The first death was reported shortly before 6 p.m. in Northwest Philadelphia and ended at 1:15 a.m. in West Philadelphia. The victims were four men and two women, four died by gunfire, two from stabbings.

Mayor Nutter, at an unrelated City Hall press conference this morning, acknowledged that "last night was a bad night."

At the same time, he told a reporter, "If your question is, is this city safe, it is certainly safer than it has been, but we have work to do." Nutter noted that even with last night's killings, the overall homicide numbers are 20 percent lower than they were at this time last year.

The mayor also mentioned that two of the six deaths were the result of domestic disputes. "We can't put police officers obviously in people's homes."

The killing began near sundown.

As dusk began to fall around 5:30 yesterday, two armed men approached a car in Northwest Philadelphia and assassinated a 21-year-old man.

There were three passengers in the car who escaped the gunfire on foot. Police do not have a motive.
