"They did mention that they were partaking in the smoking of some marijuana. They pulled up to this location, stopped, and then they noticed an African-American male, about 6 feet tall, wearing a black hat, Army fatigues and a bullet-proof vest who just commenced to firing," said Detroit Deputy Police Chief Renee Hall.

Here are the victims:

Paige Stalker, 16, killed

Demetrius Herndon, 16, shot in shoulder

Girl, 16, shot and in critical condition

Boy, 15, shot and in critical condition

Girl, 17, not injured

Stalker was a junior at University Liggett School in Grosse Pointe Woods. In a statement, the school said, "As you can imagine, we are heartbroken over the death of one of our students, and our thoughts and prayers go out to her family and friends and to the entire Liggett community during this very difficult time."

"We do not believe this was a random attack," said Detroit Police Chief James Craig. "We're still working very hard to find out what took place. Candidly, there has been some challenges for us in terms of the accounts of what's taken place. So, we're asking for full cooperation."

Approximately 30 shell casings were found at the scene.
