SEATTLE — The Redmond police officer who shot and killed Andrea Churna, an unarmed 39-year-old mother as she tried to surrender to officers in September 2020, had been dismissed as a probationary Whatcom County sheriff’s deputy 14 months earlier for poor performance, according to records.
Daniel Mendoza, 26, struggled with virtually every aspect of police work during his seven months as a probationary sheriff’s deputy, unable to recite statutes, routinely getting lost while responding to calls, writing muddled reports and failing tests on topics ranging from when using force was appropriate to the county’s pursuit policies.
The preceding 720 hours he spent learning to become a peace officer at the Washington State Criminal Justice Training academy wasn’t much better — while he looked sharp and was enthusiastic, he was last in his class academically, and repeatedly failed a key test mock scenario, preventing his graduation. The academy only certified him as a peace officer after Whatcom County intervened to help him pass on his third and last try, according to personnel records obtained through public disclosure by The Seattle Times.
“Deputy Mendoza also has had knowledge deficiencies in the area [of] RCW [Revised Code of Washington], policy and case law,” wrote Whatcom County Deputy Chief Doug Chadwick in a memo to field training Lt. Rodger Funk in May 2019, after Mendoza’s second failed attempt at passing the first phase of field training under an experienced training officer. The revised code is a compilation of all permanent state laws.
