In Los Angeles, Nelson is charged with two counts of murder for allegedly shooting off-duty Los Angeles County sheriff's Deputy Joseph Gilbert Solano, 50, in Alhambra and 31-year-old Dmitry Alekseyevich Koltsov in downtown Los Angeles. The shootings occurred hours apart from each other on June 10, 2019. Nelson -- a former St. George, Utah, resident -- is also charged with attempted murder and robbery for separate incidents in L.A. County. In Stephan's letter, she wrote that her office agreed early last year to let the L.A. County district attorney prosecute Nelson for the San Diego County robberies with the understanding that he would face a maximum possible sentence of life imprisonment without the possibility of parole if convicted.
