Geoffrey Boshell, 22, was working on a school project when he heard the chilling sound of rapid gunfire from his window.
He said: "I heard it, looked out my window and immediately see people screaming, fleeing the scene.
"I'm not sure scared is the right word. Just very disturbed that it was happening right outside where you are living."
Cops are still said to be investigating if the gunmen walked up to the victims or was in a car when they fired the shots.

Over 100 shell casings were found in the area, say police.
No arrests have been made as of yet.
Officer Fitzgerald said: "Rest assured, we are going to do everything we possibly can to uncover, identify and hunt down whoever was responsible for preying on our people."

Birmingham Mayor Randall Woodfin declared the weapons are "the number one public safety issue" in the city.
He has called on them to be outlawed after the attack.
Woodfin made a passionate plea for safety at a press conference on Sunday as he said: "We find ourselves in 2024, where gun violence is at an epidemic level, an epidemic crisis in our country.
"And the city of Birmingham, unfortunately finds itself at the tip of that spear.
"Elected officials locally, statewide and nationally have a duty to solve this American crisis, this American epidemic of gun violence."
There have been more than 400 mass shootings across the US this year, according to .
The nearby streets where the shooting took place have all been closed off as cops continue to search the area.
