The Reno Police Department has defended its investigation and arrest of CheMarion Cooks after the Washoe County District Attorney declined to file charges in the 2023 Zephyr Pointe apartment shooting. The DA's office cited insufficient admissible evidence to prove the case beyond a reasonable doubt. Reno police described the case as "tragic" and "complex," emphasizing that detectives devoted significant time and resources to investigating all available leads. The department also stated that successful prosecutions depend on collaboration between investigators and prosecutors. The decision has been criticized by District Attorney Christopher Hicks' sole challenger, Sparks City Attorney Wes Duncan, who argued that the decision leaves victims without justice and allows crime to persist.
