Tag “drifted” means a motorist leaves a general purpose travel lane and strikes a bicyclist from behind, typically either in a bike lane or shoulder
Also see tag, strike-from-behind which is wher a motorist strikes a bicyclist from behind in the same general-purpose travel lane (not a bike lane, or shoulder), excludes unlit/unreflectored bicyclists; tag strike-from-behind-unlit
This is an outline of each 2016 fatality that was unknown to me — or that could not be found by reverse-googling — until the database was released in mid-2017. See the full 2016 grid here.
There are 10 such incidents, not counting two additional exceedingly poorly-documented incidents that were also nowhere to be found in media report. That means that of total of 30 fatal incidents (31 fatalities, as one was double) in 2016, 18 were reported in the media while 12 were not — or at least not that I can find.
This article is a catch-all for any reported Arizona bicyclist traffic fatality that are otherwise unknown — no media, or any other, coverage could be found; they are only listed as statistics in the crash database.
I don’t know what “criminal charges are possible” means; but once more-serious criminal charges have been ruled out — cases where a same-direction motorist drifts causing a rear-end collsion with a bicyclist in a bike lane (or a shoulder), on its face, should trigger a misdemeanor “causing death by moving violation” charge, see arizona-already-has-a-vulnerable-user-law
June 7, 2016 ~ 5:30A 73 y.o. bicyclist Calvin Ray Sapp was killed after being struck by a hit-and-run driver in a bike lane — southbound on Higley Road midway between Ocotillo and Chandler Heights roads. A vehicle matching the description was found a short time later and a suspect was arrested. A later news story that evening said that the suspect “…told police he fell asleep and didn’t know what he hit. Officers said the bike and victim were dragged about 80 yards”. And carried some more-graphic pictures of the smashed in windshield. They also identified the Phoenix Police officer credited with finding the suspect vehicle.
4/14/2016 Bicyclist Donald Neu was killed riding westbound Riggs Road near Arizona Ave when he was struck by a driver who “drifted” into the rather wide, designated BL.
Note that, according to that description of events, the driver has “failed to keep proper lane” (§28-729) and should be charged with 28-672, a criminal misdemeanor — assuming other more-serious charges are ruled out. Are police (in this case, MSCO) aware of this? In this triple serious injury, they were.
28-735 is all well-and-good, and as far as I know can be “stacked” on 28-672, but it (28-735) is nothing more than a fine.
