CBS News reported that seven people were killed in a two-location mass shooting in the northern California coastal town of Half Moon Bay on Monday, with a suspect in custody.
Half Moon Bay is located about 50 km south of San Francisco.
The San Francisco Chronicle, citing the Department of Homeland Security, said investigators arrested the 67-year-old man about two hours after the incident.
The newspaper reported that the weapon was found in his car.
It says that security personnel who acted on the distress call found four dead and a fifth injured at the first location in Half Moon Bay, and then found three more dead at another location nearby.
In another incident, police said Monday that two students were killed and an adult seriously injured in a “targeted” shooting at a nonprofit educational center for at-risk youth in Des Moines, Iowa.
Three suspects, whose identity could not be identified, fled the scene in a car, after which they were detained at a checkpoint within 20 minutes of the incident.
Authorities have not established a motive for the shooting.
The incidents in California and Iowa occurred as tensions still lingered in the Los Angeles County city of Monterey Park following Saturday’s mass shootings that killed 11 people.
