NBC New York – The New Jersey cheerleader who was shot dead  in an apparent robbery on Tuesday knew her killer, sources say.

Amber Wilson, 18, who graduated from high school less than a month ago, was walking to her Hussa Street home in Linden with a friend just before midnight Tuesday when an unknown number of men approached them, said officials.

Wilson was robbed; an argument ensued and Wilson was shot, prosecutors said. She died at the scene.

“We hope they apprehend the person that did this, this senseless loss of life,” Wilson’s father Norman Duncan told NBC 4 New York as he held his sobbing wife, who was Wilson’s stepmother, at a vigil Tuesday evening near where the teen was gunned down.

Hundreds of Wilson’s classmates, cheerleading teammates and friends came to honor how she lived her short life, paying tribute to her spirit and her smile.

“Amber, you were a light of this city, the cheerleading team, you were such a shining star,” said a friend as she cried.

Friends said Wilson graduated from Linden High School on June 22 and that she was an active member of her school community, serving as co-captain of the cheerleading team, participating on the dance squad and helping raise money for prom.

Fliers advertising a $5,000 reward for information leading to an arrest were distributed.
