develop the proximity tracers when the coronavirus outbreak began.“The stakes are really high, if you get it wrong,” Costantini said. “I mean, workers could be infected. You can shut your site down. The cost can be enormous.”The contact tracers, though, cost about a dollar a day, per worker. More than 15,000 of them are now in use on more than 70 construction sites around the country, including the 1 million square foot building that Tom Stefanko and his team are working on in Philadelphia.“We have a thousand tags here on site,” Stefanko said. “Most workers just keep it on their hardhat. And take it with them as they come and go – so, making it as part of their PPE.”It’s personal protective equipment that is now a requirement to try and keep COVID-19 out of their workforce. 1772

Police are investigating a car crash that killed a zebra in Chandler, Arizona on Wednesday morning.Several area residents posted in a neighborhood Facebook group about the crash around 6 a.m. local time, including rumors that the animal may have escaped from the Ostrich Festival grounds nearby. Chandler Police confirmed that a vehicle struck a zebra. They say the zebra, who was from the Ostrich Festival, was killed in the crash. The driver suffered minor injuries. Scripps station KNXV in Phoenix on the scene caught crews towing away a white SUV with front-end damage. A zebra was also spotted in a pen with ostriches on a property off the road, but it appeared to be uninjured.  712

PHOENIX, Ariz. -- New witness video shows Phoenix police pinning down a 28-year-old man on a scorching summer street just minutes before he became unresponsive and died.Ramon Timothy Lopez was the father of two children, including a newborn baby. Lopez had been diagnosed with paranoid schizophrenia, according to his girlfriend. He worked as a truck driver, and he lived less than a mile from where he encountered police on August 4.The witness, who captured about 20 seconds of cell phone video, said she stopped with other traffic as an officer chased Lopez back-and-forth across 51st Avenue near Indian School Road at about 10:30 a.m. that day. The woman, who also lives in the Maryvale neighborhood, asked KNXV not to use her name. She felt the first officer was overly aggressive toward Lopez."[I] felt he was using a lot of force to slam his body into the ground," the woman said. "The gentleman seems like he was still struggling, but at that point, it seemed like he just didn’t want his face smashed on the asphalt. It was super hot.”Minutes earlier, police were dispatched to a report of a man looking into car windows in a nearby parking lot. Phoenix police say Lopez saw the officer approaching him when he ran into a liquor store, threw a drink at the officer, and ran away into the road."The officer was by himself and when he grabbed hold of Lopez, they both fell onto the hot asphalt and both could have been struck by vehicles on 51st Avenue," Sgt. Mercedes Fortune said in an email to KNXV.Once other officers arrived, "Ramon refused to cooperate and continued to kick and pull away from officers," Fortune added.The witness video, from the moving car, showed one officer holding Lopez's feet to the ground. A second officer appeared to kneel on Lopez's back and a third officer was crouching near his upper body. It's unclear whether he was also on top of Ramon."He did have his left knee in the midst of his back and shoulders," the witness said. "[The officer] had [Ramon's] arms pressed against the tops of his shoulders and his legs were actually on his hand, so at that point, [Ramon] was restrained, and [the officer] was still put in quite a bit of force."Lopez appeared to be holding his head off the pavement, but he was not moving otherwise. Police said they found no drugs or weapons on Lopez.Police say they put Lopez in the back of a police car before he became unresponsive. He was taken to the hospital and pronounced dead."Officers did not place their knee(s) on Ramon's neck and at no time was his airway obstructed," Fortune said. She added that Ramon was laying on the roadway for a minimal amount of time.Asphalt on a 100-degree morning in Phoenix can become hot enough to cause serious burns on human skin.Fortune also said it would be "highly irresponsible" to assume the cause of death. According to the Maricopa County Medical Examiner website, the autopsy results are still pending.The witness who spoke to KNXV said she also called the Phoenix Police Department to report concerns about what she saw. She said a sergeant returned her call."He let me know he reviewed the body cam and didn't see anything that I was reporting," she said. "At that point, he couldn't really help me with anything, and it wasn’t, you know, his department."She's still hoping for answers and closure for Lopez's family and her entire neighborhood."I’m supposed to depend on these police officers to protect us, and when I see situations like this, it’s just hard to know where to put the trust at this point," she said.Phoenix police tell KNXV they will release their bodycam video of the arrest and in-custody death next week.This story was originally published by Melissa Blasius at KNXV. 3723

