Earlier this week Kimani Gray's high school, The Urban Assembly School of Design and Construction, sent a letter to parents and staff in honor of the teen who was fatally shot by undercover cops last week after he allegedly pulled a gun on them.

The New York Post published an excerpt of the letter sent to parents and staff:

"We believed in his potential from the day he entered our school," wrote principal Matt Willoughby. "He traveled for over an hour each day from East Flatbush to Midtown West to our little architectural themed high school. The year and a half we had with Kimani allowed us to get to know his best self.

"Kimani made great strides this year academically. He was taking an extra English class after school; he was writing a dramatic dialogue in another English class; his group in Design class was working on a project to design a school. Now they are working to complete their project without him."

"He always smiled, he came to school every day, and the kids here miss him,"a teacher told the New York Post. "That says a lot."
