FIVE people have been killed in Yuma, Arizona, in a multiple shooting incident which triggered a temporary school lockdown.

US authorities have identified the man suspected of fatally shooting five people and wounding one other in southwest Arizona, and they say he has killed himself.

Yuma police say the shooter was 73-year-old Carey Hal Dyess of Yuma. They say Yuma County sheriff’s deputies found Dyess dead of an apparent self-inflicted gunshot wound.

The shootings happened on yesterday morning. One person was killed in the downtown Yuma area, while the other four were killed in Yuma County. The wounded person was flown to a Phoenix-area hospital.

Police say an investigation determined the shootings were linked.

Authorities have not released the victims’ names, but say the person killed within city limits was an adult male. They say Dyess entered a business and shot him
