SAN DIEGO (KGTV) - Students at three Vista Unified School District secondary schools are pivoting to virtual learning on Thursday.The district confirmed Vista High School, as well as Roosevelt and VIDA middle schools, are making the switch after a positive COVID-19 case at each school.According to rules the district's School Board adopted in late October, if one school has two or more positive cases, the whole school will shift to virtual learning for 14 days. If three secondary schools see one case each, the schools would have to do the same -- which is what happened in this case of Vista High, and Roosevelt and VIDA middle schools.The schools are expected to return to in-person learning on Dec. 1, according to the district website.Three other Vista Unified schools -- Rancho Buena Vista High School, Madison Middle School, and Vista Magnet School -- also went back to virtua

SAN DIEGO (KGTV) — San Diego Police say possible human remains were discovered in a Fiesta Island fire pit early Thursday.Just after 10:30 a.m., a man on the east side of the island flagged down San Diego Lifeguards after making the grim discovery. Officers responded and sent an image to a forensic anthropologist, who confirmed the remains were possibly human.ABC 10News spoke to the man who made the discovery. Dan Conklin says he was hoping to spend the day on Fiesta Island and was planning to grill some hot dogs when he parked his van near the fire pit. Conklin says he noticed a lot of trash surrounding the pit and some extra wood, so he decided he would stay. When he started cleaning up, he says, he noticed what looked like human remains. "I kept thinking it was a joke, something to do with Halloween, it had to be a mannequin or a dummy or something that you put on your porch or something," said Conklin. Conklin says he flagged down a lifeguard in the bay who then called police. Conklin says when he arrived at the pit, it was still smoldering. No other details surrounding the find were given in order to protect the investigation, police said.SDPD Homicide Unit officers, the Metro Arson Strike Team, and the county Medical Examiner will determine if the remains are human and the circumstances around their discovery.Anyone with information is asked to call SDPD's Homicide Unit at 619-531-2293 or Crime Stoppers at 888-580-8477. 1457

SAN DIEGO (KGTV) - Since the deadly shooting in Parkland, Florida last month, the San Diego County District Attorney's office has seen 19 cases of local school threats.Nine juveniles so far have been charged criminally, according to District Attorney Summer Stephan."We can't assume that the threat is a joke," Stephan said.Stephan said that even though there is not an intent to carry out a school shooting, the person behind a social media threat could face a felony charge if they determine there is an intent to cause fear.Students could receive consequences ranging from custody time, community service, additional mental health services, restorative justice, or access to social media taken away ordered by a judge.San Diego County school threat timeline:"When they hear the judge mention taking their social media away, you can see their faces change over that," Stephan said. "It's important that parents and [the] community really talk to their kids."Stephan said investigators look at a number of factors when determining which cases rise to the level of charges."We have to look at do they have access to weapons? Have they acquired weapons recently? Have they visited websites that indicate a fascination with school shootings and violence?" Stephan said.Of the 19 cases, Stephan said eight cases "did not rise to the level" of criminal charges. However, she said they will work with the minor and the family to prevent a similar situation in the future. A couple of the other cases are still under investigation. 1533

SAN DIEGO (KGTV) - Scientists at the Hubbs-SeaWorld Research Institute are working to replenish the California Halibut population.In October, they released 2,300 juvenile halibut into Mission Bay. Those fish were bred, born and raised at the institute. They hope it's just the start of a robust replenishment program."The species is pretty heavily depleted and for that reason, they're a good candidate to help boost the species," says Mark Drawbridge, the Institute's Director of the Sustainable Seafood Program.Recent surveys show the California Halibut is down to 14 percent of what its population should be. The most severe drop has come in Southern California.Hubbs hopes it can replicate the success it had with the White Seabass. It has released nearly 2.5 million seabass into the wild in the last 35 years."A lot of the process is transferable from one species to another," says Drawbridge.The Dick Laub Fisheries Replenishment Program oversees every step of the process, from breeding to release. Drawbridge says they've seen success in every phase so far."Our survival rates from egg to juvenile stage are typically 20 percent or higher," he says. "Compare that to the wild, where it would be a fraction of a percent. That's more than adequate to produce tens of thousands of fish."The next step is seeing how the halibut survive in the wild. The Institute put stainless steel trackers in each fish and will monitor them over the next few years.The program is funded through private donations, many of which come from fisherman who need a healthy halibut population to make a living. 1602

SAN DIEGO (KGTV) — Seven people are dead after contracting a flesh-eating bacteria linked to black tar heroin use in San Diego.County health officials said nine people who injected black tar heroin were admitted to county hospitals between Oct. 2 and Nov. 24 with a bacterial infection called myonecrosis, which is a severe soft tissue infection that destroys muscle. Of those victims, seven have died. The patients range in age from 19 to 57 years old.RELATED: Sixth death reported during San Diego's current flu season“People who use black tar heroin are not only at higher risk of dying from an overdose, but also more prone to developing myonecrosis and wound botulism,” said Wilma Wooten, county public health officer.One confirmed case of wound botulism linked to black tar heroin use was also reported in October — the first confirmed case in the county this year.Wound botulism, which attacks the body’s nerves, is also linked to heroin use. People who inject illicit narcotics like black tar heroin are at a higher risk of developing both infections, the county says. Last year, seven cases of wound botulism were reported in the county.RELATED: Dozens arrested after drug bust in East VillageIn Southern California, 13 probable and confirmed wound botulism cases — most of them linked to black tar heroin — have been reported since Sept. 1, the county says.The source of the black tar heroin linked to the infections is unknown and officials are currently investigating. Additional cases may be reported.Symptoms of severe myonecrosis can include severe pain; pale skin that quickly turns gray, dark red, purple, or black; foul-smelling blisters; fever; and increased heart rate. Severe instances can spread throughout the body and cause shock, leading to amputations or death if untreated.People who are experiencing drug addiction or substance use disorders are encouraged to seek help through the county's crisis line at 888-724-7240. 1955
