Philadelphia police on Friday released two pictures of a man they believe fatally shot another man on a West Philadelphia street Thursday before speeding from the scene on a dirt bike.

The killing was one of three in the city Thursday, a day during which eight others were shot and wounded in street violence, according to Philadelphia police, continuing a bloody year on pace to break records.

The West Philadelphia slaying was potentially sparked by road rage, and it helped to push the city’s homicide total to record-pacing heights. Already this year, 255 people have been slain, police statistics show — a 36% increase over last year’s pace, and a higher number of victims than in all of 2014.

In the potential road-rage outburst, a man on a dirt bike fatally shot a 37-year-old man just after 6:30 p.m. near 52nd Street and Girard Avenue in West Philadelphia, police said.

The two pictures police released of the suspect show him sitting atop a green dirt bike. Police described him as a Black with a thin build wearing a blue and white Troy Lee Designs GP Yamaha Jersey long sleeve shirt with graphic patches on the sleeves, blue jeans, white sneakers, and a black full-face mask.

Anyone with information on the suspect’s identity or whereabouts is asked to contact the Philadelphia Homicide Unit at 215-686-3334 or leave an anonymous tip at 686-TIPS.

Authorities still have not released the victim’s name. Police told Fox29 that several motorcycles may have been involved in a confrontation with the driver before a man on one of the bikes turned his attention toward the motorist and fired six shots.

It marked the second time in as many weeks that a victim was gunned down on a city street by a rider on a dirt bike. On Saturday night in Port Richmond, police said, a man on a dirt bike fatally shot Angel Rodriguez, 21, after hundreds of people had gathered to watch illegal street racing.

City officials, police, and community leaders are bracing for a violent summer, even as the pandemic wanes. In City Hall, lawmakers used budget negotiations with Mayor Jim Kenney’s administration to push for more funding for violence prevention programs outside of policing.

Elsewhere Thursday night, a 29-year-old man was shot once in the left side of the chest around 8:43 p.m. on the 300 block of South 53rd Street in West Philadelphia, police said. The gunman is believed to have fled the scene in a white Nissan. Medics took the victim to Penn Presbyterian Medical Center, where he died at 9:05, police said.

About an hour after that incident, police said, a 25-year-old man was fatally shot and a 24-year-old woman was wounded in a shooting on the 4800 block of North Franklin Street in Olney. Police did not identify either victim or provide details about a motive or suspect.

The man was shot once in the chest and pronounced dead at Einstein Medical Center, police said. The woman was hospitalized in stable condition after being shot once in the left heel.
