At least four people were killed and nine others, including two police officers, were injured in a shooting in Farmington, the US State of New Mexico, police said.
An 18-year-old man suspected of carrying out the attack was "confronted and killed on scene," police said.
Two officers, one from the Farmington Police Department and one from New Mexico State Police, were shot and listed in stable condition at a hospital, Farmington police said in a statement.
Authorities said that the gunman stalked through a New Mexico neighborhood on Monday firing randomly at bystanders, houses and cars.
No motive was readily apparent, police said.
Monday's mass shooting was the latest in a string of deadly attacks in the US in recent weeks. In Texas, eight people were killed in a shooting at a mall in Allen just over a week ago. An officer shot and killed the shooter there.
In Cleveland, Texas, a man was arrested and charged in the killing of five people earlier this month, over complaints that he was firing a gun late at night. The suspect was taken into custody after an extensive manhunt.
