"We met at an ESL class she was really kind,"Liaosaid.

"I feel like she can come out and talk with me. I can't believe she's really gone."

Safety concerns

Shen was reported missing on Tuesday afternoon,a few hours before she was found.The Integrated Homicide Investigation Team (IHIT) doesn't have any suspects in her death and said it's unclear if it was a random or targeted killing.

Valentine Wu, who helped organize the vigil, said the teen's death has taken on toll on the community.

"We use the park a lot so it's a shock to us," he said."I think what happened sent a message to other parents that it's time to talk about [safety]."

Another one ofShen'sclassmates said the neighbourhood doesn't seem the same.

"I was raised always coming here during summers," said Angelina Ravelli.

"For this to happen here, we don't know if it'll go back to the way it was before."
