New York (PIX11) — More than 50 Asian American and Pacific Islander (AAPI) groups from across the country have released an open letter calling for justice for Akai Gurley.

The unarmed, 28-year-old was killed by NYPD Officer Peter Liang on Nov. 20, 2014.

Officer Liang was conducting a vertical patrol in the Louis H. Pink Houses in East New York when he fired a shot that killed Gurley, who was visiting the home of his girlfriend.

The Asian American and Pacific Islander organizations who have signed the letter represent diverse constituencies across all regions of the U.S. The letter has also been signed by almost 200 leaders in the Asian American and Pacific Islander community.

The release of the letter follows calls from some Asian Americans for the charges against Officer Liang to be dropped.
