Friends and family have identified the 17-year-old shot and killed by police this weekend as Cyrus Green. Green was fatally wounded by an Edmonton officer early Saturday morning.

The Alberta Serious Incident Response Team (ASIRT) is now investigating the case.

The incident started after police responded to a weapons and robbery complaint at the Coliseum ETS Station around 12:30 a.m.

Police officials report a suspect was soon located near 118th Avenue between the north and southbound portions of Wayne Gretzky Drive. And according to an EPS spokesperson, the situation "escalated," leading an officer to use lethal force.

ASIRT director Clif Purvis has said initial reports indicate the teenager was charging at police before he was shot three times.

ASIRT has recovered the knife and bat that were involved in the incident. Officials report they will rely on evidence from the EPS Forensics team and will gather statements from all witnessing officers and anyone else who may have seen something.

Investigators said the suspect fled from police and during the pursuit, approached a uniformed officer while in possession of a knife and bat.

"The individual, from what I understand, was running at the police officer and was shot at a distance of six to eight feet from him," said Purvis.

But Green's friends told CTV News they don't police reports that the 17-year-old charged officers with a bat. The teen's friends are now questioning police actions.

"They could have tackled him, they could have Tasered him, they could have called for more backup... that is overkill, shooting someone three times," said Shane Morley.

The victim was transported to a local hospital for emergency surgery, but eventually succumbed to his injuries.

A pole located close to where the shooting occurred is now surrounded by mementos including a teddy bear sporting an Edmonton Oilers and several cards. One card, by 'Dad', states: Till' we see one another again Bone."

Another note, signed 'Mom' reads: "I will always miss you my son, but I know that one day we will see each other again soon. Just not today."

Another friend, who didn't want to be identified, describes the teen as quiet and funny. Although, those who knew the teen allude to a troubled past.

"He was trying to change, he was trying to go back to school -- get his life back together," said Morley.

In this particular case, a man with five years experience on the force is under investigation. It is not known at this time where the other officers were when shots were fired, and if anyone on scene was equipped with a Taser.

Purvis said there were calls of a mugging in the area around the same time as the shooting took place, and two people are in custody in connection to the crime.

A number of officers are now on mandatory administrative leave for about five days and are receiving stress debriefing.

ASIRT continues to investigate.
