Three men were shot, two of them fatally, Friday afternoon in north suburban Evanston, about a block from Evanston Township High School.
Officers responded to the shooting about 11:46 a.m. in the 1800 bock of Hovland Court and found three men with gunshot wounds, Evanston police said on Twitter.
Demarcus, 20, and Jose Sanchez Guerrero, 21, were in critical condition and later died, while a third man, an 18-year-old, had injuries that were not life-threatening, police said.
A gunman approached the three men, who were on a porch at the time, and opened fire, authorities said.
