Two teenagers were wounded in separate shootings in Philadelphia.
The latest victim was shot in the back while inside a home.
It happened in the 1500 block of Adams Avenue in Frankford just before 1:30 a.m. on Monday.
Five other juveniles and an adult were also inside at the time.
Police did not give an exact age for the victim but did say he is in critical condition.
About 2.5 hours earlier, a 14-year-old boy was grazed in the cheek by a bullet in the city's Summerdale section.
Investigators say this was a drive-by shooting targeting a small group that was gathered on the 800 block of Scattergood Street.
Police have not made any arrests in either case.
