The state of Maryland has filed a lawsuit over a deadly 2008 medical helicopter crash in Prince George's County.

Maryland officials claim in the suit against the U.S. government that Federal Aviation Administration air traffic controllers responded inadequately during the incident, and failed to provide proper support to the helicopter's crew.

According to the suit, the FAA controllers gave outdated weather information, were distracted and didn't coordinate the helicopter's path to ensure its safety.

The chopper crashed in Walker Mill Regional Park in District Heights on Sept. 28, 2008, killing pilot Steven Bunker, flight paramedic Mickey Lippy, volunteer paramedic Tanya Mallard and patient Ashley Younger. Another patient, Jordan Wells, survived.

The claims in the suit echo those in three other crash-related lawsuits — filed by Wells and the families of Lippy and Mallard — that are also pending in federal court in Maryland.
