VISTA (CNS) - A former speech therapist at Rancho Buena Vista High School, who allegedly threatened co-workers while working at the northern San Diego County campus, pleaded not guilty Tuesday to charges of burglary, making criminal threats and vandalism.Arturo Avina, 33, was taken into custody by a SWAT team last Friday morning in connection with a series of menacing messages he allegedly sent to co-workers. The victims began receiving the messages last month, according to sheriff's Sgt. Shane Watts.Authorities released no details on the nature of the purported threats and did not specify the number of alleged victims. However, no students were involved in the threats, according to Lisa Contreras, director of communications for Vista Unified School District.RELATED: Former speech therapist at Rancho Buena Vista High School arrested``At no time were there any students who were in danger,'' Contreras said. Avina, who faces three years and eight months in prison if convicted, worked for the school district from August 2017 until January of this year, Contreras said.He's being held in lieu of 0,000 bail and is due back in court March 20 for a readiness conference. 1190

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

WASHINGTON — The Justice Department explored whether it could pursue either criminal or civil rights charges against local city officials as violence erupted night after night on the streets of Portland, Oregon.Federal officials researched whether they could levy criminal or civil charges against the officials, department spokesperson Kerri Kupec said.The research likely explored whether the rhetoric and actions of city officials may have helped spur the violence in Portland.The revelation underscores the Trump administration's effort seek action against those who officials believe may be helping contribute to protest-related violence.Kupec declined to comment on whether charges would be brought.According to The Associated Press, federal officials have reported that they were told by local law enforcement that they were explicitly told not to intervene at Portland's federal courthouse — the site of more than a hundred straight days of protest this summer. Protesters threw rocks and bottles at police and vandalized the building during several protests during that stretch.The Trump administration then briefly sent federal agents to the city in an attempt to quell the protests. Their initial presence in the city led to heightened tensions in mid-summer months.Portland Mayor Ted Wheeler said in a statement that it was "ridiculous" that the Trump administration was attempting to "distract" from its failures in handling the COVID-19 pandemic and west coast wildfires."The administration has made the cynical decision that the suffering of others is politically beneficial, regardless of the cost," he said, according to The Associated Press. "The people of this city — and throughout the nation — will not be intimidated, and I remain committed to doing my part as mayor to work with local partners to advance racial justice, and address the pandemic and economic challenges facing our community." 1923

WASHINGTON (AP) — After reports that U.S. government officials, including some White House officials who work in close proximity to President Donald Trump and Vice President Mike Pence, would be offered coronavirus vaccines as soon as this week, Trump said Sunday that most White House officials will have to wait to get a vaccine. Earlier, two people familiar with the matter confirmed that the newly approved vaccine from Pfizer would be made available to those who work in close quarters with the nation’s top elected officials. Meanwhile, public distribution is limited to front-line health workers and those in nursing homes and long-term care facilities. The officials say the move was meant to prevent more COVID-19 spread in the White House. Trump was briefly hospitalized after his diagnosis in October. 820
