SAN DIEGO (KGTV) -- A 13-year old girl, waiting for her mother to pick her up in Grant Hill, was attacked by a knife-wielding man Friday afternoon.San Diego Police are now using surveillance videos in their search for the suspect, who yanked a gold necklace from the teen's neck before making his getaway near the intersection of 26th and K Street.The girl wasn't hurt, but parents like Elizabeth Alvarado, whose twin 12-year-old daughters walk by that same spot each day, are hoping he doesn't strike again.Alvarado saw surveillance video after the principal of her daughters' school sent parents a link, suggesting they talk to their kids about staying safe.Andy Trakas of Albert Einstein Charter Middle School said the girl who was attacked wasn't one of his students, but there are several other schools in the neighborhood."We decided to be very, very proactive because the safety of our students," said Trakas, adding that all children in the community are a concern."These things can happen anywhere," Trakas said. "They can happen in La Jolla, they can happen in City Heights, they can happen in Del Sur or La Mesa, whatever, but, by being part of the community we can all work together to make sure that our eyes and ears are open so we can find out who this person is and make this place a better, safer community for our kids."Trakas suggested parents talk to their kids about being aware of their surroundings and the importance of staying in groups, not alone, after school. San Diego Police stepped up patrols in Grant Hill after school and are following every lead to catch the thief.The suspect is describe as a black male five feet, eight inches tall with a stocky build who was wearing a plain black hooded sweatshirt, a black cloth covering the lower portion of his face and dark-colored pants. Authorities say the suspect was driving a white Hyundai Elantra  (pictured below.) 1919

Bulldozers also were being brought in.No structures were damaged nor were people injured. 951

SAN DIEGO (CNS) - Two researchers, including one from the Scripps Institution of Oceanography at UC San Diego, are in Antarctica in an effort to uncover the planet's oldest ice.The research trip is part of a cordial international race to find the ice, which will give geologists and climate scientists new insight into Earth's climate history. Scripps paleoclimatologist Jeff Severinghaus and University of Minnesota-Deluth geologist John Goodge arrived this month at an ice-drilling outpost at McMurdo Station, Antarctica.In October, Severinghaus and researchers at Princeton University published a study in the journal Nature analyzing a two-million-year-old ice core. However, that core was incomplete in its historical portrait of ancient air. According to Severinghaus' ice dating lab, the planet's oldest ice is roughly 2.7 million years old.RELATED: San Diego Zoo welcomes second rhino born via artificial inseminationSeaWorld frees whale tangled in 900 feet of rope off La JollaSan Diegans can fly over rush-hour traffic with FLOAT air service"That core ... was all broken up," Severinghaus said of the Princeton study. "It's like in archaeology when you find pieces of broken pottery you're trying to put back together."The two researchers are attempting to expedite the conventional ice drilling process, which currently takes roughly five years to dig two miles to the Antarctic ice shelf's deepest point. They believe their 50-ton drill could secure a 50-meter ice core with a full timeline of the continent's geologic development. Eventually, it could be used to dig to the continent's bedrock, which dates back 3 billion years.In addition to each other, geologists and climate scientists in the southern hemisphere are in a race against nature, as climate change continues to melt Antarctic ice and cause sea levels to rise, particularly on the continent's western edge, according to Goodge."The bigger question is what's happening in East Antarctica because there's a lot more sea level rise potential if it begins to melt as well," he said. "So we really need to understand what those conditions are."Once collected, the researchers will pack the ice samples in boxes until January, when the Antarctic sea ice thaws and the samples can be shipped to Port Hueneme in Ventura County. They will then be transported to the National Science Foundation's Ice Core Facility in Lakewood, Colorado, for study in late spring. 2439

SAN DIEGO (KGTV) -- A 96-year-old family secret reveals a piece of the Carlsbad school district’s history. Florence Oliver has lived in San Diego her whole life."I was born at SD General at that time, but of course I don't remember it!" The family settled down in Carlsbad, and for Florence, family is everything. For the last century, her family hung on to another memory. A brass bell from the Carlsbad School which rung daily for class.In 1922, Florence's uncles stole stole the bell to pull off a prank on her mother's wedding night. "They hung it, in those days you had those wire springs on bed to hold mattresses, they hung it underneath, no one knew… so the bell really rang loud!"Rather than return the bell, it stayed in the family - first handed down to Florence's oldest brother, and then the next brother, and eventually to her."What does it mean to me, it's just a piece of our life, and it's gone through our family, it's like it's related."One day, Florence had a conversation with her niece. "She said Dad used to go in the garage and she told me that bell needs to go home, that would make him very proud."So last month, Florence made good on her promise. Nearly 100 years later the bell is back where it belongs. 1239
