A 36-year-old Philadelphia man wanted in a 2018 killing in that city that was shared on video was arrested Monday morning in Allentown, the Northampton County Sheriff’s Department announced.

Philadelphia police in recent days learned Samuel Sithisong had been in Lehigh County Jail but was freed Feb. 21 on $25,000 bail on a charge of recklessly endangering another person and two unspecified offenses, records show.

On Monday, the U.S. Marshal Service’s Violent Fugitive Task Force, which includes marshals, the sheriff’s department’s Criminal Warrant Unit as well as Pennsylvania State Police and state probation and parole agents, tracked Sithisong to the 2000 block of Cedar Street and arrested him without incident about 6 a.m., the news release said.

Sithisong was briefly held without bail in Lehigh County until he was returned to Philadelphia to face charges of murder, aggravated assault, criminal conspiracy and recklessly endangering another person from an Oct. 14, 2018, incident, records show.

Philadelphia police allege Sithisong was among a group of 10 men and two women who attacked Brett Berdini, 28, and his girlfriend Shaina Hicks about 1:55 a.m. in the 1000 block of Race Street, court papers say.

Berdini underwent several surgeries at Hahnemann University Hospital to repair damage to his heart and lung, but he died three days later from his injuries, police said. Hicks suffered a broken nose, among several injuries, police said.

Not only was there surveillance video of the attacks but those involved took and shared cellphone videos of the crime via text message, police said.

Victor Yan is seen stabbing Berdini in the chest in video that was found on the phone of an inmate at the state prison at Smithfield, police said. Records don’t show Yan in custody.

Video also shows an Asian man kicking Berdini several times while he is on the ground and punching him as he tries to walk away, police said. When Berdini falls to the ground again, the bald man wearing a black jacket, gray hooded sweatshirt, black Adidas plants and sneakers kicks and stomps him, police said.

Witnesses in recent days were able to identify the people at the attack scene via various videos and the man in the black jacket was initially identified as Sam, police said. Another witness said Sithisong contacted them and said, “I have something to show you,” police said. It was a video of the assault and the people involved in the attack were known to this witness, police said. The witness identified to police all the people in the video, including Sithisong, police said.

Sithisong was arraigned early Tuesday in Philadelphia Municipal Court and held without bail, records show. Five codefendants are listed in court papers.

Court papers don’t list an attorney of Sithisong.
