Three men were killed in the city this weekend and one was arrested for assault after he allegedly drove into a police officer who was approaching his car on foot.

In the first homicide, a 39-year-old man was fatally shot in the head last night at 7:46 in Southwest Philadelphia.

Police did not provide many details of the shooting in a home on Trinity Street near 68th and did not identify the victim pending family notification.

Alexis Wood-Bowen, who lives across the street from the home, said this is rare for the neighborhood.

"I can't believe this," she said of the man who had lived in the house for 16 years.

"It's quiet out here except for the kids playing."

On Saturday, a 39-year-old man, whose identity is being withheld pending family notification, was shot three times on Woodlawn Avenue near Chew in Germantown about 12:30 p.m. police said.

The victim, who was hit in the head, chest and right hand, was taken by police to Albert Einstein Medical Center, where he was pronounced dead at 1:02 p.m.

At 1:27 a.m. on Saturday, officers en route to reports of shots fired in North Philadelphia spotted an orange Grand Marquis speeding south on Broad Street, Homicide Sgt. Bob Wilkins said.

The officers followed the vehicle to Temple University Hospital, where the driver told them his passenger had been shot, Wilkins said.

Yusuf Sweet, 22, of North Philadelphia, was shot twice in the back while in the same car on 65th Avenue near 21st Street, police said.

It was unclear if the car was parked or moving at the time of the shooting.

Sweet was pronounced dead at Temple at 1:53 a.m.

In a separate incident Saturday, shortly after noon, two officers on patrol on Drexel Road near Haverford Avenue in West Philadelphia saw a silver Mercury Sable make a reckless turn in front of oncoming traffic, police spokesman Lt. Frank Vanore said.

When the officers ran the vehicles tags, the tags came up stolen and they attempted to initiate a stop, police said.

The driver, later identified as Brian Baylor, 23, pulled into a driveway on Woodbine Avenue near Haverford and subsequently backed into the rear of a home on 75th Street near Woodbine, Vanore said.

As the officers approached the front of the car on foot, Baylor allegedly knocked one of them to the ground with his vehicle and fled.

The stricken officer's partner fired one shot, hitting the car but missing Baylor, police said.

The car was found soon after on Farrington Road near Brockton and Baylor, who lives in that area, was stopped on foot a few blocks away on Malvern Avenue near 76th Street.

He was charged with assault on police, receiving stolen property and related charges.
