Two men were wounded by gunfire Friday night in the Hermosa neighborhood on the Northwest Side.

At 6:40 p.m., the 69-year-old and 40-year-old were looking into a possible burglary at a building in the 4500 block of West Palmer Street, according to Chicago police. An unknown person began shooting at them, striking the 69-year-old in the left shin and grazing the other man’s right thigh.

The 69-year-old was taken to Norwegian American Hospital in good condition, police said. The younger man declined medical treatment.

Area North detectives were investigating.
