SAN DIEGO (KGTV) - Neighbors in Hillcrest say an abandoned church has become a campground for the homeless. The church sold the land to developer LMC North Park Holdings in 2018. They were still leasing it out until about a month ago. That's when residents say the homeless started moving in. "It's more or less the drug crowd, sex trafficking, stuff like that that winds up utilizing these areas," he said. The spot on Park Boulevard and Meade Avenue is boarded up, covered in graffiti, and littered with needles. On Tuesday, firefighters say transients smoking drugs started a fire at another vacant building a few blocks down. Passante says it's just a matter of time before that happens at the church. "It's the same people you see over and over and over again and most of them have some kind of mental illness," said Passante. "The quicker places like this can be demolished the less we'll have that problem.LMC North Park Holdings says they are aware of the problem and have hired 24/7 security. Our crews didn't see any security guards while out there for several hours gathering the story. They say they've been waiting on permits and have plans to start demolition by the end of the year. 1206

SAN DIEGO (KGTV) - More than 2,000 people whose lives have been affected by breast cancer started the Susan G. Komen 3-Day walk in San Diego Friday.One year ago, Leslie Heiser got the news she never expected to hear: she was diagnosed with breast cancer. After a year of treatment, doctors have declared her cancer-free. What started as simple motivation to get through tough days turned into what she believes will be a life-changing experience.The walkers participating in the Susan G. Komen 3-Day event will cover 60 miles in three days. All are doing it for different reasons: some walking in memory of loved ones, others showing support for those battling cancer. Heiser is doing the walk with her sister.RELATED: Rare breast cancer comes with unusual symptoms“She’s just been there for me every step of the way. And my biggest cheerleader from treatment to surgery. Those moments when you really need someone you can depend on, rely on, my rock," said Heiser.Each participant raised more than ,000 to do the walk. The money will go towards cancer research and medical expenses for those fighting the disease. Giving all those involved a sense of camaraderie as they flood the streets of San Diego with signs of pink while sending positive vibes to those who see them.Heiser adds, “it’s really about the experience of sharing it with other survivors and other people who have been impacted by breast cancer. And give everyone a chance of survival and hope.”RELATED: Breast Cancer Awareness Month events held in San Diego 1535

SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850
