Donald Scurry Jr., 25, was arrested in the area of Commerce Street in Bridgeton on Wednesday, authorities said.
He is accused of killing 24-year-old Celeste Cannon. There was no immediate word on a motive.
Cannon is the sister of Vineland High School quarterback Isaih Pacheco, who was profiled on TV earlier this week.
Teen triumphs over tragedy to inspire others
It was noted that not only had Isaih lost his sister to violence, their 30-year-old-brother, Tavarios Cannon, was stabbed to death last year.
Still, he retained a positive attitude and unshakeable work ethic.
"I'm just going to keep my head up and thank God every day for waking me up," said Pacheco.
It could not have been a more lopsided game, led by quarterback Isaih Pacheco.
The Vineland High School Fighting Clan football team demolished their opponents in a stunning 42-6 win in Egg Harbor Township last Saturday night.
Isaih rushed for a season high 217 yards, including an 80 yard touchdown.
"I just wanted to keep working hard and every play, every chance I got the ball, I just wanted to make things happen," said Pacheco.
These achievements are all the more remarkable when you consider that only two days earlier Isaih's sister, 24-year-old Celeste Cannon, was found shot to death. The gunman has not yet been identified.
Unfortunately, these are not the only tragedies Isaih has seen in his life. He also recently lost his grandmother and his uncle.
Some other kids would have turned around and given up, but not Isaih.
His coaches said Isaih is an inspiration.
"He's a special kid," said Vineland High School Coach Dan Russo. "He's been through a lot the last year and a half and you know, we're just here to support him."
For Isaih's parents, his courage and perseverance is helping them deal with their grief.
Isaih's mother, Felicia Cannon, said he continues to be strong for her.
"I just want him to see his goal in life," she said.
Isaih's father Julio Pacheco said he wants to make sure the family is good and that he succeeds.
"He wants to be the face of his hometown and he's an outstanding kid," he said.
