Two stabbings and four shootings in the city killed three people in a two-hour span yesterday and also left four people in critical condition over the weekend - including a 15-year-old boy who was stabbed in the back inside of a Yorktown high-rise.
The teen is believed to have been attacked during an altercation in the stairwell of the high-rise on North 10th Street near West Thompson around 8 p.m. Saturday, police spokeswoman Officer Tanya Little said.
Responding officers found the teen lying on the lobby floor of the building, suffering from two stab wounds to his back and a puncture wound to his lung, according to Central Detectives.
He was transported to Hahnemann University Hospital in critical condition and was upgraded to guarded condition yesterday, Little said.
Though officers were prevented from interviewing the boy because of his medical condition, it's believed he was with friends in the high-rise but did not live there himself, police said.
Other weekend violence, all of which remains unsolved, included:
_ 9:30 p.m. Saturday - A 20-year-old man was shot twice in his right side, once to his left forearm and once in his right cheek on North 18th Street near Albanus in the city's Nicetown-Tioga section, Little said.
He was transported to Albert Einstein Medical Center, where he remains heavily sedated and in critical condition, according to Little.
_ 12:09 a.m. yesterday - Juan Carroll, 22, was shot and killed on West Susquehanna Street near North Front in Kensington, police said.
Carroll, of Rorer Street near East Wyoming Avenue in Feltonville, was shot once in his chest and taken to Temple University Hospital, where he was pronounced dead at 3:30 a.m., Little said.
_ 2:01 a.m. yesterday - A 31-year-old woman was found stabbed to death on East Norris Street near North Front in Kensington.
The woman, whose identity is being withheld by police pending family notification, was found on the sidewalk with a single stab wound to her neck and one to her hand, Little said.
Police are having a difficult time determining where the woman is from and who her family might be since she appears to have been a wanderer, according to Homicide Sgt. Tim Cooney.
_ 2:13 a.m. yesterday - Shaka McKenzie, 18, was shot once in the neck and killed on Germantown Avenue near West Russell Street in the city's Tioga section.
McKenzie, of West Tioga Road near Old York in North Philadelphia, was carried about a half-block from the scene to Temple's emergency room, which was across the street, Cooney said.
It was there that he was pronounced dead at 4:07 a.m., according to police.
_ 2:20 a.m. yesterday - A drive-by shooting outside of the Corner Pocket Bar in West Kensington left two women in critical condition and two men in stable condition, police said.
The shooting stemmed from an argument between a man and a woman and a group of people outside the bar, at West York Street near North Leithgow in West Kensington, Little said.
The man, described as a 5'8", 170-pound, light-complexioned Hispanic male, and the woman, described as a 5'5", 130-pound, dark-xomplexioned Hispanic female, left the scene but returned later in a red pickup truck, possibly a Ford F-150, according to police.
It's unclear whether the man or the woman in the truck had the gun, but one of them opened fire on the large crowd, striking four individuals, Little said.
A 29-year-old woman was struck once in the chest and remains in critical condition at Temple University Hospital.
A 27-year-old woman, who was initially admitted to Temple in critical, suffered gunshots to her left thigh and buttocks. She was upgraded yesterday to stable condition, according to East Detectives.
A 26-year-old man, shot in his right arm and left leg, and a 29-year-old man, shot in his right foot, were both admitted to Temple in stable condition, Little said. *
