A disturbingly high number of fatalities Friday and Saturday, with nine people killed in roughly 24 hours, Arizona Department of Public Safety officials said.
DPS between Friday and Saturday mornings responded to seven fatal crashes, including one near Flagstaff that caused three deaths.
Another fatal crash took place in Apache Junction just before noon Friday, when an unidentified man ran across U.S. 60 near Ironwood Drive and was struck by an oncoming vehicle.
The man, in his early 20s, had just been dropped off at the side of the freeway after hitching a ride moments earlier near Ellsworth Road, a few miles west. There he was believed to have caused a two-vehicle crash in which he was the driver of one car.
A collision on Interstate 10 near the California border Saturday morning killed one motorist, left one in critical condition and caused less severe injuries to four others.
Also Saturday, one person was killed on State Route 95 near Lake Havasu. Another person was killed on State Route 79 near Florence.
On Interstate 40 just outside Flagstaff early Friday three people pushing a vehicle out of a snowbank ran to avoid an oncoming tractortrailer but were all struck and killed.
The other two collisions were single-vehicle crashes involving motorists who lost control for as-yet-unknown reasons, Martin said.
One was at 6 a.m. Friday on State Route 85 north of Ajo, when a single vehicle skidded, rolled over and killed the driver, who was alone.
The other was on I-40 near Jackrabbit when the driver lost control, was ejected from the vehicle and then run over by a semi.
