MESA, Ariz. — A man drove himself to a hospital on Sunday afternoon after a shooting involving occupants of two vehicles near Greenfield Road and U.S. 60 in Mesa, police said, in an incident that closed a major surface street at one of the East Valley’s busiest freeway interchanges for more than three hours.
Mesa police responded to the area at about 2:30 p.m. on Sunday, October 18, for calls of a shooting, according to Detective Robert Katz of the Mesa Police Department, speaking to the Arizona Republic. FOX 10 Phoenix, reporting the same police account, said officers responded to a report of a shooting involving people in two separate vehicles near Greenfield Road and US 60 at around the same time, about 2:30 p.m.
A man who suffered an injury consistent with a gunshot wound drove himself to a nearby hospital for treatment, according to police accounts carried by both the Republic and FOX 10. The extent of his injuries was unknown, Katz told the Republic. Police have not publicly identified the man, and neither source reported his name, his age, or the hospital where he was treated. Those details remain unknown tonight, and Previously is not filling them in from any other incident.
Everyone believed involved was located, police say
Officers located all the people believed to be involved in the shooting, Katz said, and police said there was no known ongoing threat to the community. FOX 10 reported the same two points in its account: all people involved in the shooting were located by police, and Mesa police said there is no threat to the community while the investigation continues.
That distinction matters for how residents near the interchange should read the rest of the evening. A shooting investigation can remain active for hours — with detectives still interviewing people, documenting a scene and working out a sequence of events — even after police have accounted for everyone they believe took part. Sunday’s case, on the public record so far, sits in exactly that posture: the people are located, the road is open again, and the underlying questions about what happened between the occupants of two vehicles have not yet been answered publicly.
Greenfield Road closed at the freeway, then reopened by 5:45 p.m.
Greenfield Road was closed in both directions at U.S. 60 during the investigation, according to Katz. The roadway had reopened in both directions by 5:45 p.m., he said — a closure window of roughly three hours and fifteen minutes from the initial 2:30 p.m. response, spanning the late-afternoon hours when Sunday traffic builds on both the freeway and the surface streets that feed it.
Greenfield Road is a major north-south arterial in east Mesa, and its interchange with US 60 — the Superstition Freeway, the principal east-west freeway serving Mesa, Gilbert and Apache Junction — is one of the corridor’s regular pressure points. A full closure in both directions at the freeway does not only affect drivers already on Greenfield; it pushes neighborhood and cross-town traffic onto the neighboring arterials that also cross the Superstition Freeway, and it can back traffic up toward the freeway ramps themselves. Police did not announce a specific detour in the accounts published Sunday, and neither source described crashes or additional injuries connected to the closure itself.
For drivers checking conditions after an incident like this one, the Republic noted the standing state resource: motorists can check az511.gov, use the AZ511 app, or call 511 for real-time highway conditions. That guidance is worth repeating here precisely because Sunday’s closure has already lifted — the same tools that would have shown the Greenfield closure in the afternoon are the ones that confirm, in real time, that a corridor has cleared or that a new restriction has replaced it.
What police have not said — and why it stays labeled unknown
The public record on this shooting is deliberately narrow, and the honest version of this story has to name its edges. Police did not disclose how many people were involved in the shooting, according to FOX 10. Police did not release information on who fired a weapon. And the events leading up to the incident were also not released. The Republic’s account carries the same limits: beyond the time, the place, the two-vehicle framing, the injured man’s trip to a hospital and the road closure and reopening, Katz’s public statement on Sunday did not establish a motive, a sequence, or an account of any dispute between the vehicles’ occupants.
No arrests or charges were announced in either source. That is not a detail to soften or to speculate around: as of the reporting published Sunday evening, Mesa police had described an active investigation with everyone believed involved located, and had not announced that anyone had been arrested, booked or charged in connection with the shooting. Any description of the gunfire itself therefore stays in alleged terms — an alleged shooting involving two vehicles — until police or court records establish more.
It is also unknown whether the man who drove himself to the hospital was an occupant of one of the two vehicles, whether anyone else was injured, and whether the vehicles remained at the scene when officers arrived. Neither the Republic nor FOX 10 reported answers to those questions, and Katz’s statement, as published, did not provide them. Previously will update this story if Mesa police release the number of people involved, the injured man’s condition, or any account of what led to the shooting.
An active investigation at a busy East Valley interchange
What is established tonight is a compact timeline. At about 2:30 p.m., calls of a shooting brought Mesa officers to Greenfield Road and US 60. A man with an injury consistent with a gunshot wound reached a hospital by driving himself there. Officers located everyone believed to be involved and said there was no known ongoing threat to the community. Greenfield Road, closed in both directions at the freeway during the investigation, reopened by 5:45 p.m. The investigation remained active, Katz said.
For the rest of the Valley’s Sunday, the contrast was sharp: while police worked the Greenfield interchange in Mesa, football decided a very different kind of afternoon across the metro — see Previously’s account of the Cardinals’ 18-16 win over the Rams, settled by six field goals. In east Mesa, the day’s open questions belong to detectives, not to the scoreboard, and they remain open tonight by the department’s own account.
