Who murdered lucy?

20xx
There's this girl, Lucy, who was the same age as me, and they found her body in a cardboard box at an abandoned playground. I didn't know her, but I might have caught a glimpse of her getting cozy with someone at a deserted lot hidden by trees and tall grass once.

From what I've heard on the news, she had it all—wealthy parents, living the high life. But then they say she started stealing from them for drugs and got involved in other stuff, too. But her being murdered? That's messed up. I'm stuck wondering—should I come forward about what I saw? Will it put me in danger? In this rundown neighbourhood, we keep to ourselves.
