A 46-year-old ex-convict accused of fatally shooting his ex-girlfriend and wounding her mother more than three years ago wants to challenge the constitutionality of Nevada's death penalty.
Robert Brown Jr.'s defense attorney, Andrea Luem, told a Clark County District Court judge on Tuesday that she's also preparing jury questionnaires ahead of Brown's capital murder trial, scheduled to begin Aug. 29.
Brown is accused of killing 29-year-old Nichole Nick and wounding Nick's 58-year-old mother in December 2012 in a Las Vegas apartment.
Police also reported finding a bullet hole in Nick's 3-year-old niece's bed, but the girl wasn't wounded.
Brown has been jailed since his arrest in April 2014 in Los Angeles.
He was convicted in 1998 in California of trying to kill his then-wife, and spent seven years in prison.
