IMPERIAL BEACH, Calif. (KGTV) - Residents in one Imperial Beach neighborhood are hoping surveillance video will help put an end to an "endless" cycle of graffiti.In an alley off 14th Street, Gary Copeland looks at his neighbor's brand new fence and can only shake his head."It's disgusting we have to look at all this graffiti," said Copeland.On Monday around 4:30 a.m., a neighbor's motion-activated camera captured a man in a cap shaking a can of spray paint. In the next video recorded, one can hear the sound of spray paint before the man emerges from the dark. Hours later and blocks away, a camera in another alley captured a man without a cap spray-painting a similar tag on the wall of another home."It's a nuisance is what it is," said Copeland.Copeland's family has lived at his home for some four decades."You can see they've tagged my wall a few times. We've repainted, but they came back and re-tagged it," said Copeland.Copeland says his wall has been hit three times in the past six months."It's never-ending deal ... there's always tagging. Up and down the alley all these fences are tagged ... It takes your sense of living in a good home and neighborhood to feeling like you're living in a slum," said Copeland.If you have any information on the cases, call the Imperial Beach sheriff's station at 619-498-2400. 1339

In a new study of mask usage published by the American Institute of Physics, researchers found that if 70% of people wore surgical masks, the pandemic would be "eradicated."According to the article, which was published Tuesday, investigators with the Department of Engineering at the National University of Singapore looked at studies that reviewed N95s, surgical masks, and cloth masks to see how the mask's design, material, and capability of protecting people from the virus, was.Authors Sanjay Kumar and Heow Pueh Lee found that if 70% of people wore surgical masks in public consistently, the pandemic could be eradicated. Even cloth masks, which they found to be 30% effective, could lead to a "significant reduction of COVID-19 burden."The researchers analyzed that if masks are worn, it reduces the size of fluid droplets expelled from the nose and mouth, spreading the virus in the air. The investigators said small droplets traveled a more considerable distance and were in the air longer because they became aerosolized.According to the article, the researchers found that the N95s filtered out aerosol-sized droplets, and masks made with hybrid polymer materials effectively filter particles while simultaneously cooling the face. 1250
