A lawyer for a mother who viewed Nevada state police dash cam video of the last moments of her son's life says he's confident it will help in a federal lawsuit stemming from the fatal shooting by U.S. Bureau of Land Management officers.

Testimony revealed during a public airing of evidence Monday in Las Vegas that 20-year-old D'Andre Berghardt Jr. shrugged off stun-gun darts before he was shot and killed trying tried to get into the trooper's cruiser on a state highway near Red Rock Canyon National Conservation Area.

No findings or conclusions were made after the hearing.

Attorney Jacob Hafter said Tuesday that the information will help the federal wrongful-death lawsuit Burghardt's mother, Tracy Meadows, has pending against the federal agency and officers Meagen Martin and Brian Loftin.
