Philadelphia police still have no suspects in last Tuesday's fatal shooting at the 37th Street SEPTA trolley station.
According to Philadelphia Police Sgt. Tim Cooney, the department is still conducting interviews in regards to the case and has made no definitive progress.
"There's nothing productive coming out of our efforts at this time," Cooney said.
On May 16, two men were shot in an early morning incident on the eastbound Green Line trolley platform at 37th Street.
Twenty-three year old Philadelphia resident Derrick Nalley was shot in the upper torso by an unknown assailant at about 6:40 a.m. while on his way to work. Nalley was pronounced dead at the Hospital of the University of Pennsylvania at 8:29 a.m., police say.
The other victim was 34-year-old Philadelphia resident Joseph Quinn, who suffered a minor bullet graze to the back and was released from HUP that day.
Some students are concerned that the shooting took place so near to student residences such as the Quadrangle.
College senior Tony Le, who lives in Fisher-Hassenfeld College House, uses the 37th Street SEPTA station often.
He said that he would continue to use the station, but the shooting might make him more hesitant to ride the trolley alone.
"It's kind of disturbing," Le said. "It's surprising because [Penn officials] increased security so much, and it makes you wonder if all that security is working."
Division of Public Safety officials do not have any changes in security planned in response to the incident. However, DPS officials said that students concerned that security is relaxed over the summer have nothing to worry about.
"The Division of Public Safety and University of Pennsylvania Police Department work in full force all year round," DPS officials said. "We are currently reaching out to faculty, staff, remaining students, and guests who are visiting campus this summer with information on available safety services and safety tips."
One factor that has hindered the investigation is that the 37th Street trolley station does not have surveillance cameras.
According to spokesman Richard Maloney, SEPTA is currently in the process of installing sercurity cameras in its stations.
The 37th Street station is "one of dozens expected to get cameras over the next several years," Maloney said.
However, Maloney stressed that the plan was already in the works and is independent of last week's incident.
