(Portland, OR) -- The estate of Ryan Martin is seeking 40-million dollars in damages from Uber, Multnomah County, and convicted killer Geoffrey Hammond. Martin was shot and killed by Hammond in a 2023 road rage incident, for which Hammond is serving a life sentence. The lawsuit claims Multnomah County should never have approved Hammond's concealed carry license, pointing to prior arrests and a protection order filed in Illinois. It also alleges Uber failed to conduct an adequate background check and allowed Hammond to drive while armed in violation of company policy.
