NEW YORK (CBSNewYork) — There was sadness and sorrow Tuesday at the wake for the Manhattan teenager who was stabbed to death just hours after his high school graduation.

Friends and family gathered in Midtown to pay their respects to 19-year-old star high school football player Isayah Muller. The wake for Muller will continue through Wednesday with his funeral set for Thursday at Sacred Heart Catholic Church in Manhattan.

“It’s peaceful, you know, a lot of people was crying remembering Isayah. He was a good kid, you know?” the victim’s cousin, Emanuel Enang, told CBS 2’s Derricke Dennis.

At the Barrett Funeral Home on West 51st Street, Isayah’s grandmother and parents were left to mourn their loss. Many at the wake wore white T-shirts with Muller’s picture, still grieving over his stabbing death just hours after graduation from Truman High School in the Bronx.

Amando Santos, a friend of Muller’s since middle school, said he still can’t believe Isayah is gone.

“Everybody is trying to cope. His grandmother was a little…but everybody is fine,” Santos said.

It was one week ago Tuesday that Isayah was killed while helping his father in a fight at a Bronx parking lot. Prosecutors said surveillance video at the scene showed his dad was the aggressor.

Andre Muller, 40, was charged with assault and accused of using a shovel to attack two parking lot attendants over a missing bottle of cologne from the family car. Isayah was stabbed to death in what prosecutors said was an act of self defense by the attendants.

A grand jury has been looking at evidence to decide whether the parking attendants should face charges.

Muller is being remembered as a football hero and friend.

“There was no reason to kill him. Justice needs to be served, and I feel like they need to be charged,” Santos said.
