C.O.P. Out is the sixth in the Elena Jarvis series by Nancy (Fairbanks) Herndon. I remember reading this series, set in a thinly disguised El Paso, IMS, back in DTB days, and enjoying most of them. Out has dropped to $1.99 at Kindle and Kobo US (coupon/VIPable).

Spoiler:

Elena Jarvis, a police officer from Los Santos, Texas, has succeeded against all odds. Now she confronts possibly the biggest, most politically charged mystery ever. When a volunteer with the Citizens on Patrol (C.O.P.) program, last seen patrolling with a rookie officer, is found murdered, Elena must work fast to find the true murderer or take the heat with the rest of her department. Elena is not comforted by the fact that the victim was the wife of one of the mayoral candidates—who is of course using his wife’s death to turn the polls around. Only the sharp‑witted Elena Jarvis can succeed at such a complex case—and if she does not, she is the next suspect.
