UPDATE!  They have a suspect in custody.  Great job US Marshals, Philadelphia PD, Temple University PD and Buckingham Township (and any other agency involved).
 

The men and women of the NPPD send our deepest sympathies to the Temple University Police Department.  One of their officers was shot and killed in the line of duty around 7 p.m. in Philadelphia tonight.  This has to end!