PHOENIX (AP) — The 5,200 active-duty troops being sent by President Donald Trump to the U.S.-Mexico border will be limited in what they can do under a federal law that restricts the military from engaging in law enforcement on American soil.That means the troops will not be allowed to detain immigrants, seize drugs from smugglers or have any direct involvement in stopping a migrant caravan that is still about 1,000 miles from the nearest border crossing.Instead, their role will largely mirror that of the existing National Guard troops — about 2,000 in all — deployed to the border over the past six months, including providing helicopter support for border missions, installing concrete barriers and repairing and maintaining vehicles. The new troops will include military police, combat engineers and helicopter companies equipped with advanced technology to help detect people at night.RELATED: Christ United Methodist Church at capacity, needs help preparing for incoming migrant caravanThe extraordinary military operation comes a week before the Nov. 6 midterm elections as Trump has sought to transform fears about the caravan and immigration into electoral gains. On Tuesday, he stepped up his dire warnings, calling the band of migrants fleeing poverty and violence in Central America an "invasion.""Our Military is waiting for you!" he tweeted.Traveling mostly on foot, the caravan of some 4,000 migrants and a much smaller group of hundreds more are still weeks, if not months, before reaching the U.S. border. Thousands have already dropped out, applying for refugee status in Mexico or taking the Mexican government up on free bus rides back home, and the group is likely to dwindle even more during the arduous journey ahead.Another smaller caravan earlier this year numbered only a couple hundred by the time it arrived at the Tijuana-San Diego crossing.And despite the heightened rhetoric, the number of immigrants apprehended at the border is dramatically lower than past years. Border Patrol agents this year made only a quarter of the arrests they made in 2000 at the height of illegal immigration, when the agency had half of the staffing it does today. The demographics have also drastically changed, from mostly Mexican men traveling alone, to Central American families with children.RELATED: Wait times for citizenship applications stretch to 2 yearsMigrants arriving at the border will now see a sizable U.S. military presence — more than double the 2,000 who are in Syria fighting the Islamic State group — even though their mission will be largely a support role.That's because the military is bound by the Posse Comitatus Act, a 19th- century federal law that restricts participation in law enforcement activities. Unless Congress specifically authorizes it, military personnel can't have direct contact with civilians, including immigrants, said Scott R. Anderson of The Brookings Institution.Instead, the large troop deployment will be limited to performing similar support functions as the National Guardsmen and women Trump has already sent to the border.These include 1,500 flight hours logged by about 600 National Guard troops in Arizona since they were deployed this spring. Members of the guard have also repaired more than 1,000 Border Patrol vehicles and completed 1,000 hours of supply and inventory, according to Customs and Border Protection.In one case, a group of Border Patrol agents tracking drug smugglers in the remote Arizona desert in August called on a National Guard helicopter to keep an eye on the suspects and guide agents on the ground until they had them in custody. That operation resulted in several arrests and the seizure of 465 pounds of marijuana.In addition to the 5,200 troops being deployed this week, the Pentagon has put another 2,000 to 3,000 active-duty troops on standby in case they also are needed at the border, a U.S. official said Tuesday, speaking on condition of anonymity to discuss a detail that has not been publicly announced.The troops were being sent initially to staging bases in California, Texas and Arizona while Customs and Border Protection works out precisely where it wants the troops positioned.It remains unclear why the administration was choosing to send active-duty troops given that they will be limited to performing the support functions the Guard already is doing."Sending active military forces to our southern border is not only a huge waste of taxpayer money but an unnecessary course of action that will further terrorize and militarize our border communities," said Shaw Drake, policy counsel for the American Civil Liberties Union's border rights center at El Paso, Texas.The California National Guard has pledged up to 400 troops to the president's border mission through March 31. Jerry Brown, the only Democratic governor in the four states bordering Mexico and a frequent Trump critic, conditioned his support on the troops having nothing to do with immigration enforcement or building border barriers.Brown said the California troops would help fight transnational criminal gangs and drug and firearms smugglers.In New Mexico, 118 Guard troops have been helping with vehicle maintenance and repair, cargo inspection operations, surveillance and communications.Texas Gov. Greg Abbott pledged 400 troops to the border in April. Maj. Gen. John Nichols, the head of the Texas National Guard, told Congress in July that his troops served in a "variety of support roles," including driving vehicles, security monitoring, and administration. 5568

PHILLIPS STATION, Calif. (AP) — Winter storms have blanketed California's Sierra Nevada in snow, but the drought-prone state is still off to another drier-than-normal start to the crucial wet season, state officials said Thursday.California water managers said Thursday the Sierra snowpack is only 67 percent of normal in this winter's first manual measurement. The amount of snow is measured monthly through the winter at more than 260 locations to help water managers plan for how much they can deliver to customers later in the year.As snow in the Sierra melts in the spring and summer, it flows into reservoirs for storage and provides drinking and agricultural water for much of California. The snowpack supplies about 30 percent of the state's water needs, according to the Water Resources department.WEATHER: Check the 10News Pinpoint ForecastPrecipitation has bounced up and down as the state continues to recover from a devastating drought that led to tight water restrictions for residents and farmers. Persistent drought has also dried out trees and brush, contributing to severe wildfires.Gov. Jerry Brown declared a formal end to a three-year drought emergency in 2017, but said water conservation efforts must continue."The last few years have shown how variable California's climate truly is and what a profound impact climate change has on our water resources," Karla Nemeth, director of the California Department of Water Resources, said in a statement.More than 92 percent of California is considered abnormally dry, or in moderate, severe or extreme drought, according to the U.S. Drought Monitor, a project of several federal agencies and University of Nebraska-Lincoln. That's up from 56 percent a year ago.California typically gets about two-thirds of its annual rainfall between December and March.A storm is expected to drop snow and rain on much of Northern California, including the Sierra, this weekend and into next week, the National Weather Service said Thursday.At Phillips Station, a water measurement site near Lake Tahoe, officials on Thursday measured 25.5 inches (65 centimeters) of snow and a snow water equivalent of 9 inches (23 centimeters) — about 80 percent of average for the early January survey."We still have three wet season months ahead of us, so there's time for the snowpack to build and improve before it begins to melt, which usually starts happening around April 1," Michael Anderson, climatologist for the water department, said in a statement. 2506
