There have been at least 568 homicides this year, 172 more than this time last year, according to data kept by the Tribune.



As has been the case all summer, the overwhelming majority of attacks this past weekend occurred on the South and West sides. Only one person was shot north of Division Street, and that was the weekend’s first shooting Friday afternoon: A 23-year-old man wounded in the 5300 block of West Diversey Avenue.



Early Saturday, at least four people were shot when someone opened fire at a party in Englewood, police said. Three men were taken to hospitals after the house party in the 6800 block of South Emerald Avenue.



Later, a fourth man, 32, was taken to Holy Cross Hospital by friends with a gunshot wound to the arm. He initially told investigators he had been shot elsewhere in the city but later admitted he had been shot at the Emerald Avenue party, a law enforcement source said.



Sometime later, a 26-year-old man got to St. Bernard Hospital with a gunshot wound and said he had been shot in the 7100 block of South Vincennes Avenue. But police suspect he may also have been shot on Emerald Avenue, according to preliminary information from the law enforcement source.
