Police are investigating overnight shootings in Philadelphia that left three people dead and one critically wounded.
The first slaying happened when a man was shot on the 7200 block of Ogontz Avenue in the city's West Oak Lane section shortly before 10 p.m., Philadelphia police said.
A 33-year-old suffered multiple gunshot wounds and was taken to Albert Einstein Medical Center, where he was pronounced dead at 10:26 p.m., police said. His name was not released because his family is still being notified.
Then, another man was fatally shot on the 5800 block of North 5th Street in Olney just after 11:30 p.m.
Police said 20-year-old Samuel Cave was shot in his chest and pronounced dead at Einstein at 11:52 p.m.
A 17-year-old boy was also shot in his arm and abdomen, and is in critical condition at Einstein.
That incident happened near Lowell Elementary School, and police hope video surveillance is available.
"The elementary school does have some exterior cameras that are, hopefully, used to record in the evening and in the summer months," Chief Inspector Scott Small told reporters.
A few hours later, a man was shot and killed on the 2500 block of North Marston Street at about 2 a.m. At least five shots were fired in that incident, according to Small.
Police said the 32-year-old man suffered gunshot wounds to his neck, chest, arm and abdomen. His name was not released.
Detectives are still investigating the circumstances of the killings.
No arrests were made in any of the slayings, and no descriptions of potential suspects were available.
