A flurry of sirens moving toward the intersection of Garden and Arrellaga streets last night followed a stabbing in Alice Keck Park Memorial Gardens. Officers arrived at the park at about 9 p.m., where they found a group of people standing near a 20-year-old who had been stabbed in the left side of his abdomen. The group told police that they had been confronted by two people they did not know. According to the police account of events, an argument ensued and, when the victim challenged them to a fight, one of the two strangers pulled out a knife and stabbed. The victim was admitted to Santa Barbara Cottage Hospital. The victim, however, told the Independent that he had not, in fact, challenged anyone to a fight and that the police report was incorrect.
