On the evening of February 16, 2017, in the East Mount Airy neighborhood of Philadelphia, 24-year-old Raheem Martin and his 23-year-old brother, Symir Yelverton, were found in the rear driveway of a home on the 300 block of Upsal Street after gunfire was reported around 10:30 p.m. Both brothers suffered multiple gunshot wounds to the chest and torso and died a short time after being taken to Einstein Hospital.

Police say the shooting followed an escalating dispute in the neighborhood. Investigators report Symir was involved in a physical altercation with a group of men, and Raheem was shot after coming out to help his brother; witnesses described four men fleeing on foot. The Philadelphia Police Department’s homicide unit opened an investigation and said a month later they were making progress, though no arrests have been publicly announced.

Does anyone have information about the night of February 16, 2017, or remember seeing four men leave the area that evening?
