On January 10, 2015, Jason Stratos, 40, was one of three men found shot to death inside a first-floor apartment on the 4600 block of Vista Street in the Holmesburg section of Philadelphia. Officers arrived at about 11:23 p.m. and discovered Stratos and two other victims, Ramon Ortiz, 40, and Sarith Mang, 30, each with gunshot wounds to the head. All three were pronounced dead at the scene.

The killings were described as execution-style and investigators have suggested they were likely connected to drug activity; all three victims were known to police. A sign in the apartment reading Trespassers will be shot. Survivors will be shot again was noted at the scene. Detectives said the murders appeared planned and that progress has been hampered by a lack of cooperative witnesses and limited evidence. No arrests had been announced immediately after the killings and the case remained unsolved.

Does anyone who knew Jason or the other victims have information that could help investigators?
