A 15-year-old boy was wounded in a shooting Friday afternoon in Humboldt Park about a block from where a 45-year-old man was fatally shot hours earlier.

The boy was walking about 2:45 p.m. in the 1000 block of North Monticello Avenue when he heard gunshots and realized he was struck in his right side, according to Chicago police.

He was taken to Mount Sinai Hospital, where he was listed in good condition, police said.

Five hours earlier, a 45-year-old man was fatally wounded when he was shot in the back about a block south, police said.

Area North detectives were investigating both shootings.
