Authorities are searching for Kaiseem Smith and Azzubair Outen-Fleming, both 16, in connection with the killing.
Schmidt, 22, was shot and killed June 6 in the 1900 block of Durfor Street. The Penn State senior was gunned down just yards from his family's home around 1:30 a.m.
Family members said Schmidt had been returning from a nearby bar where he had been watching an NBA Finals game with friends.
Surveillance video obtained by investigators appears to show the moments leading up to the shooting. In one video, a person is seen throwing a cellphone. Seconds later, another individual runs around a corner with Schmidt chasing after him. Police said the gunman then turned and shot Schmidt in the chest.
Earlier this month, police released video of the wanted suspects.

Anyone with information is asked to call 215-686-TIPS.
