He was stabbed over the weekend in Newark and died on Wednesday.
It appears to be a random attack.
"No one should have to bury their child, especially at 14," said Lowman Colclough, the victim's father.
Siah Thomas had dreams of playing basketball and loved all sports including baseball and skateboarding. His dreams ended after being stabbed for no apparent reason.
"He loved to joke around, he loved sneakers, just an ordinary kid, but now he's not going to see his adult life," Colclough said.
His father is in shock and disbelief because his son was too young to die.
"It's part of life, but I'm just hurt right now," Colclough said.
Siah was on his way to play basketball, but stopped at a skate park to skateboard with his friends. They noticed a man acting erratically and he attacked the 14-year-old boy.
"Good kid, never been in no trouble, nothing like that. He just graduated the 8th grade and was just going to finish his first year of high school," Colclough said.
The stabbing took place on Sunday afternoon in broad daylight. Police told Siah's parents the suspect chased the 14-year-old down and plunged a knife into his neck.
He died on Wednesday. Police are still searching for the attacker.
"I just pray that he can find his heart to turn himself in, I know he didn't mean it, but like I said, you do wrong, you got to pay the time," Colclough said.
