DENVER, Colo. — A toddler, child, and three adults died in a house fire in Denver where arson and homicide are suspected, according to initial reports from the Denver Fire Department and Denver Police Department.Around 2:40 a.m. Wednesday, a Denver police officer called the fire department to report smoke along the 5300 block of N. Truckee Street, said Capt. Greg Pixely with the Denver Fire Department. This call was followed shortly afterward with several residents calling 911 about a fire in the neighborhood, which is near the southeast corner of Rocky Mountain Arsenal National Wildlife Refuge.Pixley said police arrived to the home, located at 5312 Truckee Drive, around 2:55 a.m. and made a valiant effort to try to help the people still inside from the "very significant fire."He said the officer who attempted to rescue people from the home was pushed back due to the heat from the fire.Pixley said according to initial reports, a toddler, child and three adults died in the fire and all five were found on the lower part of the home. Three people who had been on the second story of the building were able to evacuate on their own. Pixley said firefighters reported that the individuals jumped from the second story. Their injuries are unknown.DPD Division Chief Joe Montoya said evidence indicates this was an arson, so police will investigate the case along with the fire department. Montoya said he's unable to discuss details about the evidence as of Wednesday morning.Montoya said he believes there was one person who was near the front of the home whom police were able to retrieve but it was too late.Pixley said firefighters worked to reduce the threat of the fire spreading to the two neighboring houses. Both were damaged. 1753

Decades of underinvestment has left tens of thousands of schools across the country with inadequate ventilation systems, a problem that is now front and center in the debate to reopen schools during the pandemic.Nationally, 90 percent of schools fail to meet minimum ventilation standards. It’s an issue Dr. Joseph Allen has been sounding the alarm about since COVID-19 first shut down schools earlier this year.“We’ve chronically underinvested in our schools’ buildings,” said Dr. Allen who serves as the director of the Healthy Buildings program at the Harvard Chan School of Public Health.Dr. Allen and his colleagues have spent months analyzing school buildings, and back in June, they released a detailed 60-page report that school districts could follow in order to safely bring kids back into the classroom.In order to keep COVID-19 from spreading in schools, two things have to happen: everyone in the buildings must be wearing masks and school districts need to ensure buildings have proper ventilation, the report found.“If air is being recirculated and not filtered, all of that air that’s coming from one space and going to another could be potentially contaminated and spread the virus,” Dr. Allen said.But replacing decades-old ventilation systems that may not work properly is expensive and time-consuming. Because of that, Dr. Allen is recommending school districts also consider portable air cleaners for classrooms.Through his research, Dr. Allen found that if you can change the air in a classroom five times per hour, it cleans the air in that space every 12 minutes. However, the air cleaners must be equipped with a HEPPA filter in order to be effective.Even something as simple as opening windows could reduce the transmission of the virus.“If you look at the cases of spread in school right now, they all share common traits; it’s no mask-wearing and low to no ventilation. When we do that, we can guarantee there will be more cases,” he explained.Last week, the Healthy Buildings program also released a detailed portable air cleaner calculator. The tool allows school administrators to input the size of the classroom, even ceiling height, and then determine the kind of air cleaner that would most effectively keep COVID-19 from spreading.“It is critically important that we get kids back into in-person learning and we haven’t treated it as this national priority that it needs to be,” Dr. Allen added. 2438

Data scientist Youyang Gu, who is the creator of a website widely used to monitor the spread of the coronavirus, estimates that the spread of the virus is not quite as prevalent as it was in March and April, but added that the US is unquestionably in the midst of a second wave.Gu's model is among several the CDC uses to come up with official government projections on the spread of the virus.Based on a lack of testing early in the pandemic, Gu’s team estimates that there were around 250,000 new infections of the coronavirus each day in late March and early April. By July 1, that figure dropped in half.But in recent weeks, the spread of the virus has gained steam. Based on Gu’s projections, he estimates there are nearly 200,000 new infections of the virus each day. Based on Gu’s projections, he expects the virus to peak out with 265,000 new infections per day in early August.“We updated our infections estimate to closer match the observed data. We now estimate there to be around 180k new infections per day in the US, 4 to 5 times higher than the number of reported cases. Because we use only deaths in our model, we believe this estimate may still be an underestimate of the true prevalence,” Yu said.On Wednesday, there were more than 50,000 confirmed cases of the coronavirus, but Yu’s projection has the number of likely infections nearly four times higher.But Yu notes that there is a lag time between infections and when cases become fatal.To view the projections, click here. 1503

DENVER – A natural gas explosion caused at least one building to partially collapse Tuesday in Denver, injuring nine people. Simon Crittle, a spokesperson for Denver Health Medical Center, said two people were transported to the hospital by ambulance after the explosion and collapse. One of the people suffered traumatic injuries in the explosion. The other person was stable Tuesday afternoon.Crittle said that several other people were being treated at the scene of the explosion and collapse and that first responders were looking for other possible victims.Denver Fire Captain Greg Pixley said the explosion was reported at 1:15 p.m. Tuesday and said several buildings were damaged in the area. One person who had been trapped was rescued by firefighters.Pixley said that crews were working to put out an active fire at the scene in addition to working to reduce the chance of other explosions in the area and further collapses. He said there were no reported deaths as of 2:10 p.m.An Xcel Energy spokeswoman on scene said all of the company equipment is intact up to the meters, meaning the explosion was likely caused by a customer. Xcel is working to turn off gas remotely. The spokeswoman said the company has a distribution site at Lipan Street and Santa Fe Drive and staff at that location said they felt the explosion.Eileen Andrews, who owns the nearby Baker Neighborhood Market, said she saw a man run from the wreckage of the explosion who had his clothes blown almost entirely off his body and that the man suffered burns."I mean everything was exposed -- he barely had a couple strings left of his pants. He was completely exposed and said he didn't know what happened," she said. "It was just like the biggest, loudest boom I've ever heard."She said some men who had been working on her business' HVAC system ran over to help the man and another trapped woman.Another neighbor, Edward Scott, said he was on the phone with his insurance company at his nearby home when the explosion happened."[The insurance agent] was on the phone with me going, 'What happened, what happened?' and I said, 'I don't know, I think my house just blew up,'" Scott said.He said he was hit by wood debris from the explosion and that the shockwave from the blast was so intense he thought his own home had exploded. When he realized it was another home across the street, he said he walked over to the scene and saw a person rescued from the rubble."It was two people ... a lady. And then this guy picked her up and firemen carried her out of the house," Scott said. "And then the other one ... and they were boyfriend-girlfriend and they were both bartenders and they were sleeping."Scott said the woman had been looking for her cat, which was missing, but which was later discovered alive at the scene. 2827
