WASHINGTON (CBSDC/AP) — The nine people killed in a Metrorail crash in June 2009 in northeast Washington will be honored with a plaque near the crash site next month.

District of Columbia Mayor Vincent Gray will join relatives of crash victims, first responders and the chairman of the National Transportation Safety Board to unveil the plaque on June 22.

The crash was the deadliest in the transit system’s history. A malfunctioning electronic circuit caused two trains to collide near the Fort Totten station, killing a train operator and eight passengers. Eighty others were injured.

The announcement that a plaque will honor the deceased comes just two days after the community publicly opposed the city putting in a permanent memorial. The local residents cited that they already use the space for block parties, and any added benches may encourage kids to have sex in the secluded area.
