"It appears that these victims were hanging out on the front steps of a corner property at 17th and Bristol because we found some alcoholic beverages and some other drinks, and that's where we found most of the blood evidence," said Chief Inspector Scott Small of the Philadelphia Police Department.
No arrests have been made. Anyone with any information is asked to call police at 215-686-TIPS.
The triple shooting comes just 24 hours after an explosion of gunfire on the basketball court in the city's Spring Garden section. That shooting left two people dead and three others injured.
More than 1,400 people have been shot in the city this year.
